What type of device are you using to set it up (iPhone, Android..etc)? In the app on your phone, can you control things locally? If so, you need to make sure your password and account is linked properly with google. In the assistant settings, add the service again in the “works with google” section. If not, make sure your network password is correct, and youre using a 2g wifi with ONLY WPA2 security. If that’s correct, you might have to reset the devices and re add them completely in the Kasa app. Please let me know if any of this works.

Sorry for the delay in responding. 

 

I have verified I can control the plugs via the Kasa app while disconnected from my wifi. 

 

Oddly, this issue goes away when I am not connected to my wifi. Even though TP-Link Kasa is not listed as a connected service, the Google home app does show it connects to the plugs so long as I am not on the network. 

 

If I try to link Google Home to my Kasa account I get this error.
