I made reset for Fibaro Single Switch 2 device then readd it to ST hub, from this point it stoped to sync status. I still can to turn on the light and change settings (through both app and IDE) and it update settings on the device. But it always shows as Off in both app.
I thought that the problem is in switch so I deleted it from network. I have a new one single switch 2 device, after unpack, wire and add to the ST I have the same situation. So the problem in ST. Also the same devices added before this accident work well.
Any ideas how to fix it?
