SONOFF AirGuard TH Lite Zigbee Temperature Humidity Sensor | SNZB-02B

works great

Great product! I use it in my wooden storage cabinet to monitor the environment. It reminds me when the temperature and humidity are not ideal, helping me avoid mold issues.

Sonoff Temperature/Humidity devices

All of my Sonoff Temperature/Humidity devices are in sync! The SNZB-02B is working perfectly from inside my freezer!

Doesn't update regularly. Frequently loses connection. Suggested app (eWeLink) is terrible with bad design and missing features. App does not fit within the phone screen, leaving some areas hard to click on.
