The question often arises: “What is the difference between Ecobee4 and Ecobee 5?”

Ecobee 4 and Ecobee5 are two smart thermostats from the same company. Both models have been released in 2016.

Both devices offer remote access to other people through their smartphone app. Smart Thermostat Control allows users to set temperature control while away from home, see what temperature that you want at home even while not there or schedule temperature changes throughout the day that will be automatically overridden by the GeoSense function.

These Thermostats runs on a far-field sensor technology which helps in understanding whether someone is present in the room and can automatically adjust to different settings on a daily basis.

Ecobee 4 vs Ecobee 5 Thermostat: What is the difference?

So we can conclude that they both offer remote access and smart functionality. To discover what else separates them, read the rest of this article.

Ecobee 4 was released in 2016 while Ecobee 5 came out one year later, in 2017. The first model works on a set schedule while the other one uses artificial intelligence for automated programming according to habits and preferences. Removing manual overrides from schedules has lead users to be more efficient and save up to 23% on utility bills.

Alexa Feature Comparison

Although both smart thermostats feature a built-in Alexa as well as many similar features (like controlling your home’s temperature with simple voice commands) like calling, messaging, and announcement), the performance of the Alexa addition might be different.

Ecobee 4 comes with far more skills than Ecobee 5, as you can also take advantage of the Alexa calling, messaging and announcement features.

For example, I liked how I could “announce” to my family members that dinner is ready without having to leave what I was doing at the moment. Just by saying “Alexa, announce that dinner is ready” or “Alexa, tell The Family that dinner is ready”, everyone within earshot will hear me loud and clear!

Microphone Feature Comparison

In terms of acoustics, Ecobee 5 comes with a microphone that is far more powerful than the one that you can find in its predecessor.

This means that thermostat will be able to hear your voice commands from a far greater distance and even better understand them on a consistent basis.

In contrast, Ecobee 4 has an analog-style microphone which is unable to perform as well as the digital mic found in Ecobee 5.

Size & Construction

In terms of the design, both Ecobee 4 and Ecobee 5 look very similar to each other. Both sport the Ecobee “squircle” shape and come with almost identical dimensions, a sleek LCD display, and a single black color option.

Ecobee 4 and Ecobee 5 share almost identical construction characteristics, made up of a matte-finish plastic back and a glossy front face.

The only noticeable difference in terms of physical appearance is the display’s orientation. While both devices use white text on black background for their LCD screens, the Ecobee 4 features a portrait-style orientation while its successor uses landscape mode.
