Shelly Blu Wall Switch 4 Zb – Remote control, 4-button, Bluetooth, Zigbee, white

The Shelly BLU Wall Switch 4 ZB Standalone is a battery-powered four-button wireless smart home remote control with Bluetooth Low Energy and Zigbee 3.0 communication. It can be used to control lighting, roller shutters, blinds, garage doors, smart devices and automation scenes. Each of the four buttons can distinguish between single, double, triple and long presses, allowing up to 16 different actions to be assigned in total.

The switch requires no wiring and is powered by a single CR2032 coin cell battery, which according to the manufacturer can provide up to 2 years of operation under typical use. It can be mounted on a wall using adhesive or screws, is compatible with several common switch frame ranges, and can also be used as a portable remote control.

The device supports both Bluetooth LE and Zigbee communication. In Bluetooth mode, a compatible Shelly gateway or Shelly device acting as a gateway is required for use with the Shelly Smart Control system, while in Zigbee mode it can be connected to a compatible Zigbee network. The “Standalone” version refers to its physical use as an independent remote control; Bluetooth or Zigbee connectivity is still required for smart home functions.
