OTGW-firmware

ESP32/ESP8266 firmware turning an OpenTherm Gateway into a networked smart heating controller.

PlatformWebfreeglobal

An ESP32/ESP8266 firmware that turns a NodoShop OpenTherm Gateway into a networked heating controller by monitoring the OpenTherm bus and exposing MQTT, a browser web interface, and a REST API. It provides a weather‑compensated PID autotune thermostat that can run the heating loop standalone and supports OLED, BLE room sensors, and Ethernet failover; intended for home automation hobbyists who own an OTGW/OTGW32 board and can flash an ESP module.
