Shelly Dimmer2 (EOL)

Shelly Dimmer Gen3 is a smart, single-channel dimmer module designed for seamless control of lighting with both Wi-Fi and Bluetooth connectivity. It allows dimming with or without a neutral wire (a bypass is required for loads under 20 W), and offers advanced features like energy monitoring, scripting, and local/remote control.

Features

• Supports dimmable LED lamps (up to 150 W), incandescent/halogen bulbs (up to 200 W), and low-voltage lighting via transformers
• Works without neutral wire (bypass recommended for loads under 20 W)
• Dual wireless connectivity: Wi-Fi (802.11 b/g/n) and Bluetooth BLE
• Functions as a Wi-Fi extender and BLE gateway
• Embedded web interface, scripting, customizable schedules, Webhooks, and MQTT support
• Safety protections including overvoltage, overcurrent, overheating, and overpower (when neutral is present)

Main Applications

• Retrofit or new installations—fits behind wall switches or in tight electrical spaces
• Scene automation (e.g., dimming for movie nights, night lighting)
• Local smart automation even in the absence of internet connectivity
• Extending Wi-Fi coverage and integrating BLE sensors

Compatibility

• Compatible with Shelly Smart Control app, Alexa, Google Home, Home Assistant, and MQTT platforms
