I recently had all early wall plugs (6) go offline (and vacuum). Network connection was valid for other devices connected to internet. I believe it was due to app update 3.0?
The “fix” was to unplug the wall plugs for about 30 seconds and then plug them back in.
The vacuum required turning power off and then back on.
Just another pain in the ass for Wyze products. Hope this might help others with same problem.
This appears to be related:
It reminds me of an issue last summer where Wyze made a cloud change that affected the v1 Plugs, and part of the solution to get them back online involved unplugging them and plugging them back in.
