How to Calibrate Acurite Notos Weather Station Sensors

You can calibrate the indoor/outdoor temperature and humidity readings, and barometric pressure on the display to improve accuracy. Just like with a Lacrosse View, calibration can improve accuracy when sensor placement or environmental factors impact the accuracy of the data.

  • Press and hold the up arrow button, Settings button, and down arrow button simultaneously for at least 5 seconds to access calibration mode.
  • To adjust the currently selected (flashing) item, press and release the up or down arrow buttons to calibrate the data value higher or lower from the actual reading.
  • To save your adjustments, press and release the Settings button to adjust the next preference. The “spanner” icon will remain illuminated next to the calibrated values.

The preference set order is as follows:

  • OUTDOOR TEMPERATURE
  • OUTDOOR HUMIDITY
  • INDOOR TEMPERATURE
  • INDOOR HUMIDITY
  • BAROMETRIC PRESSURE (it must be set to MANUAL mode to calibrate)

To change from AUTO to MANUAL pressure mode and vice-versa, press and hold the Settings button for at least 10 seconds. The display indicates the current pressure mode selected, “AUTO” or “MANUAL”.

After 20 seconds of inactivity, the display will save the adjustment and exit calibration mode. Note that calibration will be erased if you reset the display or if you remove the batteries and unplug the power adapter.

Why is My Acurite Weather Station Flashing?

Flashing of the outdoor temperature in Acurite Notos may be an indication of wireless interference. To fix this:

  • Make sure the A-B-C switch in the battery compartment of both the display and sensor are switched to the same letter.
  • You may choose A, B or C, but both units must match to synchronize.
  • Sometimes changing to a different channel can help.

If the light on the front of the Acurite Access is flashing red there is no network connection. The Acurite Access front light will remain solid blue.

To troubleshoot:

  • Make sure the Ethernet cable is firmly connected. The cable may be defective and need to be replaced.
  • Check your network router settings. Make sure DHCP is enabled on your router, MAC address filtering is disabled, port 80 is open and priorities are turned off.
  • The Ethernet port of your router may be malfunctioning. Try connecting the cable to a different port.

Acurite Notos Outdoor Sensors Not Working

If your weather station is having any of the issues below, these are symptoms of the sensor not connecting to the display:

  • Outdoor temperature not changing.
  • No outdoor temperature (showing dashes).
  • Inaccurate wind speed or no wind speed
  • The outdoor humidity reads 1%
  • The outdoor temperature is -40 degrees.

 To resolve the problem, you would want to ensure the following first:

  • Verify that the A-B-C switch in the battery compartments of both the display and the sensor are set to the same letter. You may choose A, B, or C; but both units must match to sync up.
  • Relocate the display unit and/or sensor. Under optimal conditions, the units can be located up to 330 ft of each other.
  • Units should be placed at least 3 feet away from electronics like microwaves, TVs and computers among others, that may interfere with wireless communication.
  • Use standard alkaline batteries (or lithium batteries in the sensor when the temperature is below -20oC/-4oF. Note that it may take approximately 5 minutes for the display unit and sensor to sync after batteries are replaced.

If after the above steps you are still getting no wind speed or the wind speed is inaccurate, perform a hard reset as per the steps given above.

Acurite Notos Weather Station Searching for Sensor

If the wireless signal indicator shows no bars, try the following troubleshooting steps to resolve the issue:

  • Relocate the display and/or 3-in-1 sensor. The unit must be with 330 ft (100m) of each other.
  • Make sure both units are placed at least 3 feet (.9m) away from electronics that may interfere with the wireless communication.
  • Use standard alkaline batteries (or lithium batteries in sensor when temperature is below -4oF/-20oC).
  • Do not use heavy duty or rechargeable batteries. Note that it may take a few minutes for the display and sensor to sync up after batteries are replaced.
  • Synchronize the units:
  • Bring both the sensor and display indoors and remove at least one battery from each.
  • Make sure the A-B-C switch on both units match.
  • Reinstall the battery in the outdoor sensor.
  • Reinstall battery into the display.
  • Let the units sit within a few feet of each other for a few minutes to gain a strong connection.
