1. Tap on the name of the light within the main Dashboard
2. Then tap on the three horizontal 'dots' in the upper right-hand corner
3. Tap on the existing name
4. Delete the existing name, type in the new name, and tap 'done'.
5. Tap Done in the Menu of the settings screen, and the name will be saved
Note: You can also move the light to another existing group or location, or create a new group or location, by tapping the group name.
