Expert Reviews


What experts liked

There's an LED strip on the top of the device that glows blue when you use an Alexa voice command and red when the built-in microphone is turned off.
A strong app and an excellent touchscreen interface on the device itself make it supremely easy to use
The Ecobee SmartThermostat adds features to its built-in Alexa speaker. It has a redesigned temperature sensor and works with Google Assistant and Siri -- all for the same $249 price.

This wifi thermostat performed very well on its own merits, earning one of the top scores we have seen so far by its good performances in our ease of use, remote access, and installation tests.
The SmartThermostat boasts a new touchscreen display that is clear and reasonably bright.
In addition to working with Amazon’s Alexa, the SmartThermostat, like the Ecobee4, supports Apple’s HomeKit platform and Google Assistant, plus IFTTT and Samsung’s SmartThings, so it can integrate with most homes regardless of which voice assistant you prefer or platform you use.
One particularly useful feature enabled by SmartSensors is something called “Follow Me.” This uses the sensors to detect which rooms in your house are occupied, and adjust the temperature accordingly, depending on your current comfort setting.
Because it has Alexa built in, you don’t need a separate Echo speaker to control it by voice, and if Alexa isn’t your smart-assistant choice, this model also works with Google Assistant and Apple HomeKit and Siri (although they are not built in).
The ecobee also has a humidity sensor within the base. If you have a whole house humidifier or dehumidifier, it can be controlled by this thermostat.
The other big feature that the SmartThermostat includes is a built-in (and fully functional) Amazon Alexa voice assistant. The unit has microphones that allow far-field voice recognition.
Excellent smart home integrations

What experts didn't like

At $249 it's a bit pricey
Alexa integration can be annoying if you already have an Echo (or other Alexa-powered device) within earshot
Depending on where your thermostat is located in your home, it might not be in an ideal place for an Alexa speaker.
-
Lackluster performance in our accuracy tests, could be more intuitive to use
If your system lacks a C-wire connection, a power extender is included, which makes for a more complicated process
The new remote sensor is nicer to look at than the prior model, but I’m disappointed that it doesn’t add the ability to measure humidity; it still only measures temperature and detects motion.
If your thermostat wiring doesn’t have a c-wire (what’s a c-wire?), setting up the ecobee3 will require an extra step.
Requires at least 3 thermostat wires — only works with a common wire or additional hardware
By far the biggest flaw we encountered with Ecobee is how long it takes to adjust to Home from Away, or vice versa, if you interrupt the regular schedule.
