Frient Air Quality Sensor

meh I'm super cautious with the upgrades in winter season. My z-wave mesh sometimes go sideways after upgrade. :slight_smile: thanks for checking!
opened this topic to discuss my issue further. in case you interested. Frient Air Quality Sensor AQI issues

also one more thing I can think of, is the device firmware version. not even sure if its upgradeable. will research tomorrow.
