Here’s the main thread discussing Yi Home camera’s and their potential for ST integration. This would be the best place to post any further questions about this.
The long and short of it is that these camera’s can be integrated into ST with two big caveats. 1. You need to install a hacked firmware that exposes your camera’s video feed via RTSP. 2. You need to use an external video recording software like Blue Iris. Those caveats have been a big enough barrier to keep me from taking the plunge.
