What I'd really like to see is proper, cheap(ish) PoE IoT devices. I don't need everything to be wifi, I'd like to just run standard cable to everything, all on a secure common network, with power over the same cable. But PoE negotiation (chips) are apparently expensive, and eth chips more expensive than an esp.

Actually, maybe here's a (custom) solution: Run mains wires to an enclosure with one of these: https://www.olimex.com/Products/AVR/Development/AVR-IO-M16/ https://www.olimex.com/Products/AVR/Development/AVR-IO-M16/ And controlled & powered (the mcu, not the relays) via this: https://www.olimex.com/Products/IoT/ESP32/ESP32-POE-ISO/open-source-hardware https://www.olimex.com/Products/IoT/ESP32/ESP32-POE-ISO/open... Hence avoiding a separate esp board/mcu for every switch/device, and just using a single relay board for 4 at a time. Still a bit of a pain to drag mains to one location, might be better if this was individual relay boards with equipment wire running to each..
