The feature that I like most is its reporting; I can see energy consumption and all previous reports that help a lot to understand when it is consuming more, that support to decide about a preferred mode for maximum saving on energy bills. Its intelligent sensors can sense when you are not at home to turn off all the devices, and when you get in, they can automatically enable the right mode on your ecobee4.
It may take some time to learn from your preferred setting, but once it gets all it will provide you with comfort that you expect. It’s Alexa enable so you can directly instruct Alexa to turn it off, or even you can change the setting and mode through Alexa. You may add additional sensors to regulate more zones.

During my research, I found that every system that is being used in our country is compatible with the thermostat. If you are living in an area where you need a heat-only or a cooling only solution then there is no need to spend extra budget on the costly solutions. This product works best with singular systems and also will help you to control the cost of electricity.
Scheduling and app control are features that are hardly possible in this price, but Emerson is offering these state of art features that will bring a lot of ease in your life. I figure that there are some advanced features that one might like when working with heat and cooling system, but in case of a singular system that features does not have any significance. You do not need to hire an electrician for installation; it comes with a complete manual that elaborates how to install it, surely help you to DIY.
