Expert Reviews

What reviewers liked

The ecobee3 looks shockingly like the ecobee4, which I’ve also reviewed. It’s black with a 3.5 inch full color LCD touchscreen in 230 by 480 pixels. The ecobee3 lite will work in your home whether you have gas, oil, electric, or dual fuel heating and cooling, and a c-wire is not required— that’s why the ecobee3 lite includes a Power Extender Kit.
Excellent app integration allows you to control the temperature straight from your phone. Interface is easy to see and use.
A responsive touchscreen and integrations with Amazon Alexa, Apple HomeKit, Samsung SmartThings, Wink and IFTTT give the lower-priced $169 Ecobee3 Lite Smart Thermostat serious appeal.
The ecobee3 lite's most unique feature is its optional remote sensor; no other thermostat brand in our comparison has anything like it. Remote sensors wirelessly communicate with the thermostat to detect temperature and motion in other areas of your home, giving it more complete information.
An Ecobee without room sensors is still a superbly designed thermostat with a great user interface and a terrific app—but so is the Honeywell Lyric T5, which you can buy at Amazon for just $110.
Using the Ecobee3 Lite is as simple as you'd hope. Just slide a finger up and down on the right side of the 320-x-480 display to adjust the temperature of whichever mode you're in: heat, cool or auto.
I like that Ecobee’s base plate has a small leveling bubble, to ensure that you’re not installing it on an angle. Next, attach the face to the base plate, and the Ecobee3 Lite should power up.
All-cause with the savings, you would make. Sensors send information to the thermostat about various factors like your presence in the room or the temperature.
Has password protection to prevent unauthorized changes using the thermostat - app remains fully capable.
You will like the way it reads and transmits the data to your phone remotely. This makes it reliable.
The thermostat works with room sensors helping maintain a constant temperature throughout. It can measure both the occupancy of the room and temperature to switch comfort mode when at home and help save energy when away.
Comes with an easy to change built-in schedule, so there’s no “learning” period to go through
The installation is pretty simple, Installation guide comes in a box with the device and if that is not enough there are more instructions on the Ecobee website or in the mobile app, and for those aren’t handy, there is telephone technical support which guides you step by step or you can even schedule a professional to come and install Ecobee3 smart thermostat for you.
We love the way Ecobee3 Lite Thermostat reads and teaches itself to adjust home temperatures. In its ​primary mode, the Ecobee3 lite takes readings from all the sensors and averages them out, making sure all parts of the home are equally warm.
There is a special ecobee app for the users of Android and iOS devices. They can control the temperature and operate the machine from remote locations through a smartphone.
Ecobee3 is the most suitable smart thermostat to help you save energy (and money).

What reviewers didn't like

Reliability is questionable in the event of a power failure.
Smart" is a bit of a stretch for the Ecobee3 Lite, since it doesn't rely on activity-tracking sensors or any other sort of adaptive tech to learn your routine. $169 is still a lot to spend, especially on a programmable thermostat.
It does not come with a remote sensor.
Being a budget-minded device, the Lite lacks the terminals required to control advanced HVAC components, such as humidifiers, dehumidifiers, and ventilators
Missing from the Lite is a component that some of the flagship's more advanced features relied on: remote sensors.
No native geofencing
HomeIQ reports could use some improvements, such as being able to see them in realtime instead of having to wait for a full month to finish
You only get two sensors with the initial purchase. Requires you to buy more.
Some of the features are very complex to understand.
