My partner had a preference for the wider FOV so I got the black one. It paired no problem and after banging my head against the wall for a while I got the stream working in Home Assistant, VLC, then Frigate. I haven't decided how I want to handle the recording. I have yet to set up notifications and I'm not certain if my doorbell circuit is providing enough power, which would explain why the Bezos Bell sucked at keeping a charge (also surveiling your customers all day takes a lot of juice). This may become a slightly bigger project if I have to rerun the wiring.
There was a lot of hype around this bell and that naturally makes me skeptical, but rarely have I had a device pair and get to a functional state that quickly, even in most proprietary apps. We'll see how it works out once I have it wired in.
