Recently moved and after setting the same Wi-Fi network in the new home the camera, early models, all pair easily but none of 5 Wyze plugs will pair. Tried to delete on and go through the setup fails multiple tries!
Anybody…thoughts?
Did you do a full reset of the plug before putting it in Pairing Mode?

Also, before trying to pair, start the Wyze App, go to Account > App Settings and clear Cache from there. Restart your phone and then try to pair again, after doing the Factory Reset
These are my first thoughts, because I had a 
of a time with one last year:
If you click on the quote within the quote, that will take you to more detail about what I finally had to do to get a Plug (from 2019) back online. It’s still online and operational, too. 
Unfortunately I am trying to get these plugs unlike using an older IPad and an older non 5g capable router and then StarLink. No 5G anywhere in sight. I have done a factory reset, cleared cache in the app all to no avail!
