The idea of live-view-only-access makes me think of what household members in the Google Home app have with the Wyze cameras I’ve linked to Google Home. That’s all they get. Unfortunately, Wyze’s integration with Google Home (and/or Google’s ability to consume and display the Wyze camera feeds) can be spotty at times, so sharing through the Wyze app is a more reliable way to allow others to view what the cameras see.
I haven’t taken the time to do that, either, and I don’t think it’s necessary for the average user to read back through 5½ years of posts. I think the list in the immediately preceding post and the poll attached to the initial post seem like good starting points, and maybe someone on the app development side will get on the stick and assemble a list of potential user/permissions features to add and post something akin to what the Rule Team did recently.
Something I’d personally like to see on such a list would be giving users control of what notifications to receive. If I want to receive all sound and motion notifications for a camera and also share that camera, the person I share it with might not want to be bothered with the same notifications.
