The far-right tab on the setup page is the room editing tab. Normally this tab displays your RedEye room name. If you are using a RedEye Pro with at least one room defined, you will see a drop-down menu instead of a single room name. Selecting any item in the drop-down menu (including the root RedEye Pro) allows you to edit that room.
In this section you can change the name of your RedEye room, and also view its serial number. If you are editing a RedEye Pro room other than the root, there is an editable description field in addition to the name field. Click Save after you make changes to store them.
