Shelly Pro Dimmer 2PM is a two-channel DIN-rail smart dimmer with integrated power metering for professional lighting installations. It allows two compatible dimmable lighting circuits to be controlled independently while reporting their energy use and retaining physical wall-switch or push-button operation.
Ethernet, Wi-Fi and Bluetooth provide flexible network connectivity, while automatic dimming calibration, adjustable minimum and maximum brightness, night mode and configurable fade behaviour support practical lighting control. Scripting, webhooks, MQTT, secure local interfaces and KNXnet/IP are also supported.
