AcuRite Notos Review: Which 3-in-1 Version Is Best?
Notos is AcuRite’s simple local weather-station family: one 3-in-1 sensor for temperature, humidity, and wind speed, paired with five current display styles. The omissions matter as much as the features.

Five current Notos versions, one outdoor sensor
AcuRite’s current Notos collection lists five bundles. The model numbers can look like five different stations, but the outdoor measurements are identical. All use the 06008M/06008RM sensor. The console supplies indoor temperature/humidity and barometric pressure, then combines pressure and sensor data for forecasts and derived values such as wind chill, heat index, and dew point.
| Current AcuRite bundle | Display | Best reason to choose it | Watch for |
|---|---|---|---|
| 00589MCB | Light-theme illuminated color display | Readable overview, adjustable dimmer, Weather Select, wind low/average/peak, pressure trend and 12-hour history. | AC-powered; optional six-AA backup. Amazon title may use 00589M. |
| 00622MCB | Reverse-color/dark display | Current, peak, and average wind plus a 12-hour chart that can toggle pressure, temperature, or wind. | Larger 7.7-by-7.1-inch console; optional six-AA backup. |
| 01604A2 | Narrow vertical Pro Color display | Compact footprint, moon phase, Intelli-Time, forecast, and daily/all-time records. | Tabletop only; Amazon commonly labels the retail version 01604M. |
| 00638A4 | Digital monochrome, first generation | Battery-powered local display with atomic clock, moon phase, and 12-hour history. | Current AcuRite SKU ends A4 while Amazon titles may show older revision 00638A3. |
| 00634A4 | Digital monochrome, second generation | Simple battery-powered console, atomic time, moon phase, and history. | US time zones only; Amazon may show revision 00634A3. Confirm exact seller/listing contents. |
Notos Amazon options
AcuRite Notos 00589M / 00589MCB
Choose the light-theme console for the most approachable all-at-once view of indoor/outdoor temperature and humidity, wind, derived conditions, pressure, and forecast.
Confirm the bundle includes the 06008M sensor and light-theme display. Display-only and replacement-sensor listings are separate products.
AcuRite Notos 00622MCB
Choose this version when the reverse-color screen, wind peak/average/current views, records, and selectable 12-hour history chart matter more than a light background.
Match model 00622 and the dark/reverse-color display; visually similar AcuRite consoles are not interchangeable.
AcuRite Notos 01604M / 01604A2
The narrow vertical display uses less counter space and adds moon phase, Intelli-Time, forecast, and record views while keeping the same outdoor measurements.
AcuRite’s current bundle SKU is 01604A2; the Amazon title may use 01604M. Confirm the pictured vertical display and included 3-in-1 sensor.

Placement is Notos’s biggest practical compromise
The same compact body makes installation easy and ideal exposure impossible. Wind speed benefits from height and a clear fetch. Temperature and humidity are best measured over representative ground, away from reflective surfaces, and typically lower than a wind sensor. Notos forces one height and one location for both goals.
For everyday backyard conditions, use an open location over grass, keep the unit upright, and avoid roofs, walls, pavement, dryer vents, air-conditioning exhaust, and irrigation spray. A shaded or naturally ventilated exposure reduces direct-sun bias, but do not tuck the unit beneath dense trees or an eave just to create shade; that can shelter the wind and trap moisture. Follow the mounting manual and judge comparisons only against sensors with similar exposure.
- Wind reads low: check shelter and height before blaming the cups or applying any correction.
- Temperature reads high in sun: inspect nearby heat sources and airflow; Notos uses a passive shield, not an aspirating fan.
- Humidity differs: compare colocated sensors long enough to account for response time and normal tolerance.
- Signal drops: shorten the path, move the display away from interference, and remember that 330 feet is an ideal maximum.
What Notos does not measure
This is the section many quick reviews skip. Notos does not directly measure rainfall, wind direction, lightning, UV, solar radiation, or outdoor barometric pressure. The indoor display contains the barometer and calculates a 12–24-hour forecast after its learning period. Wind chill, heat index, and dew point are derived values, not extra outdoor instruments.
AcuRite’s learning mode begins with a standard pressure assumption and refines local pressure over time. The icon disappears after 14 days, while AcuRite says the underlying running calculation continues for roughly 33 days. Resetting or depowering some displays can restart the process, so do not judge the forecast on day one.
Display features that are calculated indoors
Every Notos display can show more than three numbers because it has its own indoor sensors and software. Depending on the version, you may see indoor temperature and humidity, barometric pressure and trends, a personalized forecast, wind chill, heat index, dew point, moon phase, records, clock/calendar, and history charts. These are legitimate features, but they should not be confused with additional outdoor sensors.
Notos vs Iris, Atlas, and Optimus
| Family | Outdoor measurements | Best reason to choose it |
|---|---|---|
| Notos | Temperature, humidity, wind speed | Lowest-cost simple local weather station; five display styles. |
| Iris | Adds rain and wind direction | Better minimum feature set for a true backyard weather record. |
| Atlas | Adds rain, direction, UV, light; optional lightning | More capable and modular hardware with aspirated temperature sensing. |
| Optimus | Adds rain, direction, lightning | Compact current app-first system with Wi-Fi displays and limited lifetime warranty. |
Pros and cons
- Simple setup and one compact outdoor sensor.
- 18-second transmissions are responsive for casual monitoring.
- Five current display choices cover light, dark, vertical, and battery-powered preferences.
- Useful indoor pressure, forecast, record, and derived-value features.
- Replacement 06008M sensor remains documented and available.
- No rainfall or wind direction—the two omissions most buyers eventually notice.
- No built-in Wi-Fi or included phone access in the current display bundles.
- Passive temperature shield and all-in-one placement compromise.
- One-year warranty is shorter than Optimus’s limited lifetime coverage.
- Marketplace revision numbers can differ from current AcuRite SKUs.
AcuRite Notos FAQ
Does Notos measure rain?
No. The 06008M/06008RM sensor measures temperature, humidity, and wind speed only. Move up to Iris, Atlas, or Optimus for rainfall.
Does Notos show wind direction?
No. The sensor has wind cups but no vane. Direction cannot be added by choosing a different Notos display.
Which Notos version is best?
00589MCB is the easiest recommendation for its readable light-theme overview. Choose 00622MCB for a dark screen and deeper wind/history presentation, or 01604A2 when a narrow display matters most.
Can Notos connect to an app?
Not directly through the ordinary current display bundles. AcuRite documents separate Access compatibility for the sensor, but buyers should verify current Access hardware and platform support rather than assuming it is included.
How long does the forecast take to calibrate?
The learning icon disappears after 14 days. AcuRite says the algorithm continues refining its running average for about 33 days.
Are 00638A3 and 00638A4 the same listing?
They are retail revisions in the same first-generation display family, but do not assume identical contents. AcuRite’s current store uses 00638A4 while Amazon titles may show A3; confirm the exact model, sensor, and display pictured.
Bottom line
AcuRite Notos is honest, useful, and limited. It is a good first station when your real question is “what are the temperature, humidity, and wind speed in my yard?” It is a poor buy when you are already curious about rain totals, wind direction, phone access, or future expansion. Among the current versions, 00589MCB is the best default; 00622MCB is the stronger enthusiast-style display; 01604A2 is the space-saving alternative. If the missing measurements matter, skip the display debate and move to Iris or Optimus.
Best balance of readability, weather context, records, and straightforward local use.
