Registering your ecobee thermostat is essential so you can use all the benefits this thermostat offers. We searched the internet for thorough instructions on finding the code and finishing the device's registration process.

What To Do If You Can't Find Ecobee Thermostat Registration Code

Access the main menu button on the bottom left side to get your thermostat's registration code. If you don't see the menu option saying "Registration," you will not be able to find your registration code because it means your Ecobee has already been registered. To change your device's ownership and see the registration code, follow these directions:

  1. Turn your Ecobee thermostat on and ensure it is connected to power.
  2. Click your thermostat's "Main Menu" icon, which looks like three horizontal lines.
  3. Select the "Settings" icon.
  4. Click Reset, then select "Reset Registration."

After doing this, open the Main Menu again, then click Registration. Then, it will say "2 Steps Left" under the registration icon to take you to the Wi-Fi configuration screen and connect to your home network. Finally, your device will generate a code.

What To Do If A Message Says Your Ecobee Registration Code Is Incorrect?

Inputting an expired code will get you a message that the code is incorrect. Your Ecobee registration code expires after about an hour, so you must re-generate the code if you need it. Just tap the Main Menu and click Registration again.

If your code hasn't expired, try rechecking if you've filled in the correct digits. The code may have letters that look like numbers. For instance, you may misread "I" as "1" and "O" as "0". Try using "I" and "O" if this is the case. If your code contains 1 and 0 already, try doing the opposite. 

Can You Add More Than One Account For Your Ecobee Thermostat?

There can only be one Home Owner for an Ecobee thermostat. However, Ecobee also introduced Family Accounts, so up to 15 members can access the device through their smartphones. But, administrative privileges, including account changes, removal and registering new thermostats, and enrollment in eco+ services, are only limited to the homeowner.

Family members can see home information, control the thermostats, and invite new members to join. The Home Owner has to set up a Family Account in the Ecobee app to invite family members to join. Do this by following these instructions;

  1. Open your Ecobee app, then click "Account."
  2. Tap "Manage Homes."
  3. Click the Home where you want to invite a new member.
  4. Tap "Home Members."
  5. Click the Invite New Member button.

The most probable reason you can't find your ecobee thermostat's registration code is that the device may still be registered to an owner. You can quickly resolve this by resetting the registration process.

After, you can then use that registration code to control the device's settings through your smartphone. Make sure you already have an Ecobee account using your phone or Ecobee's web portal to be able to regulate your thermostat settings.

When registering your thermostat, if you get a message saying that the code you input is incorrect, it may be because you have mistyped it. However, if that isn't the case, change the letters in the code your device shows into their corresponding numbers or vice versa.
