Just a note here in case someone runs into what I did yesterday. I had one of these working fine. Went to setup another and it looked like it paired okay. Hubitat saw it and it showed me sending on and off commands but the plug was not responding. I unpaired and paired it again and bingo it was working correctly then. Not sure what happened on the device side and the logs looked okay but it wasn't working for sure until it was paired again.
Love the power reporting on this. For me it works better than the Zooz power reporting does.
