Sensi Thermostat App - Everything You Need to Know

The Sensi thermostat app is compatible with both, your Apple iOS and Android phones.

It allows you to configure settings on the Sensi thermostat remotely. Even if you have two separate thermostats installed on two floors, you can manage them from the app. The interface has separate upstairs and downstairs modes allowing you to control the temperature from any location within the house. Or even when you’re outside. 

The Sensi app has all the features you may need to use the thermostat seamlessly, right down to the installation. Not only does the app provide you with a set-by-step tutorial with images, but you can also click pictures. This feature is helpful when you’re executing a DIY replacement because you can record the existing wiring setting. Next, you’ll connect the wires to the correct terminals of your new thermostat without any confusion. 

You can use the app to change the configurations needed for your heating, cooling, and ventilating units. Since the Sensi smart thermostat also integrates your humidifier, you’ll find the settings in the app to change as needed. 

Pros of Getting the Sensi Smart Thermostat
  • Easy to install, you can complete the Sensi thermostat setup within 30 minutes or less.
  • Standard dimensions, which means that you need not worry about repainting and touching up the wall behind the new installation.
  • After purchasing the product, you can first download and install the Sensi app on your phone. The app will provide a detailed step-by-step guide for a DIY installation. Accompanying images are also available to guide you through the process.
  • Since the Sensi smart thermostat is Wi-Fi-enabled, you can warm or cool your house from a remote location. This feature ensures that you always come home to the ideal ambient temperatures.
  • It does not require you to change batteries to keep it running since it draws power to your home’s electricity supply.
  • You can expect significant power savings. The thermostat enables you to set a specific HVAC schedule for each day of the week per your family’s needs. 
  • With a quick glance at the thermostat, you can tell the specific function it is running thanks to the different colors it displays.
  • The Geofencing mode detects when your phone has left a particular radius and automatically lowers the house temperature by 4 degrees. 
  • Includes the ability to lock the screen so kids can’t accidentally change the settings.

The thermostat sends you alerts to warn you of any possible issues with your HVAC systems. You can also get maintenance reminders, for instance, when it’s time to change filters.

Cons of Installing the Sensi Smart Thermostat

  • If you don’t have a C or common wire installed, you’ll have to call in a professional electrician. This issue typically arises in older homes. The contractor will run a new wire for you before you can install your new thermostat.
  • Customer support is not all that efficient. If you have any issues, expect to deal with long wait times until you can speak to an agent. 
  • The Sensi smart thermostat does not include the AI-driven memory option that records your heating and cooling habits. Users may not be able to track and analyze their power usage to work out how to economize on bills.
