So, why would you want a smart thermostat? The real question is, why wouldn’t you? A smart thermostat allows you to control your HVAC system using your phone or voice while allowing it to become more efficient over time!

Ecobee has taken a leaf from the Nest thermostat with a built-in feature to learn from your routine to create customized schedules. It can also recommend changes to your existing schedule based on your routine. Whereas Honeywell is a better choice for those who want to be able to program the settings to their liking.

Both smart thermostats are relatively easy to install. Though the ease of installation will likely depend on your skills and experience, you don’t need to call in a professional unless you have a very specific HVAC configuration. 

Ecobee claims their thermostat can be installed in under 45 minutes with no extra help. There is a video that you can follow that will guide you through the installation process. You can also find a detailed guide on the official ecobee mobile app. If all else fails, the company invites you to call the support team and ask for help!

Honeywell Home claims that their thermostat is just as easy to install as their competitors'. There is an installation guide available that you can follow closely for easy setup. There is a power adapter included in the package that replaces a C-Wire to provide a constant stream of power to the device. That makes the thermostat even easier to install and highly compatible with most HVAC systems. 

Overall, it appears as though both contenders offer quick and easy installation. If you’re worried about setting things up, you can’t go wrong with either option.

Style & Design

Sure, we’ll get to talking about the technical features and capabilities of these thermostats, but first, let’s discuss style and design. This is a category where both products really shine! 

The ecobee smart thermostat has a beautiful shape that is neither extravagant nor too harsh or boring. Its lack of sharp edges automatically makes it feel cosy, while its crisp glass display allows for easy viewing and programming. Overall, the smart thermostat will look quite, for lack of a better word, smart, in your home!

The thermostat offered by Honeywell Home is slightly less interesting to look at. The shape is nice and soft, and the white colorway will fit in well with any color variations on your wall. The beauty of the T9 smart thermostat is in its simplicity. If you’re looking for a thermostat that will blend in with the surroundings, this is a great option.

Though both thermostats are beautiful in their design, the Honeywell Home model is slightly underwhelming in comparison to the ecobee.

Programming & Learning Capabilities

Finally, we’re getting to the important stuff! Programming and learning capabilities are important features customers look for in a smart thermostat. 

The smart thermostat by ecobee can learn your daily schedule and even give you recommendations that will help lower heating costs. The occupancy sensor will automatically adjust the temperature when you leave the room/house, and again when you return. Programming the thermostat to follow a complex schedule can be tricky, but you can always ask the support team for help, or let the thermostat adjust the temperature automatically.

The T9 smart thermostat by Honeywell Home is quite the opposite. It cannot learn your schedule automatically, so you need to program it yourself. You can choose the temperature for each room manually or let the thermostat do that for you. It does so by using occupancy sensors to detect which rooms are in use. Naturally, the ones that are in use get the most comfort, be it heat in the winter, or cool air in the summer. 

Smartphone App

One of the features that make a smart thermostat smart is the official app you can use to control the device. Of course, both ecobee and Honeywell Home have their very own apps that make changing the temperature in your home easier than ever.

The ecobee app not only lets you control your indoor climate, but also offers a myriad of other helpful features. These include notifications sent when the system needs maintenance. You will also get a notification if the temperature in your house has become dangerously low which can lead to frozen or burst pipes. 

Honeywell Home lets you monitor the usage of all your Honeywell Home devices. You will get a handy reminder when you need to change the air filter, as well as when temperatures fall or rise way above the norm, leading to possible problems. Your thermostat can also determine when you’re home or away using your phone’s location. It can then adjust the temperature automatically and shave a few dollars off your electricity bill for the month.
