A connected thermostat, what is it?
Nest, Netatmo, Qivivo … We have all heard these names at least once and we can say that they are connected thermostats. On the other hand, if we are asked what exactly is a connected thermostat, the answer is much less obvious to formulate. At random, we explain that it is a plastic case that is fixed to a place in his house or apartment and that allows to adjust the temperature of the room. It's a good start, but it's a bit more complicated than that.
Since the invention of the thermostat in 1886 by a certain Albert Butz, this system of temperature regulation has largely democratized and technological advances require, the latter has become connected (in WiFi, with the Internet box). Today's thermostats are therefore controlled by a smartphone, a tablet or directly from a PC, and can be controlled remotely, to better manage its energy consumption.
And what is it for?
Well, to reduce its consumption and consequently, its expenses. Depending on the product, there are more or less advanced features, depending mostly on the functionality of the thermostat, or what you expect. Whether the thermostat is connected or not, there is one essential function: programming. This will allow you to schedule departures on weekends or holidays, but also to manage the temperature according to your working days for example, and thus avoid heating the habitat for furniture. And the simpler the programming mode, the more attractive the product becomes.
For connected products of this type, functions such as weather forecasts, consumption statistics, calculation of thermal inertia (speed of cooling or heating of a fireplace for optimal adjustment), or integration of a guest mode (to allow connections from several people from the home in particular) are things that are found on most thermostats, regardless of their price range.
But there is a huge number of features. Some thermostats embed sensors to reduce heating automatically when no one is detected in the habitat, have geolocation modes to define an activation perimeter (eg when you are more than 2 km away from home), or provide home insulation analysis, thermal impact of local weather, or brightness level. In short, a host of possibilities that vary by model.
Is it difficult to install?
If you ask a seller or a manufacturer if the product is difficult to install, you should 99% of the time harvest a "no". Because obviously, saying that his equipment is not within the reach of the first handyman on Sunday that passes, it does not sell. But in reality, installing a connected thermostat is not easy. Fortunately, manufacturers generally offer explanatory videos, installation manuals and, in the worst case, installation packages with the purchase of the product.
Real savings at the end of the month?
In short, there are many references more or less known in the market, but all have the same goal: to offer a reduction of electricity bills to customers. It should be known that heating accounts for more than 60% of household energy bills, and that connected thermostats allow, according to the French Environment and Energy Management Agency (ADEME), to reduce this energy bill. 5 to 15% depending on the effectiveness of the programming performed. What to make quickly the purchase of a product of this type.
