Home Automation of Rinnai Gas Heater
Our Rinnai heater is a wall mounted/flued gas fire. Current control is via a large LCD remote control that also acts as the temperature sensor, and thermostat. It has some auto timing capability via way of programming the remote, but it is a bit clunky and not intuitive. The goal was to enable a better PID control of the temperature, and switch off/on control (occupancy, remotely before arrival, voice control, better scheduling etc). This shows how I connected to it with Home Assistant.
