Top 10 Best Smart Thermostats [2024]

If you’re looking to save money on energy bills for your home, a smart thermostat is one of the best ways of doing that. With a smart thermostat, you will have full control over the temperature in your home and will be able to create smart schedules for optimal energy usage.

What To Look For in a Smart Thermostat


Installing a smart thermostat should be simple to do, even if you’re unfamiliar with the procedure. You should be able to find easy-to-follow instructions with the packaging, or there should be a copy available online.

Instructions provided should have clear illustrations that can help guide you through the installation process. Any wires or cables should be marked in a way that shows you exactly where each one must go. For example, the wires included could be color-coded or labeled.

It should take around half an hour to replace your current thermostat with a new smart thermostat. If you get a bit stuck, most manufacturers have customer service reps that can help talk you through the instructions.

After installation is complete, you should download the smart thermostat app onto your smartphone or another device so that you can use it to its full potential.

Smart Home System Integration

With every smart thermostat, an app can be downloaded so that you can control it with ease from afar, but some models can be integrated with other smart-home systems such as your voice assistant and other devices.

If you link the smart thermostat with your Amazon Alexa or Google Home, you will be able to control it and adjust the temperature by using voice commands. This can be great for extra convenience in your life.

It’s possible to link your smart thermostat to your smoke detector. This way, when smoke or a fire is detected, the smart thermostat can switch off any fans to prevent any smoke from being spread around your home.

Other options that can be linked with your smart thermostat include smart-vent connectivity for further temperature control and links with any home security system.

Remote Access

Remote access with a smart thermostat can allow you to control the thermostat remotely from anywhere. To be able to do this, all you need is the available app and a Wi-Fi connection.

You can adjust the temperature with remote access whilst you’re away before you get home for maximum comfort. You can set schedules for your temperature changes, but sometimes we need something that is cooler or warmer than normal.


Geofencing is a feature that can use the smart thermostat app and the GPS chip in your smartphone to set a perimeter (or a geofence) around your home. Whilst you’re within the perimeter, the smart thermostat will continue to heat or cool your home, but once you leave the perimeter, it will stop so that you can save your energy and avoid wasting it.

If you leave the perimeter and then come back later, the HVAC system will power up so that your home will be temperature ready for when you get back. You’ll no longer need to wait for your home to warm up or cool down.

Room Sensors

You can have models of smart thermostats that come with portable room sensors for any hot or cold spots within your home. These sensors are designed to be placed in areas where the temperatures are often different from the center of your home.

Room sensors can assist in making sure every room is heated or cooled to the right temperature throughout the day.

C-wire Requirement

Many smart thermostat models aren’t battery-powered and will need to be wired into your home. There’s no need to worry about them be expensive to run as they are designed to not take up too much power. As a smart thermostat will actually help you save money on energy bills, you won’t notice any extra costs from having one installed.

Many smart thermostats need to have a dedicated C-wire (common wire) to be wired into your home. A C-wire allows for a constant flow of power to a smart thermostat. It doesn’t act as the source of power, but it helps to complete the R-wire (power wire) circuit to the HVAC system so that the display and the Wi-Fi connection can run 24/7.

If you pull out your current thermostat and find that there’s no C-wire connected to it, you should look inside the wall to see if there’s one hiding away. If not, it’s a good idea to get one installed. Not all smart thermostats models need to have a C-wire, but it’s highly recommended to get one to avoid any damage or other problems with the HVAC system.


Smart thermostat alerts can notify you of any temperature changes that happen in your home whilst you’re away. This can help you to keep your home safe from any extreme changes that can lead to further damage.

With the smart thermostat companion app, you can remotely adjust the temperature to fix any problems, or you can ask someone you trust to go to your home and see if there are any issues.

Color Touch Screen and Proximity Sensor

A lot of smart thermostat models come with a large touch screen display for easy temperature management. You can see important information such as your home’s current temperature, the date and time, and sometimes even the weather outside.

The information shown on display should not be too sophisticated and must be able to give you the needed information at a quick glance. Some models allow you to decide what information you would like to see, so if you don’t need the date and time, you can choose not to have it there.

These touch screen displays will often brighten up when your walk close by within its range and then dim again once you walk away. This is known and a proximity sensor, and it can be useful for saving more energy and helping the display to last for a longer time.
