@UditB,

I was reading through some of Google's forums about the matter protocol, and it seems to be a known issue. There is a forum thread where it is indicated that the problem may lie with the google play store not installing the matter package alongside the google home app. If you are familiar with ADB commands, you may try to follow this thread.

Some users indicated that installing another Matter-capable app, such as Alexa or Smartthings may install the package, and fix the Google Home App.

For my case, I had to  uninstall the Google Home App, and after reinstalling I was presented with entirely different options for setting up a matter-enabled device, and a bridge?; however I also currently have a few matter-capable apps installed.

Lastly, do you know if you are using the public preview interface for the Google Home App? If you are, the main page should have a button in the top left with the word preview in it, indicating that you have enrolled in the public preview program.

Hmm, I cannot think of too many things that would cause this, other than a Wi-Fi problem or something happening during a firmware update.

Honestly, I would recommend factory resetting the device and reconfiguring from scratch, as its possible the plugs updated and now have conflicting settings.

Since you think it may be a network issue, you may consider first attempting a soft reset (5sec), which will only restore the network settings to factory defaults.

Were the plugs only connected/controlled by the Tapo app, or are they also connected to another platform such as Google or Apple Home?

Two other things to try: move the device to another network such as your Guest Network, or isolate the device and see if the behavior continues. 2nd: Try different power outlets or test your power to make sure that they are receiving a stable voltage and not rebooting because of this.

Lastly, what model is your router from T-Mobile?

For Google Compatability, You should be able to control the device via Google Home's cloud connection to TP-Link servers by setting the device up in the Tapo App and linking your TP-Link and Google Accounts - it just will not be using a local matter connection. This can be done by either adding Tapo as a service in the Google Home App or through the Tapo App's Third-Party Integration settings.

For Matter Compatability, the device is compatible with the Matter protocol and should be accepted by any Matter controller hosting your network, whether Google Home, Apple Home, Alexa, or a Third-Party integration with Matter support. To use Matter with any device, you need to have one device on your network capable of being the controller, or brain, of your matter network. For Google this would be the Nest Hubs and I think their new streaming media player.
