Description

The Shelly BLU Wall Switch 4 is available as a standalone unit. The Shelly BLU Wall Switch 4 communicates with other Shelly devices via BLE (Bluetooth), offering four physical buttons that each support multi‑click input, including single, double, triple and long‑press actions. In total, the switch can deliver up to 16 distinct triggers.

Unlike other Shelly wall switches, this model requires no wiring and includes no rear bracket for mounting a Shelly relay. Instead, all intelligence is built directly into the switch itself. Through the web interface, it can be configured to wirelessly activate individual appliances, control multiple Shelly devices at once, or run fully synchronised Smart Scenes across your home.
