I’m using the Ring Doorbell 2 - Home Assistant have a “component” which links to their API…it brings with it, “doorbell press”, “motion trigger”, but only the “last recorded video”, no live stream is available via this API as far as I know. You also get things like WiFi signal strength and battery life too.
So currently, my trigger is the bell being pressed, HA detecting that, and then HA pulls the Hikvision feed for the driveway as a static image and sends it to the Fire TV via the “nfandroidtv” component.
I’ve no idea how the various components do all the clever stuff, i just know how to script it all in yaml to do what i want lol. If you wanted to try and explore more with the details, I’m sure if you posted on the HA forums they’d be helpful - the HA community is amazing…some really willing and clever guys there.
Regarding your second post - the FireTV is capable of displaying the Ring bell live stream, but only by using the utterance “Alexa, show me the front door” etc.
and as you know, the FireTV can display the Hikvision camera, via Monocle by saying “show me the driveway” etc.
My personal requirement, is to be able to load a camera stream via Monocle without having to do so via voice…if it was possible to create an Alexa Routine, which starts the monocle stream, that would be perfect, at least for my requirement anyway :)
