App watch: Nest Thermostat

Control the central heating from your phone

Simply install the unit and use your phone to set the temperature – no more annoying trips to the airing cupboard to tweak a degree or two. The Nest Thermostat is a new way to control your home heating. Best of all it works with your existing system, so you won’t need to rip out old boilers and pipes.

You don’t need to program Nest. Just use it for a week and it learns how warm you like your home and when you want the heating on. It even knows when you’ve left the building (using phone sensors) and turns itself off while you’re at work. Nifty.
