First, I’m happy to report that the stream did show on a Lenovo Smart Display. About 10 second delay after command for it to start the feed, and about 15 second delay between the live activity and the camera feed.
I was able to have one camera feed on the Lenovo hub and a different feed on the Chromecast at the same time.
The picture on the 55" tv looked pretty good through the CC.
“Turn off the camera” doesn’t stop the feed… It powers off the camera. I was able to power it back on using hub touch display.
I assigned the cameras to rooms, and when I asked the hub to show me the room, it pulled up icons for the camera, my Google speakers, and smart bulbs assigned to that room.
When I asked it to show me the (groupname) cameras on (Chromecast), it said it was showing both cameras in that group, but only one feed showed on screen. I tried to get it to go to the next camera, but it didn’t understand.
