Remote Temperature Monitor Reviews
Ideal Sciences Temp Stick Review – “Best Remote Temperature Monitor”
Temp Stick Review:
The Temp Stick by Ideal Sciences is our top pick as the best remote temperature monitor. There are a number of reasons why the Temp Stick was chosen, including its versatility, features and feedback from existing users of the product as you’ll see later in this review. It is proudly made in the USA by Ideal Sciences and runs on (2) AA batteries that are included with your purchase and have an average battery life of 1 year, but can vary depending on the settings.
One of the top reasons the Temp Stick was chosen as the best remote temperature monitor was because of its versatility. It’s an all-in-one device that doesn’t require any outside gateway device to connect to it your wifi network. There are no auxiliary sensors or monitors and no subscription service needed to get the most out of the Temp Stick. Everything is wireless! Once you’ve paid for this product, you have everything that you need, including unlimited data logging and temperature history via the free iPhone or Android cell phone app. There is also a version of the Temp Stick app that is web-based for users that prefer using a computer setup over a mobile phone or tablet.
In addition to temperature, the Temp Stick also records humidity levels, which can tell the user additional information that can be important. For example, a spike in humidity might be an indicator of a major issue. With the wifi connectivity of the Temp Stick, you can monitor the temperature and humidity from anywhere an internet connection is available, 24 hours a day, 7 days a week. It allows for multiple contacts to be notified of alerts, which along with the 24/7 monitoring, should ensure that you never miss an issue detected by the Temp Stick. Do you need more than one sensor? No problem, you can connect an unlimited number of Temp Sticks to the same account!
Alerts / Notifications
The customizable alerts on the Temp Stick setup make it very user friendly. You can program alerts within the app to notify you by text or email when the temperature or humidity hits preset limits for highs and lows. The notifications can be set to go out to up to 10 different contacts and are customizable so different contacts can receive different alerts if needed.
In addition to temperature and humidity alerts, the Temp Stick wifi temperature sensors are also capable of letting you know when the battery level is low so they can be replaced before they die. It will also make you aware of an internet connection loss and continue to monitor and log data until it connects again, with a limit of 100 additional readings. An alert will also be sent out it reconnects.
WIFI Temperature Sensor Accuracy & Range
The Temp Stick has an extremely accurate wireless temperature and humidity sensor when compared to others on this list. It’s accurate to within ± 0.4°C in a temperature range of -40 to 125°F. On the humidity side, it’s accurate within ± 4% while between 0-100% relative humidity. Its actual operating range is 0-100% RH.
Temp Stick Setup
The Temp Stick setup process is easy and only takes 3 steps: 1) Insert the included batteries into the Temp Stick, 2) Connect to your cell phone, PC, or tablet, and 3) Sign up and follow the provided instructions to get started monitoring your temperature and humidity data. It only takes about 3-5 minutes to get started.
Temp Stick User Feedback
Current owners of the Temp Stick regularly comment on its easy setup and the intuitive app. Throughout our research, we’ve found very few complaints at all with the Temp Stick’s performance. In fact, those that have run into minor connection issues have even noted in reviews that Ideal Science has great customer service and support! Overall, existing and previous user feedback and reviews are very good for the Temp Stick.
Temp Stick Review Summary
If you need remote temperature monitoring for wifi that’s versatile, offers reliable readings, unlimited historical data, and includes remote alerts, the Temp Stick should be your top choice. As the maker says, “Be Anywhere, Protect Anything”. The only drawback we felt the Temp Stick had against it is that it takes readings at intervals between 1-12 times an hour. The user can choose the interval, but five minutes is the shortest span of time between readings, so you can’t actually see the real-time current data. For most this won’t matter, but be warned if you need the actual real-time temperature, this won’t work.
Connection Type: Wifi Temperature Sensor
Sensor Dimensions: 3.5” x 1.5” x 1.25”
Temperature Range/Accuracy: -40 to 125° C / ± 0.4° C
Humidity Range/Accuracy: 0-100% RH / ± 4%
Power Source: 2 AA Batteries
Battery Life: Approx. 1 year
SensorPush Review – “Best Remote Temperature Monitoring (multi-sensor solution)”
As far as wifi temperature monitors go, the SensorPush HT1 is very compact, yet full of features for the user. Because of its size, this would be my go-to option for tight space applications like inside a humidor, guitar case, or your refrigerator. The SensorPush HT1 runs by default on Bluetooth and works great while you’re within the house. If this is all you need, the SensorPush is a great, affordable option for you and tough competition for the Temp Stick. However, if you need to view the data remotely (out of Bluetooth range) while you’re away from home, or wherever the sensor resides, you’ll need to add some additional hardware.
Expandability & Accessibility
The SensorPush wireless thermometer can be paired with the add-on SensorPush G1 Wifi Gateway (sold separately) to remotely monitor the temperature and humidity from anywhere via the internet. Unfortunately, the gateway is not included with the SensorPush HT1, but the good news is that pricing is comparable with the Temp Stick even after it’s added. In fact, since there is no restriction to the number of sensors it can be connected to, the SensorPush option very appealing for multiple sensor applications. Similarly, there is no limit to the number of sensors that any one device can monitor, making it very accessible.
SENSORPUSH GATEWAY (SOLD SEPARATELY)
The SensorPush wireless thermometer is closer to providing real-time data as it can take readings every minute and log them with a time stamp. Most remote temperature monitoring devices take far less readings and really aren’t giving you real-time data. It will also display the data graphically or can be exported in a CSV file into an Excel spreadsheet for filtering and sorting.
Accuracy & Range
The temperature range on the SensorPush is – 40 to 140°F with a typical accuracy of ± 0.5 to 1.3°F, depending where you fall within the range. Note, this is the widest temperature range of all our wireless thermometer reviews. The humidity has a range of 0 – 100% with a typical accuracy of ± 3 – 4.5%. The wireless range on the sensor is up to 100 meter under ideal conditions and no obstructions. Real world examples could be less of course. The caveat the manufacture gives is a test they ran in a wood-framed, 2-story, 2600 square foot home, where the sensor could be read in virtually every corner of the house. Overall, the SensorPush accuracy is above average.
Much like the Temp Stick, previous customers that have used the SensorPush wireless temperature and humidity sensor have awarded it with very high marks. In particular, users love its compact size, accuracy, ease of use, and the amount of data this thing puts out. Specifically, many have commented that it works very well inside a humidor or guitar case because of its small size.
SensorPush Review Summary
The Sensor Push is the best selection in cases where you’ll be using multiple sensors, don’t need remote monitoring beyond the included Bluetooth connection, or if your need is in a tight spot. We highly recommend this remote temperature monitor, especially if your need falls within the requirements listed here. It’s affordable and compact and has received great reviews by existing users of the product.
Connection Type: Bluetooth is standard, Wifi w/ optional Gateway
Sensor Dimensions: 1.57” x 1.57”x 0.65”
Temperature Range/Accuracy: -40 to 140° F / ± 0.5° F (typical above freezing), ± 1.3° F (typical below freezing)

AcuRite 01166M Review – “Most Expandable Remote Monitoring System”
AcuRite 01166M Review:
Our next pick and review is on AcuRite’s 01166M 3-sensor remote monitoring package. The major strengths of this product are its expandability and versatility. The system comes with three temperature and humidity sensors, but is expandable with up to 10 total sensors or monitors that are sold separately by AcuRite. In addition, the system includes everything needed to remotely monitor each device via an app on your cell phone or tablet or on the web-based PC version. The free My AcuRite app allows for you to chart and/or graph your weather data and keep an eye on trends either hourly or daily. This insight can help you optimize energy efficiency through your heating and cooling system. Since it’s connected to the web via wifi, temperatures can be seen world-wide at the click of a button.
The three included sensors can be wall or table top mounted and can be located in different areas around your home. They provide large icons and numbers so you can understand temperature and humidity levels at a glance. In addition, trend arrows show if levels are rising, falling, or holding steady. The sensors are powered by 2 AAA batteries each. There is a bridge required with this setup, but it is included in the package as mentioned above.
Accuracy & Range
Temperatures are accurate on the indoor sensors within ± 2°F over a range of -4 to 158°F. Humidity is measured through the range of 1-99% and is accurate within 3-5%. AcuRite says the sensor range is up to 330ft, depending on construction materials. Inside homes and in real-world applications, users are reporting distances that are closer to 50-100 feet, depending on number of walls and if the hub is on another story of the house.
Alerts are sent to you via email or text message when levels reach preset conditions. This ensures you know immediately when something requires your attention or an action is needed.
As mentioned above, this system is expandable up to 10 total sensors/monitors. Sensor possibilities range from indoor or outdoor temperature and humidity sensors, water leak sensors, liquid and soil temperature sensors, rain gauges, and other weather-related sensors. The Smart Hub bridge can even be purchased with a remote monitoring weather station that gives you even more data than just indoor temperature and humidity, if that’s what you’re interested in. This package really could be just the start of a complete remote monitoring system that takes care of all your needs.
More users than not praised the 01166M as a good remote temperature monitoring system with lots of uses and even more potential. However, there are several that have provided valid complaints. First, a few have made note that this product is best suited for the US and Canada based on some of the functionality in the App. Additionally, we’ve noticed many customer issues with setup and/or complaints around longevity.
AcuRite 01166M Review Summary
The long and short of it is that this product has a lot of value for the user with three sensors and a great price. It’s also expandable to the point where other products on this list with 10 sensors would cost upwards of 10x as much as this one with that number of sensors. On top of that, this is one of the few products where you can actually see the readings on the sensors themselves if you’re in the room. With many other products, you need to go to the app to see the temperature of the room you’re standing in. However, product reviews are mixed, meaning there is some concern with the product’s performance. Our suggestion is to give this product a shot if it fits your needs, but make sure to buy from a reputable retailer in the unlikely event you have issues with the product and require an exchange.
Connection Type: Wireless Signal to Smart Hub, Ethernet Cable to Internet
Sensor Dimensions: 3” x 2.7” x 0.7”
Temperature Range/Accuracy: -4 to 158° F / ± 2° F
Humidity Range/Accuracy: 0-99% RH / 3-5%
Power Source: 2 AAA Batteries (each sensor)
Battery Life: Approximately 1 year
LaCrosse Alerts Mobile Review – “The Low-Cost Alternative”
La Crosse Alerts Mobile Review:
The next review on our list is the Alerts Mobile wireless monitor by La Crosse. This is a nice, compact product that measures both temperature and humidity remotely and uploads the data to the cloud via the included gateway. The gateway includes an AC adapter and plugs into the wall, while the sensor requires 2x AAA batteries that are not included. In addition, this weather-resistant gadget also comes with a dry probe (6ft) to monitor temps in hard to reach areas such as a freezer.
Setup for the LaCrosse Alerts Mobile takes place in three easy steps:
1) Connect gateway to your router (gateway & LAN cable included)
2) Add batteries to the temperature & humidity sensor and start sending data to the gateway
3) Login online or download the La Crosse Alerts mobile app & follow instructions to register
The beauty of this product is its price-point. It’s extremely affordable for allowing the user to do remote temperature monitoring via internet connection…but wait, there’s a catch. There’s always a catch! The text and email alerts are only free for the first three months. After that, you will need a subscription. At the time of this writing, an annual plan is around $12/yr. The info is in the manual you’ll receive with the product. I should make sure I clarify this; you can still see the readings remotely no matter what. However, you will need the subscription for the alerts.
Alerts that are provided are pretty comprehensive. They include presetting limits on both temperature and humidity, sending alerts when those levels are exceeded. In addition, alerts are sent when batteries are low or when the connection fails. According to the manual, the sensor uses 2 AAA batteries and battery life is estimated at 2yrs.
Accuracy & Range
The accuracy of the LaCrosse Alerts Mobile sensors do not appear to be published, although we did find the temperature range of – 4 to 140°F and humidity range of 3 -99%. La Crosse states that the wireless range of the sensor is up to 200 feet if installed in an open air area, with no obstruction. This is not common, and you should assume you probably will not get this kind of range if you are passing through walls, etc. Although the connection from the sensor to the gateway is wireless, the gateway must be placed next to your router and will be connected via the included LAN cable.
A big plus for the Mobile Alerts remote temperature monitoring system is that you can add additional sensors to the same gateway at a relatively low cost. They even offer compatible water leak sensors. The total amount of sensors that can be used per gateway is five.
There are more users that are happy with this remote home temperature monitor than there are users that aren’t. However, that being said, some existing customers have complained about trouble during installation and then hard to reach customer support reps through the manufacturer. In this situation, I encourage you to read through some of the reviews on amazon for yourself before buying.
La Crosse Alerts Mobile Review Summary
You simply can’t beat the price of this wireless remote temperature and humidity sensor. If your application needs don’t require high confidence in reliability, and cost is the driving factor in your decision making process for this need, the La Crosse Mobile Alerts temperature monitoring system will give you great value. Please keep in mind that if you require the alerts, there is a subscription service for about $1/mo, purchased annually.
Connection Type: Wireless Signal to Gateway, Ethernet Cable to Internet
Sensor Dimensions: 5.23” x 0.76” x 1.44” (w/ 6ft detachable dry probe)
Temperature Range/Accuracy: – 4 to 140° F / Accuracy Not Found

iHome iSS50 SmartMonitor Review – “Best Remote Temperature Monitor for Smart Homes”
iHome iSS50 Review:
The iHome iSS50 is an affordable smart home device that monitors 5 things at once: temperature, humidity, motion, light, and sound. It also provides real time push notifications to your smart phone to monitor your home remotely. The best part is that there is no hub, gateway, or subscriptions required to gain the benefits of this smartmonitor. Since it’s wifi-enabled, you can monitor the environment of your home from anywhere around the globe via an internet connection.
The smart monitor is compatible with Apple HomeKit technology and scenarios can be programmed to control automated triggers within your smart home. For this, you will need some extra hardware. For example, you can do IFTTT programming to tell something else to turn on if something the iSS50 monitors happens. This example would most likely require an iHome smartplug or smartplug with remote.
The biggest drawback of the iSS50 from iHome is that it must be plugged into the wall and has no battery capability. Along with its relatively large size, this really restricts where the sensor can be placed.
The iSS50 has a large, backlit LCD screen that displays status indicators as well as the current temperature and humidity. Luckily it can be dimmed from the back of the unit. The real hoopla of the iHome Smartmonitor is the amount of sensors it contains. You won’t find the breadth of sensors this model has on it anywhere else on this list. This, packaged with the smart home capabilities, make it a potentially powerful device.
I was not able to find any temperature or humidity accuracy or range specifications on the iHome iSS50 5-in-1 smartmonitor. The range of the sensor itself is limited to be near a wall outlet, but can be placed anywhere within your home wifi network area.
The iSS50 is good at providing real time data when you need it, however there is no real way to log or record data over time. This product doesn’t have the graphs and charts you’ll find on the best remote temperature sensor, or monitors.
Feedback from existing users is mixed to say the least. There are plenty of good reviews commenting about the affordability of the product and the number of sensors that you get. Unfortunately, despite the confusing advertising, most can only get automated triggers from the motion sensor in HomeKit (although it appears there is more functionality when using the iHome app itself).
iHome iSS50 Review Summary
This product is another inexpensive way to remotely monitor the environment in your home. It doesn’t appear that it is the most accurate, compact, or feature-rich product, but for the price tag, you can’t expect that. If home automation is your goal, this might fit your needs. If not, I’d grab something else from the list first. The idea is brilliant, however the execution leaves something to be desired. It just doesn’t appear to be ready yet.
Connection Type: Wifi
Sensor Dimensions: 2.6” x 2.3” x 4.2”
Temperature Range/Accuracy: Could not find
Humidity Range/Accuracy: Could not find
Power Source: AC wall outlet required
Battery Life: N/A (uses AC adapter)
Other Remote Temperature Monitor Options
There were other remote temperature monitor models that were evaluated and considered for this list, but ultimately deemed not a good fit for various reasons. Here are a few that were left off the list and general reasons why.
The Engbrid IBS-TH1 data logger is a cool device. Really, it’s similar to the idea of the SenorPush if there was no gateway option. The IBS-TH1 is a Bluetooth only device and is marketed towards the homebrew industry. There are a few features lacking on the Engbird product however. For one, there doesn’t appear to be a gateway option, so Bluetooth is it, meaning now remote monitoring when you’re not within 50-150ft of the product. It does have good accuracy, includes a temperature probe, and can be set to many different sampling intervals, including down to every 10 seconds. In addition, your mobile device can monitor multiple sensors, and each sensor can also be monitors via multiple devices. The CR2477 lithium battery lasts up to 1 year. Don’t let the comments you’ll see in reviews about it not being replaceable scare you. There are videos that can be found on Youtube that will help you replace it in just a few minutes. Unfortunately, without wifi, this temperature sensor just couldn’t climb our list.
Elgato Eve Degree Review:
The Degree has a very sleek design with a modern feel, however it runs exclusively on Bluetooth technology. In order to view data remotely, you’ll need a home-hub and additional smart home technology, which really isn’t want this list is about. It’s a “cool” product, but doesn’t fit what we were looking for here. If you have other Elgato Eve products, it probably makes sense to consider this model and you might find that it’s the best wifi temperature sensor for your home.
Although this remote thermometer and humidty monitor has decent customer reviews and good sensor accuracy, it requires an AC wall outlet at the point of the sensor. This means that it lacks virtually any portability. There is relatively little performance or customer feedback about this model on the internet at the time of this writing to compare, but we feel that the Temp Stick or SensorPush models above with their battery option are better options in most applications. For this reason, these wifi temperature sensors weren’t versatile enough to make the top of the list.
Room Alert 3 Wifi Review:
The Room Alert appears to be marketed towards IT applications such as a server room temperature monitor or similar for wiring closets, or critical rack cabinets. It really does give some great data and graphs for these applications. For the generic purposes of our list, it’s not our favorite option for remote temperature monitoring via the internet. It is powered with a 5v power adapter and didn’t have a ton of good customer feedback yet at the time of our evaluation.
The RCW-800 is a commercial-grade product and is suitable for pharmaceutical or food cold chain storage as a humidity and temperature logger, uploading data to the cloud. Just like the Room Alert above, this product is specialized and does not necessarily fit the generic applications that is the spirit of this best remote temperature monitor list. That’s not to say it’s not a good fit for the use case it’s called out for. In fact, if you are trying to remotely monitor temperature and humidity over wifi for cold food storage or a pharma application, it’s probably a good option.
MarCELL 500 Review:
The MarCELL 500 is a celluar-connected remote environmental monitor. In fact, in our opinion, it’s the best remote temperature monitor that uses a cellular connection. There are some major PROs and CONs to this product. Probably the most controversial feature is the fact that its connection is cellular. For some, this is a big benefit. If you don’t have access to wifi or another local internet connection, this might be your only option for viewing environmental data remotely. At the same time, the cellular connection means that it requires a subscription plan.
Other PROs for the MarCELL 500 are that it uses and AC adapter, but contains a battery backup so it should always be on and not require frequent battery changes. It’s also expandable and can use MarCELL water SPucks for leak detection (up to 16 per controller). Lastly, it does offer numerous readings and immediate alerts via text, email, or a phone call. On the CON side, it’s not portable since it must be plugged in and is relatively large in size.
Remote Temperature Monitoring Buyers Guide 2019
We’ve obviously done a ton of research above on the top rated products. So what do you need to consider when buying a wifi thermometer or wireless temperature monitoring system? There are several things to think about, but here are a few categories we suggest focusing on just like we did above in our reviews:
- Application or Use Case
- Connection Type (wifi, bluetooth, celluar, etc)
- Accuracy / Range
- User Feedback
- Alerts Provided
- Ease of Use / Install
- Data/Graphs Provided
- Power Source / Battery Life if Applicable
- Is Everything Included? Do you need other hardware to make it do what you need it to do?
Remote Temperature Monitoring Via Internet Applications & Use Cases
You’ll be surprised at the vast number of use cases there are for a remote home temperature monitor. Let’s look at some of the top reasons someone might need or desire such a device.
Second Home / Vacation Home / Cabin
Probably the most common use for these types of devices is a vacation home or cabin. You want to make sure that when you’re not around, nothing is negatively impacting your investment. A vacation home temperature monitoring system can catch all kinds of things like furnace failures if the temperature drops below certain levels or frozen/burst pipes if the humidity spikes. It could help you prevent mold growth or structural damage that costs many multiple times what the monitors cost.
Food Storage (Refrigerators and Freezers)
Most food types have specific safe temperatures at which they can be stored in order to keep them edible for human consumption. Outside this ranges, food can be dangerous to eat and make consumers sick, or worse. Food that requires cold storage requires special attention. Tracking these temperatures remotely and with preset alerts scheduled can ensure both the safety of the consumer and the investment of the food owner. Remote temperature monitoring via internet for this use is extremely important in commercial applications due to the sheer costs associated with the large volumes of perishable foods. The same can be said on a smaller scale at home. If you lose power or your deep freeze fails in the garage or basement without you knowing it, you could lose hundreds of dollars in food and make a huge mess! Utilization of a wifi thermometer can help you avert such a disaster!
Storage Lockers / Basements / Attics
Depending on what you’re storing and how valuable it is, it might be a good idea to have a remote temperature and humidity monitor. If you’re storing liquids, making sure they don’t freeze might be of importance. In addition, having a remote humidity sensor can help ensure you’re notified if conditions are optimalfor mold growth.
Of course we love our pets and want to keep an eye on them even when we aren’t there. It’s critical to both their comfort and their safety to make sure they are kept within a safe temperature range. Since we can’t always be at their side, remote temp monitoring with an alarm for when temperatures rise or drop out of the comfortable range would be nice to have. In addition to safety at home, of specific concern to those who travel. You might be comfortable that your home will stay warm, but what about an RV that is running off a generator? Traveling can be a time of great anxiety. Curb the nerves with an online temperature monitoring system that can provide you the alerts you need to feel comfortable that your loved pets are safe even while traveling remotely.
As most wine experts will tell you, certain wines are better when aged to peak quality. Aging is an art and a science and storage temperature and humidity are vital to this. Not only temperature, but temperature stability. Since most homes now have wifi coverage throughout, it’s become easy to connect remote temperature monitoring in wine cellars.
Cigar aficionados are big users of digital thermometers and hygrometers. The temperature, and maybe to a greater extent, the humidity at which cigars are stored affects their freshness. Too much humidity can cause them to become moldy, too little and they dry out. With the cost of some high-end cigars these days, you don’t want to take any chances. A compact product like the SensorPush wireless thermometer and hygrometer is perfect for this application.
Not unlike containers above used to keep cigars fresh, instruments are also contained in storage devices that should be monitored. Instrument storage, specifically for high-end guitars that can cost thousands of dollars, is important. Since components are made of different types of wood, they will expand and contract at different rates when temperatures change drastically, causing separation. Similarly, high humidity levels can cause a guitar to swell and change its tone. Whereas a very dry environment cause shrinking and cracking.
Server Rooms, Data Centers, and Other IT Applications
IT and other computing equipment causes a lot of heat generation. Most server rooms will have cooling systems to keep temperatures down. Overheating can damage to the equipment, or worse, start a fire. Remote temp monitoring can alert the manager if the cooling system is failing to do its job before it’s too late. For this reason, a server room temperature monitor is essential!
Temperature and humidity are both critical in hydroponics, the method of growing plants without soil. Different plants require different temperatures for optimal growing conditions. In fact, it’s common that different temperatures are required during the day than during the night. Additionally, too much or too little humidity can make pollination difficult. For this reason, a wireless remote temperature sensor and humidity sensor with wifi is a great asset for hydroponic growers
Remote Temperature Sensor Connection Type
Remote temperature monitoring systems come with all sorts of connection types. Most of the ones on our list above include a WIFI connection as the spirit of this list was to find something that allows for true “remote monitoring”. A remote temperature monitor with wifi like the Temp Stick offers the biggest benefit to the user in most cases. This is because the wireless range is usually adequate and by uploading the data to the web, it can be remotely viewed from around the globe. It’s also a wireless technology that allows the sensor to be portable in most applications, unless an AC adapter is required, which isn’t common.
Besides wifi temperature monitoring, some devices also use Bluetooth technology, cellular connections, and general wireless signals to a wired gateway that connects the sensor to your home network. The range on many Bluetooth devices can be limited and without additional gateways to send the information to the web, it can only be viewed locally. An example of this is the iHome iSS50. It still might be considered “remote” since it’s not always viewed on the sensor, and can also be viewed on your mobile phone or other smart device, but it must be within the Bluetooth range, eliminating functionality once you leave the home, unless additional hardware is utilized.
A generic wireless signal (433 MHz) is also used sometimes like in the case of the La Crosse Alerts Mobile. With this technology, there must also be a gateway device that allows the user to post information to the internet for remote viewing. This is the only way to view the data, whereas with Bluetooth, it can also be viewed locally on a mobile device while within range.
The last type of connection that is commonly used in remote temperature monitoring system is cellular. Yes, it’s the cellular connection you’re thinking of, similar to your cell phone. The benefit to a cellular connection is that it often has a very good range unless you’re in the middle of nowhere, however there is typically a large operating cost associated with this service that makes it unpalatable. There are some examples where having a cellular connection might make sense. Perhaps you can’t get internet easily in the area or if the internet connection isn’t used for anything else, perhaps the cellular subscription is actually more affordable. An example from above that uses this type of connection is the MarCELL 500.
If you read the reviews above, you saw that these sensors come in all sorts of sizes. For most applications, the smaller the better. We made sure to list each of the sensor dimensions on our list of best remote temperature monitors above. In the end, the best wifi temperature sensor is the one that fits your needs.
Sensor Accuracy & Range
This category is pretty self-explanatory. Depending on your use, accuracy might be important and it might not. For instance, if you’re concerned about temperatures right around freezing, being off by a degree might be of utmost importance. If you just want to make sure your furnace is still working, one degree here or there probably doesn’t matter. We’ve listed the temperature and humidity range of the sensors reviewed above when it was readily available.
When buying a home temperature monitor, there is always a trade-off between affordability and product reliability & quality. You obviously want to spend the least amount possible while making sure to get the job done. This is the reason we gave reviews on different options, hitting several price-points. Depending on your requirements, there are some remote monitors that are more reliable, but more costly, and others that are more affordable, but maybe not as reliable or accurate.
You’ll ultimately have to decide how important your needs are for an online temperature monitoring system. A good way to calculate the importance would be to determine what you stand to lose if you didn’t get the alert you needed to prevent a disaster. If you own a food distribution warehouse, it’s probably very important to get something reliable. A disaster in this case could cost you upwards of tens of thousands of dollars. The same goes for a vacation home temperature monitoring system if pipes freeze and burst in the basement. On the other hand, a half empty freezer or small cigar humidor might not break the bank if something fails.
This is one of the single, most important, things to consider when deciding on a gadget you’re somewhat unfamiliar with besides reading through our list, reviews, and buyers guide. Unless you’re looking at a product with just a few reviews, you can get a very good story about performance and longevity of a product through existing users posting reviews online.
Not all wifi thermometers are created equal. Depending on your needs, alerts might be critical to you and they might not be. Some common alerts that are included on these monitors include alerts for exceeding preset temperature and humidity levels, low battery, and failed connection. In addition to the types of alerts, a consumer also needs to pay attention to how often or how quickly they can be sent.
Ease of Use / Install
How easy is it to install the product? How about setting up the smart phone app? The Temp Stick is very easy to setup since it’s an all-in-one device and requires no external gateway device to connect to. Other wifi temperature sensors aren’t so user friendly. We tried to cover this aspect in each of our wiereless thermometer reviews above.
Data and/or Graphs
Although the iSS50 from iHome has lots of sensors and some other bells and whistles, it doesn’t log the graphs, history, and detailed data that most people are concerned with when they want to remotely monitor temperature and humidity. This is one of the reasons that it’s a nice device for a smart, automated home, but not for general, accurate temperature and humidity monitoring.
Power Source / Battery Life / Battery Recommendations
The power source of a wireless thermometer is a big one. We see that most sensors and monitors run on batteries, but there are many types: AA, AAA, CR2477, etc. Obviously, some are more readily available and affordable than others. Others devices are required to be plugged in, which really hinders mobility and portability.
In the battery operated devices, what is the battery life? We listed the manufacturer’s estimate for each of the monitors reviewed above. Battery life will affect how often they need to be replaced, how much money you’ll spend on batteries, and perhaps if you miss some readings. If your remote temp. monitor is at a 2nd home far away, you might not be there often enough to change the batteries before they fail.
What type of batteries should you use? For most moderate temperature applications, alkaline batteries work best. Conversely, lithium batteries work better in extreme temperatures, both hot and cold. If you will be using the remote temp. monitor in these applications, we recommend lithium batteries. Just make sure to get the right size! Not all remote temp. monitors use the same batteries.
Can more sensors be added? Can other types of sensors be added? For example, with the AcuRite 01166M, you can add up to 10 total sensors, including outdoor temperature sensors, leak detection monitors, etc. Before making a purchase, identify what sensors you’ll need, how many, and where you want to place them. Knowing this information up front will help ensure you choose the right system.
Is Everything Included?
There is nothing worse than being all excited about your new purchase and stoked about the deal you got, only to find out that you don’t have some expensive component you needed or a monthly subscription to a service. Keep an eye out for this with remote temperature sensors. We tried our best to make note of any additional gateways or subscriptions a product requires. Of course, as time goes on there may be changes to the products or services on the list. Always read all the detail of the product pages as well as customer reviews and feedback to see what surprises might be lurking.
Remote Temperature Monitor FAQs
Are these remote temp. and humidity monitors waterproof?
No, the remote temperature and humidity monitors on this list are not waterproof. There are special sensors for remotely monitoring the temperature of liquids. The AcuRite remote monitoring product line has sensors that are made for this purpose and include a liquid-sensing probe.
Would I be better off with a home weather station?
It depends on what you’re looking for. If you need a remote sensor to monitor the temperature inside your fridge or small humidor, then NO. If you just want to keep an eye on the indoor ambient temperature and humidity, then probably YES. For example, the Ambient WS-2902 Osprey has these capabilities and many others included, connects to wifi, and also gives you tons of outdoor data as well, and is actually price-competitive with the Temp Stick.
Will I regret buying a cheap wifi temperature sensor?
You might. As they say, “you get what you pay for.” Although it’s not always true, there is a correlation between the higher price sensors and the positive feedback from existing users on the higher rated monitors.
Where to buy the Temp Stick, SensorPush, and other remote temperature monitors?
Amazon has the widest selection of cellular, bluetooth, wireless, and wifi temperature monitoring systems. They are also a great source for customer feedback and product/sensor reviews. Last, but certainly not least, Amazon is very competitive and much of the time as the lowest prices on the internet. All of our product links for pricing and further reviews link out to Amazon.
Do remote temperature monitors take continuous readings?
No, most of the monitors on the list above take readings at preset intervals. Some are taken very often like every couple of minutes, whereas others might be set at every several hours, or even once per day. It really depends on what you’re needs are. If you don’t need more frequent readings, you might extend the battery life if you set it to take less frequent readings.
Final Notes On Remote Temperature Monitors
There are so many things to keep in mind when buying a wifi thermometer or any other remote temperature monitoring system. We tried our best to cover all the important topics and offer some common applications to give a better idea why you might need such a weather gadget. If you get the right one and set it up correctly, these devices are really cool tools that can help you avert disaster. They could save you from costly or irreparable damage to your home or sentimental goods.
On average, furnaces last 15-20 years. Odds are that if your furnace is close to this age, you are at risk of a failure. Without heat in the winter, pipes can freeze, leaks can happen, and mold can grow, etc, etc, etc. You get the point. With a remote temp. monitor, you’ll at least be alerted when something major happens as long as you set everything up right. WIth wifi coverage in most homes now, such these devices are easier than ever to connect and track.
Do you need or want to access more than just the temperature remotely? You can also get things like humidity, wind and rainfall data, and potentially much more, by just buying a wifi weather station. Of course these aren’t good options if you wanted to throw a compact temperature sensor in freezer or your guitar case, but are a great option if you just want the ambient temperature inside your house. For similar costs, you might be able to get the readings you need and a whole lot more!
