[This is] my solution of how I have saved some heating costs/energy use and to seed the thought into you, so it can be adopted into your home or modified to suite your needs.
In the Spring and Autumn months where the outside air temperature can be around 11degC I noticed my house lost little to no temperature to outside. I also noticed that in the morning the heating would come on for some time (upto 30minutes) then stay off until the next day. I saw this as a waste of energy as on a sunny day or as at warms above 12degC outside the house will naturally warm to a comfortable temperature. Normally this would be the time of year that I would turn my heating off to save Gas usage. This project is to automate this process based on local outside air temperature and utilising some of my existing household temperature sensors, the project has the advantage of knowing the temperature predicted and acting upon it but if the house lost too much temperature it will allow the heating to come back on.
