PIR occupancy sensors using NodeMCU, ESPHome, and Home Assistant

The beginnings of a DIY security system and occupancy sensor network. I repurposed an existing and defunct Bosch Solution 880 security system, reusing the existing sensors and wiring. Be careful if you are doing this type of work yourself, mains electricity can injure or kill.
