Guide to Smart Thermostats

Thermostats are devices used to maintain the temperature in a certain place. They are usually mounted on the wall as control panels that let you adjust your heating and air conditioning system. There are also programmable thermostats which let you set the temperature and have the thermostat change it based on the time of the day. Amazing right? But that’s not yet the best kind of thermostat you can find in the market today.

With the advancement of technology, smart homes are becoming a trend with the use of smart home devices. Aside from the regular thermostats and the programmable ones, there are now smart thermostats that will enable you to control your home’s heating and cooling more conveniently from your phone, tablet, and other devices. If you’re interested to know more, here are the important things you should learn about smart thermostats.

What are Smart Thermostats and How Do They Work?

A smart thermostat is a new development which allows you to control your home’s temperature from your phone, tablet, and other devices. They are referred to as “smart” because they learn from your behaviors, allow you to control the temperature in your home remotely, adjust themselves based on ambient conditions like humidity, and show you energy consumption in real-time.

Smart thermostats commonly use three basic components. The first one plugs into your boiler and wirelessly communicate to the second component which is an in-home device that functions as the thermostat and main control. Its third component is an application that can be downloaded to your smartphone or tablet. Through the app, the user will be able to control the system remotely, allowing them to adjust the heating level from any location.

There are also other smart thermostats that offer more features such as learning your schedule and detecting you when you’re on your way home.

Functions of Smart Thermostats

The main responsibility of smart thermostats is to maintain the temperature in your home just like what other regular thermostats do. But since they are smart devices, they are able to give you more than that. Here are some other functions that smart thermostats can offer.

Hot Water Control

Aside from controlling your home’s heater and air conditioner, there are also smart thermostats that you can use to control hot water through your phone or tablet. It is great for those who do not have double boilers which provide hot water instantly. However, not all models have this function and some might charge you extra for it.

Through the use of a smart thermostat app, you will be able to turn on the hot water in your home more conveniently even when you’re away. For example, if you’ve switched off the hot water at home because you were away for a few days, but you’d like a nice hot bath when you get back, you can simply turn it back on using your smart phone before you get home. With this function, you will never have to suffer a cold shower again because you forgot to put the hot water on.


Smart thermostats have the ability to learn your routine and your preferred temperatures. In fact, they can program themselves according to your preferences. This function will help you save time from having to program a schedule yourself. But if you do not like the schedule it has programmed, you can also turn this feature off and switch back to manual control to program it yourself.

Multi-Room Control

Through the use of an app, some smart thermostats will allow you to set different temperatures in different parts of your home. This function is very useful especially for those who have larger homes.

For example, if you usually stay in your entertainment room in the evening to watch a movie, you can keep it nice and cozy while turning the heating down or off in the other rooms that are not in use. However, to be able to use this feature, you’ll need to buy extra thermostats for each area that you want to use different settings for.

Motion Sensors and GPS Tracking

There are smart thermostats that use motion sensors to detect whenever you leave and enter your home, and GPS tracking to set boundary lines around your home. This way, they will be able to adjust the heat settings accordingly. When you leave, they are able to turn the heating down, then pre-heating it again when they detect that you’re on your way back or near the boundary lines. This way, your home will have the right temperature once you get back.

There are also some smart thermostats that can alert you on your smartphone when you’ve left the heating on or when the temperature is set lower than you’d like when you’re coming back. However, they only inform you but won’t adjust the settings automatically.

The motion sensor and GPS tracking feature are best for people who are in and out of the house at irregular times.


Smart thermostats feature a weather-responsive function where they adjust the internal temperature automatically according to the weather forecast and temperature outside. If it’s cold outside or if it going to be sunny, the smart thermostat will adjust its temperature settings to reflect that the temperature will change.

Benefits of Smart Thermostats

Smart thermostats are best for people who have busy schedules. For example, if you left your thermostat on when you leave the house, it will be able to detect that no one is home, and will automatically turn off for you.

Smart thermostat

They can also help you save money, not in a direct way, but they will allow you to heat your home more efficiently, thus, helping you save money in the long run. Smart thermostats can also give you reports about your usage. You can use this information to understand your heating patterns. This way, you will be able to change your behavior to be more efficient and save money.

The best thing about smart thermostats is they are designed to make your life easier and to do the thinking for you. It provides you with both comfort and convenience.

Things to Consider in Smart Thermostats

If you plan on purchasing a smart thermostat, there are some factors to consider first such as your heating and cooling system, your internet connectivity, and the product’s feature. Before deciding on one smart thermostat to buy, here are some of the things you should look into for you to choose the best one and enjoy its functionality.

Device Specifics

To know the best smart thermostat for you, the first thing you need to do is to find out the HVAC system you have. After that, decide whether you’d like a wireless thermostat or a hard-wired one. Whichever you choose, both are still needed to be connected to Wi-Fi to work and to be compatible with other devices.


Smart thermostats with hardwiring do not require any batteries and they are low-maintenance. However, your system’s wiring can affect your purchase because heating and cooling systems have slightly different wirings from one another.


Wireless smart thermostats, on the other hand, are powered using batteries. It is convenient in places that frequently loses power. However, this also means that you will have to check for corroded batteries and replace them on a regular basis.

Heating and Cooling Systems

The type of smart thermostat you should buy depends on the heating, ventilation, and air conditioning (HVAC) you have. It’s because there are some smart thermostats that are not compatible with solid fuel furnaces but can work with heat pumps. Therefore, you’ll have to know first if the smart thermostat you want is compatible with your HVAC system at home.


Having an internet connection at home is important if you want a smart thermostat. It’s because it is the system used for you to control the thermostat remotely from your phone and tablet. If you lose the network, you will have to adjust the thermostat manually.

Smart Home Systems

If you have a smart home hub like Google Home or Amazon Alexa, you can also link your smart thermostat to it if they are compatible.


These are important things to look into when purchasing a smart thermostat. When deciding on features, you should think first if that certain function it offers is essential. Here are some of the best features of smart thermostats you can consider.

  • Touchscreen: Having a touchscreen smart thermostat will give you more hands-on control. But you have to make sure to keep them out of reach from children because they might play with it.
  • Motion Sensitivity: This feature might help you save energy because when a smart thermostat has motion sensitivity, it will be able to detect if there is someone in the room and automatically adjusts to your preferred settings. There are some smart thermostats where this feature is included in the package.
  • Geo-Fencing: This is the feature that can track when you’re away from home. It sets the boundary line around your home, therefore, when you leave, the thermostat will be notified and it will turn the dial down to a low temperature.
  • Alerts: There are some smart thermostats that can alert you when your furnace filter needs to be changed or needs to be serviced. This might also be a useful feature.
  • Thermostat App: This is a very important feature especially if you want to control your home’s temperature remotely. It will allow you to auto-schedule your thermostat easily.
