In my quest to try and automate my home as much as possible I'm now looking at a smart thermostat.
I've narrowed it down to the Nest or Tado. The nest has a sexy look (design by the same lot as the ipod) whereas the Tado has the location awareness feature. I have seen people using IFFFT to control the nest location awareness so that may not be an issue.

Does anyone have any experience with either? A big question would be will it work with my heating? I assume I would leave my heating on the "all day" setting and let either thermostat work it out?

My heating system has a boiler in the kitchen, a wired thermostat on the wall, a programmer in a cupboard in the bathroom and a hot water cylinder.
