Description

Please Note: This model includes a standalone adapter—a back plate that allows the wall switch to be used as a handheld remote control without mounting it to a wall.

The Shelly BLU Wall Switch 4 connects to other Shelly devices via BLE (Bluetooth Low Energy) and features four buttons, each supporting multiple actions (single, double, triple, and long‑press). This gives you up to 16 distinct trigger options.

Unlike other Shelly wall switches, the BLU Wall Switch 4 requires no wiring and does not include a rear bracket for installing a Shelly module. Instead, it uses built‑in Bluetooth and can be configured through the web interface to wirelessly activate individual appliances, groups of Shelly devices, or fully synchronised Smart Scenes.

This model is designed primarily for use as a standalone, pocket‑sized remote control.
