Shelly BLU Wall Switch 4 ZB DK - White

The Shelly BLU Wall Switch 4 ZB DK is a battery-powered wall switch with four buttons, designed for Danish wall-mounting standards. It comes with a frame and double-sided tape for direct surface installation, and the frame can be removed for integration into existing switch programs. The switch can control lighting, blinds, garage doors, scenes, or other automations. The included CR2032 battery provides a lifespan of more than 5 years. Each button supports up to four actions: single press, double press, triple press, and long press. The device supports full local pairing with Shelly relays, dimmers, and shutter controllers – no app required. For advanced scenarios, it can be connected to Shelly Smart Control. The Shelly BLU Wall Switch 4 ZB DK uses Bluetooth for fast response and includes built-in Zigbee for integration with third-party Zigbee platforms. All Shelly BLU devices require a gateway for network access. Any Shelly Pro, Gen3, Gen4 device, or the Shelly BLU USB Gateway can serve this purpose. If you already have a Shelly device on your Wi-Fi, it automatically acts as a gateway for BLU devices. Features. Compatible with Home Assistant, Homey, and systems supporting BTHome.
