We have a few of the Deta smart switches from Bunnings which we've had for around a year and a half now. Sporadically they will reset of their own accord - I had one particular switch reset 3 times in the last 3 weeks.
They will work ok for weeks/mths at a time but occasionally drop out. When they drop out, the Grid Connect app reports "Room 1 light switch has been removed from "Location" due to device reset". We also get a google notification on our phone saying something to the effect of "[email protected] has unlinked XX light switch from your home". The switches then require re-pairing to the wifi network/Grid Connect app and then we have to go back into the Google Home app to set up our "routines" (allowing specific light scenes) all over again. This is inconvenient and gets tiring after a while and is preventing us from upgrading more of our home switches.
Thinking it might be a bug with these switches, has anyone else had a similar experience? I've updated the firmware on all of them which btw for anyone else that uses these switches, the latest FW enables the little indicator light to remain lit which is really handy for finding the switch at night.
My grid connect downlights like to occasionally reset themselves. Same as you, every few weeks. I will come home and my lights will be in reset mode. Fun times.
