Ecobee 4 Smart Thermostat Review

Being able to control the temperature in your home is a blessing, and so a thermostat can be a great device at home. Having an HVAC system at home means you need to invest in a thermostat as well. However, now that thermostats have shifted from the manual ones to automatic and smart ones, picking one is not that easy.

Thermostats nowadays come in a variety of features such as programmability, Wi-Fi connectivity, and compatibility with other smart devices. Not all thermostats will have the same functions and thus, they all are unique and come in different price ranges. Let’s look at some of the benefits of having smart thermostats installed in homes.

Smart Thermostats

Smart thermostats are great for someone who is looking to save up on annual energy costs. While the initial investment may be hefty, it is still worthwhile in the long run. Many smart thermostats are also energy-star certified which guarantees that they will help save your electricity costs. They have simple touchscreens that make navigation a breeze and programming easier.

Additionally, the feature that sets smart thermostats apart from the simple programmable ones is their ability to connect to the internet. By connecting the thermostat to the Wi-Fi, you can control the thermostat from your smartphone, PC, or tablet, by simply downloading the smartphone app. Additionally, smart thermostats offer compatibility with a variety of smart home systems so that you can control the temperature without even using your phone.

Essentially, you just have to make sure the thermostat is compatible with your smart home system to be able to give it voice commands. Some smart thermostats are smarter than others.

For instance, some also come with smart sensor technology, which can detect things like humidity, proximity, and motion. Some smart thermostats, that are high end, are also equipped with advanced learning abilities, where the user’s involvement with the thermostat is even more minimalized.

Since smart thermostats vary so much, it is a good idea to find one that is perfect for your needs. I also made the mistake of buying one that was not compatible with my HVAC system and then I had to look for another one.

This is a review specifically for the Ecobee4 smart thermostat, and it will act as a buying guide for anyone interested in it. However, it also includes alternatives to the Ecobee4, in case it is not a good fit for your home.

Who should buy smart thermostats?

Smart thermostats are for anyone looking to automate their temperature control process. If you are tired of having to constantly adjust the thermostat at home, then you have come to the right place. Smart thermostats are for people who are especially looking t reduce their electricity costs at home.

Smart thermostats have functions that monitor and keep track of energy consumption. They are also equipped to make adjustments on their own that minimize energy consumption. Furthermore, if you want to be able to make a schedule instead of manually changing the temperature then a smart thermostat is a good option.

People who travel a lot should opt for smart thermostats as they are equipped to know when you are home and when you are not. Moreover, to make sure you don’t come to an extremely hot or freezing house, a smart thermostat will let you switch the HVAC system on through your smartphone. Thus, anyone looking for more convenience and comfort in their homes should buy a smart thermostat.

Factors to keep in mind before buying a Smart Thermostat:

1. Power

Your smart thermostat and HVAC system must have the same voltage requirement. While most have a 24 V requirement, some HVAC systems are multi-stage systems that have furnaces or ACs. These systems have more than one level of heating and so require thermostats that support more than one kind of heating too. Thus, before you buy a thermostat, make sure it supports the HVAC system you have at home.

2. Ease of Installation

While most smart thermostats can be installed at home with the help of the manual or YouTube tutorials, others require professional installation. If your thermostat comes with a c-wire and if you don’t have a c-wire connection already you will have to get one installed beforehand. Hence, if you do not want to get a new connection or professional help, then make sure you go for a smart thermostat that does not have these requirements.

3. Advanced features

smart thermostats not only offer smart home compatibility and Wi-Fi connectivity but are sometimes more complex than that. Some smart thermostats are built on algorithms that learn the user’s temperature patterns that are then used by the thermostat o create your schedules. This is mostly found in more expensive thermostats as they use advanced technology.

4. Geofencing

This feature let the thermostat know if your smartphone is within a given radius or not. If it detects the phone’s GPS signals, the smart thermostat knows that you are home and if it doesn’t, it automatically adjusts the temperature to conserve energy.

5. Monthly Reports and Reminders

Some thermostats also come with usage reports that help track energy consumption. They are quite useful for someone who wants to know the energy consumption patterns of their HVAC system. They also sometimes give reminders and alerts for when the filter needs changing or the thermostat reaches low or high temperatures.
