To add a new space or edit an existing one on your mobile app, tap "Settings" and under "Home Settings", tap "Appliances & Outlets". It'll open a new screen and at the bottom click on "(+) Add" to add a new space.

From there, you'll see other pre-set rooms such as kitchen, utility room, bathroom, etc. You can also customise a room and appliance, and name this whatever may suit. 

To delete/edit a room space, click on the "pen" right next to the room name. Once you've done that, you'll be able to delete or amend the room name.
