Shelly Pro Dimmer 2 is a dual-channel smart DIN-rail dimmer for convenient lighting control at home and in the office. It offers smooth dimming with automatic calibration, local and remote control without a hub, and connectivity via Wi‑Fi, Ethernet, and Bluetooth, including integration with Alexa, Google Home, and SmartThings.
Two channels and smooth dimming with automatic calibration
Control two lighting circuits independently and enjoy smooth dimming thanks to automatic calibration. Set the transition time and the dimming speed to match your preferences.
Wi‑Fi, LAN (Ethernet) and Bluetooth, and hub-free control
The device works without an additional gateway (hub)—you can control it locally over Wi‑Fi or remotely. It supports Wi‑Fi, Ethernet, and Bluetooth for flexible installation and a stable connection.
Safe DIN-rail installation and protections for reliable operation
The practical design for DIN-rail mounting makes installation in a distribution board easier. Protections against overheating, overvoltage, overload, and excessive power consumption help protect both the device and the connected load.
Create the perfect atmosphere in any room exactly as needed. Shelly Pro Dimmer 2 enables precise brightness control in two independent channels, and thanks to the built-in web interface, you can monitor device status and control it from anywhere (within the local network or via cloud services).
The dimmer supports various wall-control methods—push buttons and switches—and offers features you will appreciate in everyday use:
- Automatic dimming calibration for stable, smooth operation across the full range
- Night mode—brightness level setting after dark
- Adjustable transition time (0–100%) and brightness change speed when holding a button
- Schedules, timers, and scenes—weekly schedules and smart-home automation
For safe operation, the device is equipped with protections against overheating, overvoltage, overload, and excessive power consumption. It is suitable for a wide range of light sources up to 200 W, including LED bulbs, incandescent and halogen bulbs, and transformers for low-voltage lighting.
