Hi @klkeefer, if this is your new sensor, then this is due to the registration settings. Your sensor is currently registered with the LED Mode set to “Off, NO LED’s” and the LED Brightness set to zero. To turn on the LED ring, you’ll need to update your sensor’s registration, and change these settings to the values below:
- LED Mode will need to be set to either “Power, SD Status and Full Color AQI” or “Full Color AQI Only”. Full color AQI refers to the LED ring.
- The LED Brightness (%) will need to be set to a nonzero value. The default value is 35.
