aipool

AIPool - automated pool filter backwashing on ESP32CAM. The goal: read the filter's pressure gauge with a camera, run the pool pump and a 3-relay valve actuator over a shared RS485 bus, and orchestrate the full FILTER-BACKWASH cycle with QR-code WiFi provisioning and a polling HTTP API. The stack is a single ESP32CAM app backed by portable C libraries, gauge reader, Modbus relay and pump drivers, quirc-based QR decoder each proven by its own hardware-in-the-loop test rig, plus a Home Assistant package (live sensors, staleness guards, backwash controls, scheduled runs, Home Assistang Lovelace dashboard) verified against the live device. Hardware is bench-built: ESP32CAM + RS485 transceiver + 8-ch relay board + valve actuator and pump motor on 5/12 VDC and 24 VAC supplies, all validated end-to-end from QR scan to running the pump and controlling the valve.
