AcuRite Atlas™ (7-in-1) Shows Inaccurate Temperature or Humidity


If your AcuRite Atlas™ (7-in-1) High Definition Display or My AcuRite™ account is showing the incorrect or inaccurate outdoor temperature or outdoor humidity readings from your AcuRite Atlas™ (7-in-1) Weather Station, please review the troubleshooting suggestions below.

These steps may also be performed if you are seeing the following error codes:

  • -40 degrees 
  • 158 degrees
  • 1% humidity
  • 99% humidity


 You would want to ensure the following first:

  1. Please verify that the AcuRite Atlas™ (7-in-1) sensor is located away from sources of heat and moisture. Nearby bodies of water may have an effect on the accuracy of the humidity readings.
  2. Make sure that the AcuRite Atlas™ (7-in-1) sensor is mounted at least 5 feet off of the ground or any other surface that may radiate heat. Roofing materials such as shingles or metals can radiate heat and affect the temperature readings of the AcuRite Atlas™ (7-in-1) sensor. 
  3. The National Weather Service recommends mounting the sensor 33 feet above the ground with no obstructions within 100 feet for the most accurate readings. We understand not all of our customers can mount this high. You should receive an accurate reading for where it is mounted. If you are comparing to a local news station, they typically follow the National Weather Service guidelines.
  4. Ensure that your display unit has connected to the correct sensor. If a neighbor also has a compatible sensor within range of the display, it may have connected to their's instead. Please make sure that the channel designation that you have physically set your AcuRite Atlas™ (7-in-1) sensor to matches the sensor that the display unit has connected to. You may need to change the channel designation that you are using by performing the hard reset below when pairing to the AcuRite Atlas™ (7-in-1) display. 


If readings are inaccurate or an error code is displayed:

  1. Please remove the batteries from the outdoor sensor.
  2. On the bottom of the AcuRite Atlas™ (7-in-1) sensor, there is a vent cover that is held in place by 2 tabs. Remove the vent. Under the vent, there is a cylinder that is clipped in with 2 tabs. This is the temperature and humidity sensor. Remove the temperature and humidity sensor to expose the fan.
  3. Unplug the white cable connector and wait 20 seconds then plug the temperature and humidity sensor back in. This will reset the temperature and humidity readings. 
  4. Install the temperature and humidity board over the fan assembly, confirm the tabs do not block the fan from spinning.
  5. Reinstall the batteries in the AcuRite Atlas™ (7-in-1) sensor.  Confirm the red light near the battery compartment door flashes every 10 seconds.

If you are pairing to the AcuRite Access™ Model 09155M, allow 5-10 minutes for the dashboard to update. (How do I Check the Last Time the Sensor Updated?)

If you are using the AcuRite Atlas™ (7-in-1) display model 06061M, you may need to perform the hard reset below.


Hard Reset:

Please follow the steps carefully as the order is crucial to the success of the reset. This will clear all historical data.

  1. Bring both the sensor and display unit indoors and position them side by side.
  2. Remove the batteries from the sensor and change the sensor to a new ABC channel. 
  3. Go to the main menu by tapping the "MENU" button.  The "MENU" button is the three white horizontal lines in the upper left-hand corner of the display.
  4. Tap the "Sensor" option from the menu. 
  5. Tap "Remove A Sensor". If the display shows you a picture of the AcuRite Atlas™ (7-in-1) sensor, Tap "Done" (If the screen does not change/the remove a sensor button does not work, skip down to step 8). 
  6. It will ask you to confirm removing the sensor, tap "Yes".
  7. It will ask you "Are you sure?", tap "Yes".
  8. The display will revert back to the previous screen. Tap the back arrow in the upper left-hand corner of the display to return to the main menu.  
  9. Tap "Factory Reset".
  10. You will receive a prompt asking if you want to reset to factory settings. Tap "Yes".
  11. It will ask you "Are you sure?", Tap "Yes". The display will reset itself and go to the main AcuRite logo screen. 
  12. You will now be able to set up the display by following the on-screen prompts. 
  13. Once that is completed, put the batteries back into the sensor directly. (Follow these troubleshooting steps without the use of a battery pack and/or power adapter.)
  14. Go to the main menu by tapping the "MENU" button.  The "MENU" button is the three white horizontal lines in the upper left-hand corner of the display.
  15. Tap the "Sensor" option from the menu.
  16. Tap "Add A Sensor".  
  17. The display will look for your sensor and show a picture of it when it is found asking if you would like to add it. Ensure that the designation in the description matches the channel that you set your sensor on.  Tap "Add This Sensor".
  18. The display will revert to the previous screen.  Tap the back arrow in the upper left-hand corner of the display twice to return to the main screen. 
  19. Let both sensor and display sit side by side to establish a connection. (Leaving the units side-by-side for 30 minutes will allow you to verify accuracy by comparing the indoor and outdoor readings shown on the display.)
  20. After a connection has been established, the sensor can be placed outdoors.
