By default, your dial switch is installed in a room and controls all of the lights which are part of it.

If you want your switch to control multiple rooms at once, or only certain lights... you can change this in the accessory settings.

• Go to the Settings page (button at top right corner of the home screen)
• Go to Accessories
• Select the switch which target lights you want to edit
• Tap on Targets
• Select the lights that should reply to this switch
