yesterday
A few years ago I bought a Google Nest Mini to control the lights in my bedroom which has worked great. Last year I expanded my lighting to the living room so bought another identical device to have one in my bedroom and the other in the living room to allow me to control the lights in both rooms.
The entire time I've had the device, it constantly resets every few days. It always seems to happen overnight (between 1am and 8am) and I'm unsure if it's exactly the same time or just somewhere in this period but has never happened during the day. There seems to be no pattern to how often it will reset sometimes going a few days with no issues and other times resetting every night.
Whenever this happens I'll notice when I try to use the device the day after and be told a series of different messages such as "I can't connect to the wi-fi network", "something went wrong" or more. Every time requires me to open up the Google Home app on my phone and most the time needs me to set up the device as new (add new device).
I've tried searching for other fixes and mostly seen about factory resets or trying a different plug socket, none of which have worked (and from the comments I couldn't see anyone with similar issues ever getting back saying theirs had worked either).
