🔧 Key Features
- Bluetooth Low Energy (BLE) control: Fast and secure wireless communication with Shelly devices.
- Four-button design: Each button supports single, double, triple, and long presses (up to 16 actions).
- Beacon mode: Sends signals every 8 seconds for presence-based automation.
- Strong encryption: Ensures secure communication with your smart home system.
- Compact size: Fits seamlessly into Legrand frames using the included adapter.
- Battery-powered: Runs on a CR2032 coin cell with up to 2 years of life.

🔍 Smart hint
- Assign multi-click actions to maximize functionality:
Single press → toggle lights.
Double press → activate a scene (e.g., “movie mode”).
Long press → dim or brighten lights.
Use beacon mode for presence-based automation, such as turning on hallway lights when you enter.
Pair with Shelly relays or dimmers to expand control beyond lighting, like blinds, appliances, or garage doors.
⚠️ Warnings
- No direct load control: The switch sends commands but does not switch power directly.
- OTA firmware updates: Must be completed properly; otherwise, the device may remain stuck in bootloader mode.
- Sleep mode: The switch enters sleep after 40 seconds of inactivity to save battery.
- Mounting caution: Ensure correct adapter use (Legrand in this case) to avoid loose fitting or misalignment.
