I’m working on building a home and have been investigating this seriously. I want to put multiple POE outlets in every room, and running them to places that are common for automation (eg for cameras, motion sensors, control displays, etc). I wish I could get wired sensors for doors/windows but the pricing is honestly way higher than just Zigbee with a battery once for factor in wires in the walls and a centralized patch panel.

I never thought about converting POE to USBC-PD but that would be a great thing to add to the “office” and locations where someone may very occasionally want power for a laptop (eg near couch, beds)

I’m exclusively using “normal” 120v outlets that also have a 5v usb port on it, and placing extra where I can, which is less crazy but still practical.
