That looks great. The 0-70C operating range is noteworthy if you want to use it for a doorbell, though.

- waste_monk 3y agoIf you're worried about sub-zero temperatures, couldn't you just have it busy-loop or even drive a small heater to generate heat? Just enough to keep the doorbell enclosure warm. If it's running off PoE it's not like you have to worry about battery budget or efficiency so much. Not sure if there are insulating materials available that provide good thermal insulation but not acoustic insulation?
