This is more or less exactly what I need to run the solar heater on my garage. I’m currently using an Arduino and I’m working on an Rpi solution. I need to compare 2 Temps and control a fan depending on temps

@Niclas_Oberg Thanks for comment. ESP8266 is a cheap platform to do something like this. And the added advantage is WIFI, it gives you a lot of possibilities. In my house I intend to use the ESP8266 and Raspberry PI to control different devices using the MQTT protocol.
