This project is on hold for now as I would really like to make my all singing, all dancing smart switches that measure light and temperature, control music, heating and lighting. Even with this in mind I am still looking for simple components to make this and trying my hardest not to start adding lots of sensors to this.

There are a few components I am looking at including small Wi-Fi circuits as well as Arduino based solutions. Once I decide which way I am going with this so that I can get the best battery life I will post another update.
