How did we choose?
If you are riding the wave of the smart home, you are probably seduced by the idea of being able to connect your heating. Thus, your interior will benefit from an ideal temperature at all times, and the smart thermostat will also allow you to make great energy savings!
According to Marie Jehanne, a specialist in connected thermostats at Hello Watt , the savings made thanks to this type of thermostat would be 20% on average. It is therefore ideal for your comfort as for your wallet. But you still have to find the model that suits your desires.
Here are a few things you should know before you buy, which should help you make your choice:
- Connection : thermostats use Wi-Fi to connect to your smartphone or tablet, so you can control your heating remotely (at the office or even abroad, for example). Some models require a bridge or gateway, which acts as an intermediary between the modules and the Internet. They may have an additional cost, as they are not always included in the purchase.
- Compatibility : today’s thermostats are often compatible with a wide range of heating systems . Before any purchase, be sure to check if the product you want to buy goes hand in hand with your heating system: this will save you unnecessary hassle. Many are also compatible with various voice assistants such as Amazon Alexa, Google Assistant or the IFTTT application (which optimizes the interconnection and functionality of your devices).
- Ease of use : first of all, the application created by the brand to manage the thermostat must be intuitive and clear, without which you will not be able to fully benefit from the advantages linked to connected devices. In addition, a simple installation that can be done alone is practical, since the need for an electrician obviously increases the bill. But, if in doubt, it’s still a safe option.
- Additional features : many features are available on most models, and are likely to simplify your life: geolocation makes it possible, for example, to detect your proximity to the house, and to adapt the resumption or interruption of the heating accordingly, while the weather mode adjusts the indoor temperature and heating time in relation to the outdoor weather conditions.
It is with these criteria in mind that we conducted our research on various sites specialized in heating and / or home automation. We also compared the 15 or so pre-selected models with consumers’ opinions and their experience with the brand’s After-Sales Service (since installing this kind of product often requires a little help).
Following these in-depth analyzes, we have deduced that the following 3 models present the best quality / price ratio on the market.

It is not easy to find connected thermostats offered at a really low price. Models under 100 € are often either sold without the accessories necessary for their proper functioning (which will raise the purchase price significantly), or orders more than thermostats themselves.
However, we managed to find a model with its installation kit at an attractive price and which is obviously not without efficiency and practicality of use.
