If your AcuRite Atlas™ (7-in-1) High Definition Display or My AcuRite™ account are reporting low or inaccurate UV or light intensity readings from your AcuRite Atlas™ (7-in-1) Weather Station, please review the suggestions below. These steps can also be used if your AcuRite Atlas™ (7-in-1) Weather Station is not reporting any UV or light intensity readings.
Check the sensor for debris. Use a damp cloth to wipe away any buildup on the UV and light sensor. Below is a photo of the location for the UV and light sensor.
Confirm the sensor is not located in a fully shaded area. The UV and light intensity readings may be lower on a cloudy day or if an obstruction is blocking the sunlight from directly shining on the sensor.
Confirm the red light near the AcuRite Atlas™ (7-in-1) sensor's battery compartment flashes every 10 seconds and the AcuRite Atlas™ (7-in-1) display unit maintains 4 bars of signal strength. (Wireless Signal Strength Indicator)
If monitoring from the My AcuRite™ Dashboard, confirm the sensor is online and updating (How do I Check the Last Time a Sensor Updated?)
