My doorbell is a raspberry pi that uses webhooks to send me messages on my privately hosted chat server and also rings a physical bell built in 1900. Do I win for the most simple high tech doorbell?

    So you can ring your doorbell if you're in vacation on the other side of the globe?

    Yep, with curl because I have OliveTin setup to accept requests to ring the bell from other pis or myself if I feel the need via the web GUI.

    Oh that's a silly question. Why not?

    The honest answer is in the US all doorbells are powered by simple 24VAC transformers that burn 6–7 watts just being powered up, forever, for decades. This annoyed me plus I wanted a fun bell so I wired up a pi to use a modern, efficient 24VDC power supy to ring the bell and it gets turned on by the pi only when its needed so now my idle wattage is more like 0.25W.
