Reconnect your Sensi thermostat to Wi-Fi

 

If you replaced your router, changed to a new Wi-Fi network, or updated your current Wi-Fi network’s password, you’ll need to reconnect your Sensi thermostat to Wi-Fi.

Connecting to Wi-Fi may be different depending on which Sensi model you have, and what type of phone you’re using to set it up. Find your product below and then find the instructions for your type of phone.

Sensi Smart WiFi Thermostat

 

iOS - iPhone/iPad

To reconnect using an iOS device, determine what type of Sensi you have first:

  1. On the thermostat itself, press “Menu”.
  2. Press “Connect”.
  3. What display do you see? There are 4 different options:
    • Display is blank
    • Display shows 00
    • Display shows 11
    • Display shows 22

 

DISPLAY SHOWS 11 OR 22:

  1. Your Sensi should be displaying 11 or 22 already. If it isn't, press "Menu" and then "Connect" again.
  2. On your iOS device, open the phone Settings.
  3. Tap Wi-Fi. Your phone should be connected to the 2.4GHz Wi-Fi network that you’re going to use with Sensi. If it isn’t, do so now, and “forget” any 5GHz Wi-Fi networks your phone may try to auto-join.
  4. Scroll down to “Set up a new device…” and tap your Sensi network name (i.e. Sensi-XXXXXX).
  5. In “Accessory Setup” you should already be connected to your 2.4GHz Wi-Fi network so tap "Next". This process may take up to 5 minutes.
  6. After it has joined, tap Done.

Your Sensi should be reconnected now. You may have to press “Exit” on the Sensi thermostat screen to get it to go back to the main screen. Check the Sensi app to make sure you can access it again.

Problems?

If you're having issues with this setup process, remove the Sensi face plate from the wall by pulling it straight towards you. Press "Menu" and then "Connect" again. You should see the display show "00" now. 

Follow "Display is blank or shows 00" instructions below for different setup instructions.

  11. Once you have the blue check mark next to the Sensi network, return to the Sensi app. Tap Next.
  12. Enter the Sensi PIN/password. If your Sensi screen shows 00, 11, or 22, the app will prompt you for the Security Code/PIN. The Sensi PIN/password is the Security Code that was on the back of the Welcome Guide.
