RGBW Controller Shelly RGBW2 Wireless

The Shelly RGBW2 Wireless is a compact Wi‑Fi operated RGBW controller designed to convert standard 12/24V DC LED strips and fixtures into smart, remotely controllable lighting. With physical dimensions of 43 mm x 38 mm x 14 mm and available in blue and yellow finishes, this module fits flush into many installations and connects to a home network to enable control from a smartphone, tablet or compatible home automation system.

Advantages

The unit supports both RGB+W configurations and four independent single‑color channels, enabling flexible color mixing and white channel control. Wireless connectivity over Wi‑Fi provides direct access from mobile devices without requiring additional hubs. Its small size allows for installation inside switch boxes or behind fixtures, and it is suitable for centralized control of multiple lighting zones. The controller also provides the ability to switch or dim lighting remotely and to integrate simple automation scenarios.

Suitable for (tasks / use cases)

• Converting 12V or 24V LED strips to smart RGBW lighting
• Controlling RGB+W or up to four single‑color LED channels
• Retrofitting smart control into existing light fixtures or switch boxes
• Remote switching and dimming via smartphone or tablet
• Integration with home automation systems that use Wi‑Fi devices

When it may not be suitable

The Shelly RGBW2 requires a stable Wi‑Fi network to provide full remote and automation functionality; environments with unreliable Wi‑Fi will limit its capabilities. It is designed for low‑voltage DC LED installations (12/24V) and is not suitable for direct connection to mains AC LED fixtures without an appropriate DC power supply.

Key specifications

• Power input: 12 V DC or 24 V DC
• Control type: Wi‑Fi (wireless)
• Supported outputs: RGB+W or four independent single‑color channels
• Dimensions: 43 mm x 38 mm x 14 mm
• Available colors (housing): blue, yellow

How to use

Install the Shelly RGBW2 near the LED strips or fixtures, ensuring correct connection to a compatible 12 V or 24 V DC power supply and to the LED output channels according to the LED configuration. Connect the device to the local Wi‑Fi network using the Shelly mobile application or the device's web interface, then configure channel assignments, brightness limits and scenes as needed. After setup, control lighting directly from the app, integrate with voice assistants or include the device in automation routines. Follow local wiring rules and disconnect power before making electrical connections.

What to consider before purchase

• Confirm your LED strips or fixtures operate at 12 V or 24 V DC
• Ensure you have a stable Wi‑Fi network at the installation location
• Check physical space to accommodate the controller's 43×38×14 mm dimensions
• Verify the controller's output configuration (RGB+W or four single channels) matches your lamps

Usage recommendations

For reliable operation, use a dedicated, adequately rated DC power supply and place the controller where Wi‑Fi signal strength is strong. Configure scenes and schedules in the Shelly app to reduce manual operation, and consult the installation manual for safe wiring practices and compatibility details.
