Cameras are not included in Matter for the moment but there is no reason why they can’t be in the future but right now, I’m not aware of any work in that area.
For the integration, a matter compatible devices will be able to enable Matter enabled ecosystems. So SmartThings is saying, that they will enable their ecosystems with Matter. Matter devices should be able to join multiple Matter ecosystem at the same time.
I guess there is enough in Matter to do a full livestream session but for the devices to be Matter compliant, there are multiple ways: But for Wyze Sense Sensors, we can make the new hub Matter compliant and use it as a bridge/gateway. There is a provision in Matter to do just that. Since we are using the same processor than the camera (not ESP32) and it is not supported by default by Matter, we would have to recompile the entire Matter SDK to make sure it is working properly. It should be easily doable since it is using Linux Embedded if my memory serves me correctly.
