Use a smart button if you don't want to operate your Smart me products solely via the Smart me app. With one push of a button, you activate scenarios that you have programmed in the app. Activate multiple scenarios per smart button. For example, all lamps ON, all lamps OFF or all lamps in twilight mode. A smart button can be combined with all our smart bulbs and plugs. PLEASE NOTE: A smart button only works in combination with a Zigbee gateway
(Link ME). Connect multiple Smart me Zigbee products to one gateway.
