When energy prices soared the drive to design and implement a better way of tracking and controlling the heating of my home got serious. Several project ideas emerged to accomplish this with the ESP32 micro controller. First idea was to take control of the hydronic floor heating. Second was to replace the mixing valve controller for the radiator and floor heating circuits. Third was to get good outdoor temperature measurements. Forth was to get good room climate measurements. All of these ideas are under development and testing in real operating conditions.

The code and development description is made available in GitHub.
