I was having the same issue as well. After a lot of experimentation I found that the issue was that pairing wouldn’t work when I had mobile data enabled on my phone. As soon as I disabled mobile data before starting the pairing process, all pairing was successful.
As an FYI, from my experimentation this is what I learned:
- WPA key length does not matter (I tried several lengths and nothing changed)
- Having an SSID that uses both 2.4GHz and 5GHz does not matter (I tried disabling 5GHz and nothing changed)
- Having the SSID broadcast or not does not matter (I tried both with broadcast enabled as well as disabled and nothing changed)
- If the phone is connected to 5GHz during the pairing, it doesn’t matter, as long as 2.4 GHz is available (I tried pairing with the phone on 5GHz but the bulbs connecting to 2.4GHz and nothing changed)
- As soon as I disabled mobile data on my phone, pairing always worked regardless of any of the above settings
I do not have Google Wifi but based my experimentation it wouldn’t appear to matter. I do have an Android phone. Not sure if these results are specific to my config. Perhaps a Wyzer (no idea if that’s what Wyze folks are called ) can comment. It seems like this should be able to be worked around in the setup or at least have the app check for this setting directly or indirectly.
Hope this helps!
