Z-Wave UP radio receiver ON OFF With the radio flush-mounted receiver (UP) you can conveniently link your light in if-then conditions using the Smart Home control TaHoma*, integrate scenarios or easily switch it on and off. The radio flush-mounted receiver is rounded off by the Z-Wave radio protocol. With this radio protocol you have 2-way radio at your disposal. This means that you receive feedback as to whether your light is on or off. The flush-mounted receiver is specially designed for light sources such as 230V LEDs, low-voltage LEDs with 230V transformers, 230V halogen lamps, low-voltage halogen lamps with 230V transformers, fluorescent lamps, light bulbs or alternatively ohmic consumers (e.g. radiant heaters). The radio flush-mounted receiver can be installed behind an existing (light) switch, button or optionally directly to the power supply. Due to its small design, the receiver can be easily integrated into a standard flush-mounted box.
