How to choose your connected thermostat

The purchase of a connected thermostat is a real financial investment. And even if you have to invest a lot of money in such equipment, you might as well choose it intelligently.

#1 - Compatibility

Most of the current connected thermostats are compatible with Android and iOS operating systems. It is also possible to pair it with a connected speaker integrating a voice assistant likeAmazon Alexa, Google Assistant, Siri or even IFTTT.

#2 - The heating system

It should be noted that not all connected thermostats are necessarily compatible with the various existing heating systems. In general, an electric heater already has its built-in thermostat. Check that the model of your choice is suitable for your type of heating(electric radiator, boiler or heat pump).

#3 - The type of programming

Thanks to this criterion, you will be able to program the right temperature for your home. Some models offer the possibility of setting up a weekly program that you can control remotely through an app.

#4 - The integrated options

Today's

new generation of connected thermostat allows you to take advantage of many options already built in, including

:

  • Learning your daily habits
  • Monitoring of your energy consumption and calculation of your real expenses
  • Weather forecasting
  • Geolocation thanks to a presence detector

#5 - The effectiveness of the application

In addition to choosing the connected thermostat itself, also consider the app that comes with it or is compatible with it. Make sure it is intuitive and easy to use. Don't hesitate to do various tests (available for free on the manufacturer's website) to make sure.

What you need to know about how a connected thermostat works

The connected thermostat is no different from other models. It is easy to install on a radiator, air conditioner, boiler or heat pump. Its biggest feature is that it is connected. Therefore, it is equipped with a terminal ensuring a link to one or more connected devices such as a smartphone.

In addition to connecting to the Internet via WiFi or an Ethernet cable, you will also need proprietary software or a mobile application to use it. The difficulty of installing such equipment can vary depending on the model chosen. Simple for some, it is usually enough to disconnect the old model of thermostat in order to connect the new device.

On the other hand, connected thermostat models with a control center require a more complex installation. In this circumstance, you should seek the services of a professional to install the device on your heating system.

The different types of connected thermostats

As a rule, connected thermostats work in the same way since they use the same operating systems. However, it is possible to differentiate them more easily thanks to their mode of connection to the Internet. Therefore, we distinguish between wired and wireless models.

Connected wired thermostat

The connection of the connected thermostat is done via an RJ45 cable

. Its main role is to connect the smart device to the Internet box. You must have a cable of an appropriate length in proportion to the distance between the two devices. Also, you will definitely need to install other additional devices for concealing the cable.

The thermostat remains very secure while the flow rate is relatively high. If you're a bit of a do-it-yourselfer and installing RJ45 cables is not a problem for you, this model offered at a very good price will certainly suit you.

Wireless connected thermostat

The device is connected directly to the network through Wi-Fi. Since it doesn't require any special installation, you can place your wireless connected thermostat wherever you want. All you need is for the device as well as your smartphone, tablet or PC to be connected to your Internet network. Unlike a wired thermostat, there is no risk of network disruption, especially if you have children or pets.

The wireless connected thermostat is without a doubt the most interesting solution for better remote programming. This is the model you need if you want more freedom during installation and use.

The Bluetooth connected thermostat

Connecting via Bluetooth is a great solution as you won't need Wi-Fi to operate your connected thermostat. However, remote control could be a real drawback since the range of this technology is less.

Connected thermostat or heating programmer?

Connected thermostat

Just like a traditional thermostat, the main role of the connected thermostat is to manage the heating systems of a home. It generally acts on the boiler, the heat pump or the radiator depending on the model chosen. Connected, the device can be controlled remotely using a smartphone, tablet or PC. Wherever you are, your energy consumption can be monitored in real time. Similarly, the device offers to measure your habits and adapt to them in order to create a personalized program.

Heating programmer

The heating programmer differs a little from the connected thermostat since its role is to set up a temperature program according to defined schedules. It acts mainly on boilers and electric radiators. The comfort is optimal and the heating management will be done automatically once the program is established. Thus, thanks to the programmer, you will be able to heat your home only when it is necessary.

Verdict

In short, the connected thermostat allows you to choose the temperature in proportion to your needs. The heating programmer, on the other hand, is used to set a temperature according to specific schedules. This is a function that the thermostat does not have. However, coupled, these 2 devices are very effective. They will offer you the possibility to make real energy savings and to heat your home when you want.

Tips

Estimate the return on investment correctly

According to the manufacturers, the return on investment is estimated at about 12 months. You will benefit from an energy gain of about 20 to 40% depending on the model. However, it depends on your energy consumption, the number of people in your household, the size of your home and your insulation system.

Opt for a multi-zone connected thermostat

A

very interesting feature, the multi-zone offers you the possibility to manage more efficiently the temperature in your whole house. Controlling the right temperature for each room is done through the app.

Be careful with the installation of your connected thermostat

First, it's important to verify that the connected thermostat is compatible with your current heating unit. Turn off all power before installation. Insert the batteries and then connect the wires (following the color codes) between the two devices. After connecting it to an Internet network (via RJ45 cable or Wifi), use the mobile application to make all the appropriate settings. All the steps to follow are indicated there. Generally, it is necessary to wait up to 24 hours to receive the first information.

Remember the main features of a connected thermostat

A

connected thermostat offers several features that vary according to the model. Among others, you will appreciate the vacation program, the option to turn on and off the heating, humidity sensors, the "absence" function, self-programming and Autoadapt, weather prediction, open window detection, presence sensor... and many others.

Be careful with the budget

If

you need the help of a professional, be aware that the price of installing a connected thermostat ranges from €139 to €169. This rate can vary depending on the type of heating you have.
