The registration code is key to a more sustainable way of living; you need it to set up the device.

Losing it is not the end of the world, but it is frustrating when you have set aside time to connect up your home.

Without the code, you cannot do certain things. You cannot:

  • Check-in with Alexa.
  • Use Siri.
  • Download the latest great sounds.
  • Be instantly alerted if a stranger tries to get into the house.

It can all be put right, but first, confirm if you have truly forgotten it and if nothing else is wrong. 

Have You Really Forgotten the Ecobee Code?

Perhaps the security code isn’t forgotten. Some circumstances would cause a Smart thermostat not to accept a code.

Here’s why your Ecobee thermostat may not accept your code:

  • It could be a simple typo or misreading.
  • It could be muddling letters and numbers like 1 and I.
  • It could be the letter o for a zero.

Making these corrections makes the code work. But, a code often doesn’t work because it is not meant to. It’s expired.   

Fixing Your Expired Ecobee Code

  • Go to the ecobee thermostat’s screen.
  • Tap the three horizontal bars in the left corner for the Main Menu.
  • Select Registration.
  • After the ‘2 steps left’ dialog box, go through the Wi-Fi setup.
  • Follow the instructions to generate the code.
  • Use the new code to confirm why the last code hadn’t worked.
