This autonomous temperature and humidity sensor works perfectly. When connected to a Zigbee hub for remote control, it experiences continuous disconnections.

They do what they are supposed to without disconnections. I have 6 of these and in 5 months only 2 of them experienced disconnection twice. The accuracy of the temperature and the deviation that all 6 thermometers show between each other is minimal, around 0.2 degrees Celsius. Very reliable.

Communication with the Wi-Fi router is constantly lost and requires a restart. Also, I use it as a simple thermometer
