Why my Zigbee devices keep failing?

Configuration Zigbee
1

I have a SONOFF Zigbee 3.0 USB Dongle Plus-E Gateway and a SONOFF SNZB-02 ZigBee Mini Indoor Temperature and Humidity Sensor. When I configured it yesterday it was working fine reporting temperature and humidity but surprisingly, today I woke up and no more values are being reported, and reconfiguring the device does not work, can I get some ideas?

Have you no other Zigbee devices, or is this the only one showing problems?

I do have some other devices like smart plugs and open/close windows/door sensors and they work fine but none of my SNZB-02 are working. The nodes not connected to the network are all SNZB-02

End devices often look unconnected on the “map” - it usually means they’re sleeping. Obviously something else going on in your case, though. Have you checked the GitHub device handler page for issues?
