10 Best Wifi Thermostats

The Hive Thermostat with the Nano 3 Hub is designed specifically for homes with combi boilers, using OpenTherm technology to improve heating efficiency by adjusting boiler output precisely. This means it can lower gas use by up to 12%, potentially saving money and extending your boiler’s life. The thermostat connects via Wi-Fi through the new Nano 3 Hub, which is compact and handles multiple devices smoothly, making it reliable for larger smart home setups. The user interface is graphical and controlled by push buttons, offering straightforward operation without complex menus.

You can program heating and hot water schedules with up to six daily time slots, which is flexible enough for most daily routines, plus features like boost mode and frost protection add extra convenience and safety. Geolocation helps adjust heating based on when you leave or return home, and holiday mode lets you pause heating while away, so you don’t waste energy. However, this thermostat only works with combi boilers, so it’s not suitable if you have other types of heating systems. Also, it requires a power cable rather than being battery operated, which may limit installation options.

While it integrates well within the Hive ecosystem, it may not be compatible with all smart home platforms if you use others beyond Hive. For UK users looking for an energy-efficient, easy-to-use thermostat compatible with combi boilers and connected via Wi-Fi, this offers good value and solid features. If your heating setup differs or you want broader smart home compatibility, you might want to explore other options.

This thermostat only works with conventional boilers, so it won't be compatible with combi or system boilers. While it offers remote access and basic energy-saving features, it doesn’t have detailed energy monitoring compared to some other smart thermostats.

It supports 7-day scheduling with multiple temperature setpoints, allowing you to tailor heating to your weekly routine and potentially save on energy bills. The thermostat also features geofencing and adaptive scheduling, meaning it can learn your habits and adjust accordingly — a plus for comfort and efficiency. Installation is fairly simple, and it works with a variety of heating systems, including gas boilers, heat pumps, and zone valves.
