The Levven mobile app connects to all the Levven switches and controllers in the home via the Levven Q gateway.
Create a Room with two or more lights in the Levven app.
Using Rooms, all the lights in the area can be turned on or off with a single touch. Rooms can include all the lights in a room (e.g. a Kitchen Room), all the lights in an area (e.g. Outdoor Lights), or all of the lights in the entire home (e.g. a master room that turns all the lights on or off with one touch).
