Electric heater controller

Project description

The thermal insulation of my apartment not being the best, I had to buy an electric heater in order not to freeze during cold winter nights. However, the one I got was probably too powerful for my needs and letting it run for too long would heat up my place too much. Thus, I added a wifi enabled controller to it so its operations are controlled by my home automation system.

The heater itself is pretty silent. However, the click of an electromechanical relay might get annoying during the night so I chose to use a solid state relay to turn the heater on and off.

The electronics are installed in a 3D printed enclosure attached to the back of the heater.
