Have you been looking for a smart thermostat for your home? Something that is capable but not entirely dependent on you? Something that doesn’t cost much but still offers a good performance? Well, Ecobee brings to you the Ecobee4 Smart Thermostat with a wide range of features starting with the occupancy, temperature and a whole lot of other sensors. It even provides you with a good amount of voice control, and while you can’t change the voice commands, you can always use the simple and simultaneously elegant phone and web apps. And finally, with a good automatic adjustment capability the Ecobee4 will make sure you have the best smart thermostat experience.

Why We Like It – Ecobee4 Smart Thermostat

Making power saving all the more easier and efficient, the Ecobee4 Smart Thermostat successfully rises beyond its predecessor the Ecobee3 lite Smart Thermostat. It comes with built in temperature, humidity, occupancy and even proximity sensors that automatically change the temperature to your own needs. Doubling as an Amazon Alexa speaker and also including Apple HomeKit and Samsung SmartThings, the Ecobee4 offers you almost everything you need within a small touch display thermostat that can easily be controlled via either voice or the phone and web app. And so, with all that as well as an included PEK(Power Extender Kit) for setting up, the Ecobee4 Smart Thermostat is something that is definitely worth the price for many of you out there.

  • Good range of app and control support
  • Included PEK
  • Occupancy Sensor and pre-set adjustment capabilities
  • Voice controls cannot be adjusted


Offering you a good number of sensors ranging from the remote temperature and proximity sensor to the humidity and occupancy sensors, the Ecobee4 makes sure you have the best environment at home whilst also saving up on cost, with the right adjustments at the right time. Not to be worried, as unlike some other smart thermostats, the Ecobee4 won’t turn your room temperatures to freezing cold or sweating hot temperatures in the middle of the night. The additional remote sensors that can be placed in different rooms away from the thermostat, will take into account your presence as well as a whole lot of other factors before sending in the data to the thermostat through WiFi. You can compare the Ecobee4 with the one in our review on Nest Labs launches second-gen learning thermostat.

While these automatic temperature changes are present, you can also control your smart home away from home through your phone and web apps provided to control them as you see fit. Also keep in mind that you can set ‘Home’, ‘Away’ and ‘Sleep’ schedules for the thermostat, to keep the temperature of your home to certain baseline comfort settings depending on the time. You can also set reminders to alert you when you need to change the filters or when the temperature gets too extreme. And so with that as well as the ‘follow me’ feature which is useful if you get the additional room sensor, the thermostat will automatically set a room temperature depending on where you are.

Furthermore, when it comes to the app integration, the Ecobee4, offers both Samsung SmartThings and Apple Homekit, and even comes with a built-in Alexa speaker, which allows you to use Alexa throughout your home without reaching for your phone or device. However, if you already have an Amazon Echo, Echo Dot, Google Assistant or Google Home system in your home, it isn’t that useful and without Amazon’s ESP feature, it will respond to your voice either way. Overall, it allows for a good amount of control for your smart home devices, but without any form of adjustment capability for the voice commands, you’ll have to learn them by heart. And if you do want to use the voice commands, make sure to place the Ecobee4 Smart Thermostat somewhere in the middle of the home, where you frequently pass through.

Finally, when it comes to setting up the Ecobee4, you’ll be happy to know that even though it comes with a C-Wire to operate, with the added PEK(Power Extender Kit) it can easily be set up without having to rewire your home’s HVAC system. And while you can set it up yourself through some instructions, if this is a first and new thermostat for your home, having a professional to help with the wiring may be more convenient. After that, you simply connect it to your WiFi and you have yourself a smartly controlled home.


Having a touchscreen display unlike the Honeywell Home Thermostat, the Ecobee4 is a nice addition to your home decor. It has a flat glowing display with a black body and added with the blue light for indicating when listening to you, it does indeed add a bit of nice aesthetic. Apart from that, despite having the microphone and speakers on the back of the thermostat, the Ecobee4 performs nicely, without drawing much attention to it, but still giving off a nice look when noticed.


Priced at about $250, the Ecobee4 Smart Thermostat is most definitely not the most affordable thermostat out there. But, offering you both performance and a design that is sleek but doesn’t stand out unlike the Emerson Sensi Touch, the Ecobee4 may earn its place among one of the best thermostats out there. It is also pretty durable and also being easy to set up with the PEK as well as the C-Wire connection, it makes for a pretty great value product.

While it may not be the most affordable thermostat out there, providing you with good sensors, easy controlling methods through the phone and web app, as well as some pretty great quality additional sensors, the Ecobee4 Review remains unanimously great from customers at amazon com. It offers you great app integration with Samsung SmartThings, Apple Homekit as well as built-in Alexa. And added with the easy set up process, sleek design and the flexibility of not needing constant attention, the Ecobee4 Smart Thermostat remains to be one of the best smart thermostats out there.
