Are you able to successfully link your Yi cameras account to your Google Home? If not, are you getting any message? Make sure your devices are connected to the same network and within 15-20 feet of your router. Also, reinstalling your apps might help too.
Keep us posted.
I get a message saying there was no compatible devices. All may cameras used to be compatible but all of the sudden, it no longer worked. I tried to unlink and link it again but there's no more devices compatible
Understood. Do you have other smart devices connected to your Google Home? If so, can you control it using your speaker? Try removing and adding your devices from its native app. Resetting your speakers might help too. If the issue persists, we'd suggest contacting your camera manufacturer for additional assistance.
I wanted to follow up and see if you are still in need of any help. Let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.
Thanks for the update! Glad to know that it's working!
