The Nest thermostat is the market leading and probably best known of the smart heating controls. British Gas have developed their own version called “Hive” which is similar if a little less stylish.
The idea is simple, instead of having a timer you use the Nest to set the temperature of your home to the desired level. IF your not at home you can turn down the heating which both saves fuel and money. This can be remotely controlled from most leading smartphones like iPhone, Android and Windows Phone.
When Google purchased Nest there two products, the Nest and a lesser known Nest Fire Alarm. This is a smart device acts in exactly the same way as a normal fire alarm bit has several added features not least it can alert you via your mobile if smoke is detected in your home.
