@R.Good is right that this ability isn’t NATIVELY available solely through Google Home or Wyze alone, however, there IS now an easy workaround thanks to some recent Google Home updates this summer! I can give you step-by-step instructions to make this happen exactly as you’re requesting.
For a V3 camera (which you tagged into this thread, so I’m going to answer related to the V3), what you would do to make this work is the following:
In the Wyze app, create a new rule for that V3 Cam, let’s say that camera’s name is “Front V3” :
- Create Rule
- Device and Service Trigger Rule
- If (select Device and Service Trigger) → Select “Front V3” (or name of cam) → Select “Detects a Person” (or Detects Motion)
- Save Trigger
- Add Action → Front V3 (or name of actual cam) → Turn on the camera
- Save Action
- Save Rule
Now, what the above does is it makes Wyze send an “On” Command to the camera through the Wyze server. Your camera is already on, so basically the command doesn’t impact the camera at all because it was already on. So nothing bad happens. But NOW we can have Google Home recognize that an “On” command was sent to that camera, and tell Google to do an action whenever it sees that on command to that camera on the Wyze server. So now lets go setup Google to do what we want it to do!
- Open Google Home
- Select the Automations tab
- Select the “+ Add” Button on the bottom right
- Select Household
- Select “+ Add starter”
- Select “When a device does something”
- Select “Front V3” (or whatever the name of the cam is)
- Select “Turns on or off” then “Turns on” then “Add Starter”
- Select “+ Add Action”
- Select “Try adding your own”
- Type in the command you want it to do, such as “Show Front V3 on Living Room Display” (This is assuming your Google Home Hub is named “Living Room Display”…if not, change “Living Room Display” for whatever your Google Hub Device’s name is).
- Save
Now go test it out. Walk in front of your V3 cam (or have someone else do it), and as soon as it detects a person, it should send the “On Command” which Google will see and then start the stream command to your Hub. Now it’s working just like you asked with a little smart ingenuity.
Now you can do the same for almost any of your other cams by doing the same thing…
Doorbells are the only exception. Wyze doesn’t have an “On command” available for a Video Doorbell Cam, so if you wanted a Doorbell to do it, you would have to tell the doorbell to send a “Turn on” command to a different camera (or other device like a plug) instead. Then it will still work for a Video Doorbell too. I have asked Wyze to please add an on/off command to their Video Doorbells to make this easier for those too. But either way this trick should work for any of your cameras to automatically stream to a Google Hub. Pretty cool stuff. I plan to have a Google Hub dedicated to do this for a couple of my outside cams.
Let me know if you get it working, what you think and if you have any questions. I hope that helps!
