Which? verdict: A brilliant smart thermostat

It might be one of the older models on the market, and it’s one of the more expensive smart thermostats you can buy, but this is still one of the best we’ve tested. The scheduling can be difficult, but its impressive learning capabilities means you might not need to manually program anyway.

Pros
  • Attractive and easy-to-use thermostat
  • Easy to install in the home
  • Lots of useful features including learning your routine
Cons
  • No significant cons – but the sheer number of features in the app can be confusing

Despite being a few years old now, this is still one of the very best smart thermostats you can buy. Not only is it a good-looking device, it’s also easy to install, set up and use, and the thermostat is accurate and responsive. A worthy Best Buy.

Pros
  • Thermostat accurate and responsive
  • App is easy to set up and use
  • Has a good range of features
  • Easy to install if you follow the instructions
Cons
  • Doesn’t support multi-zone heating

Which? verdict: A good all-round smart thermostat

It might have been around since 2015, but this is still a very good smart thermostat that we’re happy to recommend. The app can be confusing, but it’s easy to control the device manually or through the web portal. It also reads temperature accurately and is easy to install.

Pros
  • Simple controls on device
  • Thermostat is accurate
  • Easy to install and set up
  • Good web browser
Cons
  • App can be confusing
  • Fewer features than other top smart thermostats

Which? verdict: An impressive learning thermostat

It might be an older model, but this is still an intelligent and well-designed smart thermostat that does well across the board. It could be easier to use the manual controls, but the quality of the app more than makes up for this. It is still a Best Buy recommendation from us, and well worth considering for your smart home.

Pros
  • A well-designed and user-friendly app
  • Easy to self-install
  • Can add more devices
  • Fairly accurate
Cons
  • Awkward interface on the device
  • No weather response or GPS tracking

Which? verdict: Easy to use and set up

This is a very good smart thermostat with a bevy of useful features. It’s also easy to set up and use on a day-to-day basis. It just misses out on a Best Buy because the thermostat isn’t quite as responsive and accurate as some others we’ve tested.

Pros
  • Easy to use and install
  • Has a lot of useful features including zonal heating capabilities
Cons
  • The thermostat isn’t as accurate as the very best

Which? verdict: An accurate thermostat

This is a good smart thermostat that’s very responsive to temperature changes and reaches the desired temperature accurately. The app is also easy to set up and use. The device itself isn’t the easiest to set up, and it’s recommended this is done by a professional, which won’t be for everyone.

Pros
  • Good list of features
  • Intuitive app that’s easy to set up
  • Very accurate thermostat
  • Very responsive to temperature changes
Cons
  • Needs to be installed by a professional
  • Doesn’t have a motion sensor.

Which? verdict: A middle-of-the-road smart thermostat

The app works really well, but on balance we’re not overly impressed with this smart thermostat. Its score is only slightly higher than the Honeywell Lyric T6, as it also has the same problems. It doesn’t have quite as many features as others and is difficult to install.

Pros
  • Very accurate
  • App works very well on iOS
Cons
  • Not many features
  • Complicated setup

Which? verdict: Not the best

First released in 2016, it’s certainly not a bad smart thermostat, and the app works well. However, the installation is complicated and it’s not as easy to use or as feature-packed as one of our Best Buys.

Pros
  • Great app
  • Accurate temperature readings
Cons
  • Impractical installation
  • Hard to use device
  • Missing some features

Which? verdict: Still a decent smart thermostat

Despite being around for a while, this is a very good smart thermostat that has high-end features, is easy to control and is very accurate. It only misses out on a Best Buy because the functionality of the display is very limited compared with the best on the market.

Pros
  • Has a responsive and accurate thermostat
  • App is easy to use
  • Device is well designed making it easy to use and programme
Cons
  • You can’t schedule daily or weekly programmes on the device itself

Which? verdict: Uninspiring

This thermostat was first launched in 2013, and you can tell. If you’re looking for a really modern, well-designed smart thermostat, you might feel let down by this one. The app does work well, but it’s not as slick as some others, and it’s also missing some standard features that others offer.

Pros
  • Accurate temperature readings
  • Easy for a professional to install
  • Simple to use the app
Cons
  • Outdated design
  • Poor web portal
  • Limited features

Which? verdict: There are better smart thermostats

Overall, this is an average smart thermostat with a useful, well-designed app. However, it’s starting to show its age: it doesn’t have some of the basic features you’ll see on some other models, and it’s a pain to use the on-device controls.

Pros
  • Straightforward to install yourself
  • The app is intuitive to use
Cons
  • Not as easy to operate through the web or the device
  • Missing some key features
