This thermostat is versatile in terms of how you control its functionalities. Using an app, you can control your room’s temperature through:

  • Tapping. You can either tap on the thermostat itself or the Ecobee app to control your room temperature. The tap sends a signal to the thermostat, which then adjusts the temperature in your room.
  • Swiping. You can swipe up or down on either the Ecobee app or the thermostat itself to adjust your room’s temperature.

Follow Me Plus Home and Away

According to the U.S. Energy Information Administration, the average electricity bill for households in the country in 2020 was $117.46 monthly. This high cost of electricity is partly contributed by HVAC systems that remain in operation even when people are not in the house.

The Follow Me Plus feature on this thermostat allows you to save on your heating and cooling costs based on your location.

This feature uses the sensors in your Ecobee lite to detect when someone is home. When it senses that all rooms are unoccupied, it’ll automatically adjust the temperature to save on energy.

You can also use the Home and Away feature to schedule when you’re home or away. This feature will adjust the temperature based on your schedule, so you don’t have to worry about manually adjusting it.

Ecobee Smart Thermostat

The Ecobee Smart thermostat is the latest model from Ecobee. It has all the features of the lite version, plus some advanced features that make it worth the extra money.

Like the Ecobee Lite 3, the smart thermostat makes controlling your room needs like temperature and heating easier through voice control and tapping. In addition, the smart version has an advanced Amazon Alexa speaker that lets you play music, respond to texts, and send messages.

Other functionalities of the Ecobee Smart thermostat are:

Energy-Saving Features

The smart thermostat uses geofencing technology to save you money on your energy bills. This feature uses your phone’s location to detect when you’re away from home. When it senses that you’re away, it’ll automatically adjust the temperature to save on energy.

You can also set a schedule for when eco mode should be activated to allow the smart recovery feature to heat or cool your home at the right time, so you’re comfortable when you come home.

Advanced Amazon Alexa Speaker

The smart thermostat comes with an advanced Amazon Alexa speaker that enables you to play music, respond to calls and send text messages automatically.

You can also use the speaker to control smart home devices like lights and door locks.

The speaker makes your life easier by eliminating the need to adjust your smart home devices manually. Therefore, it’s an excellent option if you always come home tired and want to control your devices remotely.

The Power Extender Kit

Most HVAC installations come with a blue C wire that provides 24VAC power to the thermostat. However, some homes don’t have this wire. If your home doesn’t have a C wire, you’ll need to buy a Power Extender Kit to use with the thermostat.

The kit has a small device you’ll need to wire into your HVAC system. The device provides the power that the thermostat needs to operate.

However, you don’t have to worry about the C wire if you use the Ecobee smart thermostat. This thermostat comes with a power extender kit to make your work easier.

Expert tip: You should never try to install the power extender kit if you’re not experienced. A small error during the installation will damage your entire HVAC system. Thus, it’s advisable always to seek a professional for such installations.
