Battery-free, maintenance-free Bluetooth® button for Casambi smart+free lights. The energy for signal transmission is generated by pressing the button, meaning that no mains voltage connection or battery is required. The supplied frame (Jäger Direkt Opus 55 Inform) can be replaced by switch programs (internal dimensions 55x55 mm) from various manufacturers. Depending on the cover selected, 2 or 4 buttons can be freely programmed. The color temperature/dimming level of individual lights, groups or scenes can be controlled as desired. Configuration takes place directly in the app.
