Non-isolated ESP32-C3 boards that fit in a Ø60 wall box: a relay socket module that measures power with a BL0937, a two-channel TRIAC light switch, and a version of the switch without neutral that powers itself through the lamps. They connect to Home Assistant through ESPHome and have thermal lockouts. The KiCad projects, JLCPCB-ready Gerber/BOM/CPL and ESPHome YAMLs are free to download.
