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 Gira and (Schneider Electric's) Merten compatible mounting frames.

Key features:

• 4-button design: Can control up to four circuits simultaneously, so you can control multiple lights or devices with a single switch. Or you can use it for scene triggering.
  
• Functions: each button can distinguish between single, double, triple, and long button presses, and long button press release.
  
• Bluetooth connectivity: Does not require a Wi-Fi network or gateway when connected directly via Bluetooth to any of the Shelly Plus, PRO or GEN3 devices, using them as gateways.
  
• Energy-saving solution: The switch operates at extremely low power consumption, contributing to increased energy efficiency and long battery life.
  
• Easy installation: Compatible with standard wall boxes, it is quick and easy to install, the back of the fitting is flat so it can be fixed with double-sided adhesive (adhesive not included).
  
• Discreet design: Its clean, modern look will fit into any interior while remaining functional.
