Nest 3.0 Stuff says ★★★★★ Our favourite thermostat cranks up the heat up on its smart home rivals

£279 with installation / nest.com

The Nest 3.0 is not a dramatic reinvention, but it didn’t need to be: this is still the best-looking and most rewarding smart thermostat on the market. Nest learns your habits – when you’re in the house, when you’re likely to need a lot of hot water and so on – so it can control the boiler to save energy and keep that shower nice and toasty. That, paired with a nicely designed app, is enough to put it ahead of the competition.
