This setup allows Arduino to read temperature, control relay based on setpoints, display info on OLED screen, and manage date/time settings with user input through buttons. Adjust based on specific hardware/project requirements.

Designed to replace the faulty electronic control of a blue heat radiator.

    That’s pretty cool, I was thinking about building my own thermostat a few years ago.

    My previous one died and the company stopped making them. But what I really liked is that it was a “smart” thermostat that was made before the IoT age.

    It was “smart” in a way that it had a motion sensor and basically just turned on the heating for 1 to 3 hours after it saw motion. The duration was something you could set yourself.

    I really liked that concept, because I never had to change anything during a holiday or even a night in a hotel. If you aren’t at home, no motion, no unnecessary heating.

    The thermostat was in a pretty central place in our house so you would definitely trigger it every 2 hours when getting a drink or using the toilet.
