I needed to make a controller for my cheap and simple heater. It don't have any termostat and the setting are really strange and I could not find the correct settings, either too hot or too cold. I connected a 433 sender to a raspberry pi and made a flask web API. I then added a switch in Home Assistant that run a curl command to the other pi.
