I have 23 Devices in the home (All MOES 3-gang dimmer switches), and periodically over time, the switches will lose connection and be off the device list in Z2M. Went from 23 devices to 8 in 2 days. Also, walking around the house, have seen some in pairing mode randomly.
There might be something in here that will help.
Do you have any zigbee bulbs that are routing devices and on a dumb switch. That can cause problems.
So can your dongle not being on an extension cord, interference from a WIFI broadcasting on the same frequency, and other things.
