I’ve had this happen a few times now. My comcast connection goes down (typical) causing my SmartThings hub to disconnect. When the connection comes back up, my hub reconnects and then immediately my living room lights turn on for no apparent reason. They’re connected to a GE (Jasco) z-wave switch and I have an integration that triggers a couple of independent z-wave plugs when the switch is turned on or off. It would appear that the switch turns on after reconnect which also then turns on the outlets.
Nothing else in my house triggers or does anything weird like this. Is this a known issue at all? I haven’t been able to find any other information about it. Is there anything I can do to work around this? I don’t much care for my living room lights turning on in the middle of the night and staying on until I wake up and turn them off.
