The ecobee4 is the better all-around thermostat option for most people, with built-in Alexa support, HomeKit support, and better external room sensors. The HomeKit support helps fill in some of the automation gaps between the ecobee4 and the Nest, and also gives you more options when setting up your smart home.
Still, if you want a smart thermostat that learns your behaviors, the Nest is great. As it learns, the Nest creates an automatic schedule, and you can still make temperature adjustments either on the thermostat itself or with Alexa or Google Assistant.
There are a significant number of similarities between the ecobee4 and Nest thermostats, and both are great picks. But there are also key differences of which it’s essential to be aware, such as the fact that the Nest is a learning thermostat. It learns how you like your house to feel over time. Additionally, it can automatically set itself into Eco Temperature mode when you’re away from your home (with location data provided by the Nest app on your phone) to save energy.
The Nest will also offer suggestions for energy-saving settings that could help you save money on your heating and cooling bills.
The ecobee4’s most significant advantages come in the form of its available options. Like the Nest, the ecoobee4 thermostat works with both Google Assistant and Alexa. Alexa is built right into the ecobee4, which features multiple microphones so it can hear your commands. Beyond those two assistants, the ecobee4 also works with Siri thanks to its support for HomeKit. HomeKit support lets you integrate the ecobee4 with your other HomeKit accessories and scenes, something you can’t do with the Nest.
The ecobee4 also has better external room sensors than the Nest. These sensors detect, not only the temperature of each room in which they’re placed but also whether or not anyone is in those rooms, letting you deliver heating or cooling to those rooms as needed.
|Power||Wired||Wired or Battery|
|Remote sensors||Yes (Sense temperature and room occupancy)||Yes (Sense temperature)|
|Learns habits over time||No||Yes|
|Works with Amazon Alexa||Yes||Yes|
|Google Assistant support||Yes||Yes|
|Amazon Alexa built-in||Yes||No|
The truth is that no matter which of these thermostats you pick, you’re going to be getting a quality product. And while the two are quite similar in a lot of ways, their differences will appeal to different people. Want a thermostat you don’t have to think about? Get the Nest. Want something with a virtual assistant built-in? Get the ecobee4.
Still, I’d recommend the ecobee4 for most people. It’s got Alexa built-in which is great for direct control, while also working directly with HomeKit, letting you add it to your scenes with other HomeKit accessories or control the ecobee4 with Siri. It’s external sensors, placed in each room, also tells you if people are in that room, letting your heating or cooling systems deliver what’s needed more efficiently.
A great thermostat with a lot of options.
With Amazon Alexa built-in and support for Apple’s HomeKit, the ecobee4 offers a lot of options for control and automation, along with room sensors that handily beat the competition.
An intelligent thermostat that learns what you like.
Learning your temperature adjustment needs over time, the Nest Thermostat’s automatic schedules make it a “set it and forget it” sort of appliance that takes some of the worries out of heating and cooling your home.
