Shelly BLU Wall Switch 4 wireless switch + adapter for Legrand / Shelly mounting frames

The Shelly BLU Wall Switch 4 is a battery-powered 4-button Bluetooth wall switch (remote control) that allows you to control your smart home. You can even create 2-way / 3-way switching without wiring. The switch communicates directly with Shelly modules, so you can control lighting or other electrical devices via Bluetooth. The switch is compatible with the Shelly BLU Gateway, so if the Shelly relays are too far away, the remote can still be used with that.

This variant has an adapter for Legrand compatible mounting frames and Shelly glass wall switch frames.
