How Do Smart Home Thermostats Work | Facts No One Tell You

It doesn’t matter whether it’s in the morning in the bathroom, in the evening watching a movie, or while you sleep, the right room temperature makes you feel good in any situation. The intelligent heating control through smart home thermostats optimizes your heating behavior. It allows for more comfort and energy efficiency with little effort—goodbye to tedious and permanent adjustment to each radiator. In this article, we will discuss about how do smart home thermostats work.

A thermostat comes as a device used to regulate the temperature in heating and cooling systems. Until a few years ago, the options in thermostats were mainly two:

Analog thermostat: It is the one for a lifetime. It has a small wheel to move to the desired temperature, and although it is straightforward to use, it has the disadvantage of not being very precise, and therefore not very efficient. They are becoming obsolete, more and more.

Digital thermostat: This has been supplanting the analog one for being more efficient. Instead of the temperature control wheel, it has a digital display and buttons, with which you can set the temperature precisely. Also, they allow temperature programming.

To these two is added the Wi-Fi thermostat, or also called a smart thermostat. It goes a step further technologically speaking, connecting to the home Wi-Fi network and controlling it through apps with the mobile, not only from home but also from outside. This opens a window of added possibilities, such as constant monitoring of consumption or adapting the temperature according to the weather forecast.

How do Smart Home Thermostats Work?

To understand how a smart home thermostat work, it would be necessary first to explain how traditional thermostats work. We will do it very briefly so that everyone understands.

An analog thermostat works connected by two wires that go to the boiler. This thermostat has a relay inside it, an electromagnetic device that works as a switch. When it is activated, it joins the two cables so that the boiler starts working, and when it stops, it turns it off. As you can see, it is a straightforward mechanism.

A smart home thermostat works precisely the same, though with more functions and possibilities, all of which allow an internet connection and have multiple sensors for temperature control. Also, the best thermostat Wi-Fi on the market has the particularity of separating the relay from the thermostat in question. A relay call bridge ( bridge ) or link and the usefulness of separating it from the thermostat is that you can take this to any corner of the house, not necessarily to the living room (which is where we usually install technical thermostat) or near the boiler.

Separating the relay from the thermostat and turning it into a bridge allows us to add more thermostats at home, for example, one for each room. As you can see, thanks to smart thermostats, home heating and cooling have become a new world with dozens of possibilities and advantages.

How do Smart Home Thermostats Work: Installation Procedure

Installing a Smart home thermostat is very simple. It is best to install the relay or bridge in the same place where the analog or digital thermostat used to be since that is where the two boiler cables go (they are circuit, one open and one closed). This type of installation is the best because it allows you to take the thermostat with Wi-Fi to the corner of the house that you prefer. You could even choose to make your thermostat mobile, relocating it as you see fit.

It must be said that this is the most common installation for the vast majority of boilers, but there are some with more cables or with additional steps that must be consulted very well before starting to do so. What we describe here is the typical installation:

  • The first thing is to turn off the boiler and cut the light. We are going to work with electrical elements, and we must always prevent possibilities of sparks or electric shocks.
  • Next, remove the old thermostat, and in doing so, you identify the cables, which should be 4: two for power and another two for the boiler circuit.
  • Take the relay, bridge, or link with which the thermostat comes, and connect the four cables as appropriate and indicated in the thermostat installation manual.
  • Hook the relay to the wall. Some models allow fixing without holes, while others will force you to do them.
  • Now, you can install the thermostat wherever you want. The thermostat needs power; Depending on the model, it will have to be powered with batteries or electric power cables.
  • Next, turn on the light and the boiler again.

Advantages of Having a Smart Home Thermostat

The advantages and benefits of smart home thermostats are many. These are the main ones:

Energy Saving 

Smart home thermostats’ energy-saving capability stands as primary merit and makes it more advisable to install one. According to studies, savings range from 40% to 20%; In any case, energy savings are significantly ensured by the precision with which they work and their adaptability to alter the home’s temperature.

Automatic Temperature Adjustment

The automatic adjustment of temperature is one of the strengths of a Wi-Fi thermostat. This can be achieved through temperature sensors and weather forecasting or data collected from weather stations over the internet.

Habit Learning

The habit of learning is perhaps the characteristic for which the tagline ‘smart’ is given to these thermostats.’ The Wi-Fi thermostats learn from your habits and temperature preferences to save energy and ensure your comfort. Thus, the thermostat knows, for example, what time you usually arrive home and with what temperature you feel comfortable at that time of year. Based on this and the current temperature or the weather forecast, you know whether to turn on the boiler more or less in advance so that the heating is ready when you get home.

Home Automation Integration 

Home automation integration is another exciting feature of the smart home thermostats. This is quite possible because most Wi-Fi thermostats can be integrated with home automation systems such as Alexa, Apple Homekit, or Google Assistant. In this way, you can make a motion sensor activate a thermostat function or give it commands by voice commands in Wi-Fi speakers that you have at home.

Remote Control 

The remote control is another feature of smart home thermostats that should not be underestimated. There are few times that you leave the house having forgotten to turn off the heating system. Thanks to a Wi-Fi thermostat and the app that controls it, you can turn it off or on whenever and wherever you want. You can also regulate the temperature without getting up from the sofa or a specific room being in another part of the house.

How do remote thermostats work?

Remote thermostats work through the aid of remote sensors. A remote sensor is a device designed to allow a thermostat to control a room’s temperature based on the room’s occupancy rate and temperature level. These remote sensors are used in conjunction with thermostats and heating units to ensure that only rooms that need to be heated are warmed up. This not only makes your home comfortable and energy-efficient but also saves you money. Remote sensors are placed in different rooms; regardless of whether the room is occupied, they will send information about the temperature levels back to the thermostat. Therefore, the wireless thermostat will adjust it is heating or cooling method to make the hot room cooler and the cold room hotter. This would thereby keep the entire house comfortable.

Final Words

In conclusion, a smart home thermostat heats your home or apartment only when you need it. Today, you can program fixed intervals and manage radiators spontaneously, thanks to the application. Smart heating can also be coupled with other smart home devices such as door or window sensors. Above all, purchasing intelligent heating control pays off greatly. By optimizing heating, you save energy, reduce costs, and help preserve the environment.
