Welcome to the Forum, @nguyen.michael17! 
Bump away! This is what old topics are for! 
I suspect something has gone goofy on Google’s end with this one. I’ve had my Video Doorbell v2 disconnected for a while, but I just tried to set up a Wyze Automation (using a Cam v4’s Motion Detected event to trigger a Plug) and a Google Home Household Routine (using the Plug turning on as the Starter), and I currently can’t get it to work. In the Google Home Routine’s Actions section, I’ve used the “Custom command” option and have tried things like…
- Stream {my camera’s name}
- Show {my camera’s name}
- Show {my camera’s name} on {my Hub’s name}
…and I have the Hub selected as the “Play on” device in the Configuration section. It’s just not working.
I can talk to Google Assistant on that device and say, “Stream {my camera’s name},” and the camera streams when I do that, so things like that work, but the Automation isn’t getting it done for me.
In another recent topic, there was mention about how trying to select a Wyze Cam to stream in the Google Home app now results in a prompt from the app about Nest devices which seems like kind of a useless and annoying roadblock. I don’t know if that’s directly related, but it seems like more evidence that Google has been doing things on their end and probably broke (intentionally or not) Wyze Cam streaming from Automations.
