Shelly Pro Dimmer 1PM is a single-channel DIN-rail smart dimmer with integrated power monitoring for compatible dimmable lighting. Shelly specifies support for a range of halogen lamps, dimmable LED lighting and ferromagnetic transformers on 110–240 V AC supplies.
Automatic dimming calibration is designed to provide smooth control across the usable brightness range, while switch or push-button input modes retain familiar physical control. Ethernet, Wi-Fi and Bluetooth connectivity, local web access, schedules, scenes and Shelly automation features make it suitable for centrally managed residential and professional lighting circuits.
