The smart wall switch allows for intuitive, direct switching and dimming of Zigbee products without the need for a smartphone or gateway. When combined with the Paulmann smik Gateway, individual configuration can be performed. Only with the corresponding Paulmann smik app can group buttons be assigned to specific rooms and scenes. Using the wall switch with another Zigbee gateway may be possible depending on the manufacturer, but this is not guaranteed by Paulmann. In this case, basic control of Zigbee lights via Touchlink is possible after integration.
