Download the Sensi app

The Sensi Smart Thermostat is a Wi-Fi enabled device. To install and configure your thermostat correctly, you must use the Sensi app. To start the installation process, download the Sensi app to your smart phone or tablet. It is a free download. The Sensi app requires the following Operating System (OS) software to download: Android (Google Play) version 5.0 or later iOS (Apple) version 10.0 or later

*Note that in the iOS store, the Sensi App will ONLY appear on an “iPhone only” search. On an iPad, change the search criteria in the App Store. 

Create an account

When you download the Sensi app, you will be prompted to create an account. This is required to access your thermostat remotely and use all the features Sensi offers. Use a valid email address and a password of your choosing to create an account. Remember this email address and password. Your Sensi thermostat will be linked to this email address once it is registered.

INSTALLING THE SENSI THERMOSTAT

  1. Installation Once you have downloaded the Sensi app, and have created an account, you are ready to install the thermostat to your wall and connect it to Wi-Fi. If no thermostats are registered yet, tap the “+” sign to add a thermostat. Then, choose which thermostat you purchased.
    • 1F87U-42WF series
    • ST55 seriesI Note: You can check your model number on the back of the thermostat faceplate.
  2. Install Path After creating an account, signing in and choosing your model, the app will ask you whether or not the thermostat is already on the wall. You will either choose “No, it needs to be installed,” or “Yes, it is on the wall.” The first option will walk through the entire installation process. If you did not have this thermostat professionally installed, choose this option. The second option is for connecting your thermostat to Wi-Fi only. If you have had a professional install your thermostat, and you just need to connect the Sensi thermostat to your home Wi-Fi network, choose this option. No, it needs to be installed. This option will walk you through the entire installation process, including identifying and connecting your wiring, as well as connecting to Wi-Fi. The Sensi app will walk through a step-by-step process for installation.
  3. Gather Tools and Package Contents Gather all the necessary tools for installation. Select your thermostat
  4. Turn Off Power Turn off the power to your heating and air conditioning system before handling your thermostat wires.
  5. Remove Old Thermostat Cover Remove the cover using a screwdriver or by pushing the pressure latch. Some covers pull off while others need to be released using a screwdriver.
  6. Photograph Your Wiring THIS IS IMPORTANT. The Sensi app will prompt you to take a picture of your existing thermostat and old wiring in case you need it later. This can be helpful for troubleshooting with our technical support team if necessary. The picture you take will be saved to your camera roll or photo gallery.
  7. Throw Away Any Jumper Wires Sensi has a jumper wire built into it, and you will not need any jumper wires from your old unit.
  8. Choose Wire Terminals Choose the terminal labels that have wires attached to them on your old thermostat here. The app will tell you if you have a valid configuration. If you are getting an invalid configuration message you can learn more about compatibility at sensi.emerson.com/en-ua/compatibility. A c-wire, or “common wire”, is required for heat only, cool only & heat pump applications. You can learn more about installing a c-wire at sensi.emerson.com/en-us/c-wire.
  9. System Type Select what type of system you have.
  10. Label Your Wires Using the provided wire label stickers, label your wires by removing one wire at a time.
  11. Disconnect Wires and Remove Base After all of your wires are labeled, remove the old thermostat base from the wall.
  12. Install Sensi Base Use the provided mounting screws and secure the Sensi base to the wall.
  13. Connect the Wires Once the Sensi base is mounted and secured on the wall, insert the wires into the terminals. Simply push the wires into the terminal slots. Use a screwdriver to secure each wire in place
  14. Attach Cover Push the front display onto the thermostat base.
  15. Turn On Power Turn the power to your system back on.
  16. Connecting to Wi-Fi This portion of the installation guide covers how to connect your thermostat to Wi-Fi. If you chose “No, it needs to be installed,” the app will provide instructions for installing and wiring your thermostat before you connect to Wi-Fi. If you had your Sensi thermostat installed by a professional or if you have already installed and wired your Sensi thermostat yourself, but have not yet connected to Wi-Fi, choose “Yes, it is on the wall.” The app will jump right into connecting your thermostat to Wi-Fi.
    1. BROADCAST SENSI NETWORK On the thermostat, press Menu, and then Mode. The Wi- Fi icon in the upper left-hand corner will flash, and 00, 11, or 22 will be displayed in the middle of the thermostat. This determines what Sensi version you have.
    2. CONNECT YOUR SENSI THERMOSTAT TO YOUR WI-FI NETWORK WITH THE SENSI APP Follow the step-by-step instructions in the Sensi app. The Wi-Fi connection process will be slightly different based on your device’s operating system (iOS/Android), Sensi app version, and the version of Sensi thermostat that you have. If you are connecting with an iPhone/iPad, and you see 11 or 22 displayed on your screen, you’ll have the option to connect your thermostat with Apple HomeKit. After connecting to the Sensi network, you’ll enter the Sensi password, printed on the Welcome Guide (or found on the back of the thermostat face plate as “Sensi Security Code”). Then you’ll connect to your Wi-Fi network.
  17. Name Thermostat You can select a name or choose a custom name for your thermostat. Press “Next” to continue.
  18. Register thermostat After successfully connecting Sensi, the app will prompt you to register the thermostat. You can either choose the “Locate Me” option or fill in your street address, city, state, zip code, country and time zone manually. Press “Next” to continue.
  19. Contractor Information If a contractor professionally installed your thermostat, and registered as a Sensi partner, they have the option to input their phone number here. If there is not a registered number available, simply hit “Next” to continue.
  20. Start Using Sensi Congratulations on successfully installing Sensi. Press “Start Using Sensi” to open the main screen of the app.

SENSI 1F87U-42WF, ST55 SMART THERMOSTAT TROUBLESHOOTING 

Connecting to Wi-Fi Troubleshooting

If you’re having trouble connecting to Wi-Fi, here are some tips to try:

  • Make sure the Sensi app is up-to-date and running the latest version available in your app store.
  • Reboot your smart phone.
  • Reboot your router by unplugging it from the wall for a few minutes and then plugging it back in.
  • After your router reboots, and your Wi-Fi network has internet access again, make sure that your phone is connected to your 2.4GHz Wi-Fi network.
  • If you’re on an iPhone, make sure Keychain is On, and Home Data is allowed for the Sensi app.
  • If you’re on an Android, go into your phone’s Advanced Wi-Fi Settings and turn off the “Switch to mobile data” feature. (Depending on your Android, it may be called “Smart Network Switch” or “Avoid poor connections.”)
  • It may be easier to just turn “Mobile Data” off completely for setup. You can find this in your Connection settings.
  • Try another smart phone or tablet. Simply download the Sensi app and sign into the app using the email address and password you used when you created your account.

Reconnecting to Wi-Fi

If you replaced your router or changed your Wi-Fi network password, you will need to reconnect your thermostat to Wi-Fi. This is different depending on what smart device you are using. Please see our support article for more information on how to reconnect.
