Q: I've heard you need a Registration Code in order to register a Smart Si thermostat to the portal. What's involved here?
A: A registration code is needed to add the Smart Si thermostat to your portal. Once the Si is connected to your Wifi network, the thermostat will display a 4-digit code (numbers and/or letters). Next, visit www.ecobee.com, click on the LOGIN button and then click the REGISTER THERMOSTAT link. You’ll be prompted to ‘Create a New Account’ or ‘Register to an existing account’. Once your account is setup, click the ‘Add Thermostat’ link in the portal and enter the registration code given to you previously. If successful, a message will appear on your thermostat confirming you’ve registered the thermostat. Click ‘Ok’ to complete the activation.
