Pros
Pro Programmable from the thermostat itself
All of the functions of your phone can also be done right on the thermostat. If you frequently switch phones, or just prefer hardware controls this is a significant perk.
Pro Design is conservative, and looks like a regular thermostat
While most smart thermostats go the full mile when it comes to futuristic design, this Sensi thermostat takes a more traditional approach. Just by looking at it, you wouldn't be able to tell that this is a smart thermostat.
Pro Automatically works to reduce power usage
Instead of continuously heating and cooling, this thermostat can use a fan mode instead of full cooling to help preserve power while still providing adequate comfort.
Pro Notification support keeps you in the know
If there was an extreme temperature change, Honeywell lets you know. It can also notify you when it's time to change your air filter. Notifications like these are a nice addition, as it keeps you in the loop about what's going on with your house.
Pro Configurable schedule to suit your needs
You can schedule the settings for every day of the week through the dashboard. You can also edit your settings at any time.
Pro Beautiful interface
The interface is extremely attractive but also informative. It will tell you the indoor temperature and humidity as well as the outdoor temperature and humidity.
Cons
Con No automation
This thermostat doesn't offer any smart learning or automation. While it does allow you to program a schedule into it and adjust the temperature remotely, that's just about the extent of its smarts. It doesn't offer motion sensors or track your location in any way.
Con Old fashioned looking
Most smart thermostats look the part - they look smart. This one looks just like any regular old thermostat, including the clunky buttons, large physical body and monochrome display.
Con The user interface appears cluttered
While the UI is very functional, it appears cluttered as it tries to display a bunch of information all on the same display. On the main screen, there are 4 tabs on top, two buttons to adjust the setpoint, and it displays the current indoor temperature as well. On the left it displays current information such as date, time, weather conditions, and the status of the system.
Some will appreciate this layout for its functionality, but others will find it cluttered and not appealing.
Con Installation can be difficult
The tools you require aren't included, and depending on your HVAC system the installation can be tricky if you try to do it yourself.
Con Doesn't learn as much
While this smart temperature can learn, it doesn't learn as much as other smart thermostats. It relies more on programming.
