The Zigbee 3.0 Single Adapter in matte chrome allows for targeted control of individual spots as well as group switching within a URail system. It is simply mounted between the rail and the spot to be switched. Due to its delicate design, it is hardly noticeable. The system can be smartly planned from the beginning or transformed into a smart system with the help of the Single Adapter. Every URail system has the potential to be smartly controlled. Note: This item is not compatible with all fixed LEDs and LED light sources and only works in conjunction with continuously dimmable lights. The dimmer compatibility can be found in the technical specifications of the lights/light sources.
