How can I simplify the different IDs used to log in to multiple Gro controllers?
To configure multiple Gro Controllers you will need multiple Gro Accounts. A valid email address is required to create each Gro Account and you can only control one Gro Controller from one Gro Account.
Some email services like Google Gmail allow you to use special characters with your email address so that the addresses appear distinct, but will still go to the same Gmail account. This makes setting up multiple Gro Controllers more manageable.
For example, if you configured your first Gro device with the email ID firstname.lastname@example.org, you could then create a second email ID as email@example.com to log into the second Gro controller and then create another as firstname.lastname@example.org to log into a third Gro controller.
Unfortunately, you cannot log into multiple Gro controllers with the same email ID.
