Factors to Consider

Now that you have seen a few reviews on different smart thermostats available to you, we will go one step further and help explain different factors that you should consider before making the final purchasing decision for your household.

Schedule Setting

The whole point of a smart thermostat is to help you save money on energy usage. To do that, you need a thermostat that you know will adjust your heating and cooling usage based on times when you are and are not home.

There are programmable thermostats that are not smart thermostats, but the smart thermostat is designed to learn your schedule naturally.


Not all smart thermostats come compatible with its app, which means you have to rely on the device doing what you set it to do while you are away from home.

It is recommended to look for a smart thermostat that has an easy-to-use app so that you can monitor your energy usage even while you are away from home, and sometimes, these apps even allow you to adjust your settings from the app.


Some thermostats come with room sensors included with the thermostat, and others require you to purchase the sensors separately.

These sensors will trigger the thermostat to kick on through motion in the room where they are placed.

Compatibility with other Smart Home Systems

Many people use Amazon Alexa or Google Assist. Many smart thermostats can sync with these home systems which gives them other functions like voice control when paired with these systems.

Finally, you might want to purchase a smart thermostat that will allow you to monitor your energy usage over time. This is one of the best ways to ensure that you are saving as much money as possible with your new smart thermostat.


Do smart thermostats help save money on energy?

Yes. Smart thermostats are capable of helping you save money on your energy bill, but they must be set up and configured correctly. Most smart thermostats provide you with usage reports for the month or week, and you must manage them to see where you can save even more money on your energy bill.

Will smart thermostats work without being connected to Wi-Fi?

This is entirely dependent on the smart thermostat that is chosen. If you need to have a thermostat that might lose connection to a Wi-Fi signal or you don’t have a Wi-Fi set up in your home, you need to make sure that the smart thermostat you are choosing will still operate, before purchasing it.

Why should you consider getting a multi-zone smart thermostat?

Smart thermostats are designed to learn a household’s schedule and pattern to assist them in keeping their energy usage down.

They are especially recommended for people who travel often or have regular schedules where their home is empty.

These thermostats will allow people to set schedules so their heating and cooling system kicks on at certain times when they are going to be home and turn them off when they are away to save on energy usage.
