I just has to change up my Internet and WiFi setup in my business and my smart plugs and switches were no longer connecting to my guest WiFi. I had to remove everything and use a different WiFi (normally I just replicate the ssid and passphrase) now not everything is adding back Google home, and what is there is not functioning properly.

Currently I have plugs and a switch from Kasa, a switch I use through smart life app, and lights from Avatar.

Is there a smart home app that will link all of them the way Google home did?
