I, i’ve installed a SonOff Dongle, Mosquitto Broquer and Zigbee2mqtt.
I think all went wright and i’ve added (with success) my first device to test. It’s an Xiaomi WXKG01LM.
The problem is that i can’t obtain any status of it and also tested a simple automation (turn on light) to check if it is opperting despite it’s not showing the enteties status, but with no reaction.
I’ve already overcome the issue and i’ve installed 3 switches.
1 is a doble switch from xiaomi that works 90% of the time (sometimes it doesn’t trigger the automation).
But, i have another 2 simple buttons from Xiaomi also and after i join them to zigbee2mqtt they work, but after 1-2 hours they no longer work.
If you only have a coordinator and 3 switches, it can be because you have a poor mesh. Adding something mains powered (mains powered zigbee devices act as routers) can help to improve the mesh.
