If you received a message that a controller serial number is already in use or not valid, the serial number is linked to another account. Here are a few reasons why this might occur:
- You may be trying to register a controller your contractor installed and added to his or her account. Contact your contractor for details on transferring your controller configuration to you. You can find additional details here.
- The contractor may have used a different email address for your controller or misspelled the email address. Verify with your contractor that the correct email address was used.
- The serial number is already linked to another person. Contact the original owner of the Hydrawise controller to release the serial number. Learn More
- You created your account under a different email address.
