I live in a rented house and my current heating system isn't great. The timer on the boiler is only a 24h clock and I have a feeling the thermostat temperature is wrong. This combination means that I often wake up on the weekend to a cold house.
A friend has a similar system, but the timer is broken. He told me how he controls it with a servo and an Arduino. I'm setting out to do a similar setup, but I'd also like to hook it into my home automation bot, as well as making it a bit smarter.
