Shelly BLU RC Button 4 ZB – Four-button remote control, Bluetooth, zigbee, white

The Shelly BLU RC Button 4 ZB is a compact, battery-powered, wireless smart button that offers fast and flexible control for Shelly-compatible smart home devices via Zigbee and Bluetooth Low Energy connections. Equipped with four separate buttons, each capable of handling multiple event types (single press, double press, long press), this device is perfect for triggering lights, scenes, automations, or custom functions.

One of its key advantages is its completely wireless operation. It runs on a CR2032 coin cell battery, which can last up to 2 years. Its compact design and included magnetic holder allow easy mounting on walls, wall switch boxes, or flat surfaces.

The Shelly BLU RC Button 4 ZB is ideal for users of Zigbee-based smart home systems who need a quick, reliable, and low-power physical controller. Bluetooth LE simplifies the initial pairing and configuration, while Zigbee ensures stable and energy-efficient daily operation.
