Keep your home cosy (and save yourself some pennies too) with this Hive smart thermostat. Yep, even thermostats are smart now, meaning you’ll be able to control your heating using your phone – no more fiddling with old dials and vague buttons. Or you could use voice commands if you prefer, since it works with Alexa, Google Assistant and Siri, which is perfect if you’ve just cuddled up on the sofa and want it a bit warmer. And the best bit? You can set it all up yourself.
