SHELLY Dimmer Gen4 Wi-Fi + Bluetooth smart dimmer/dimmer relay module green S4DM-0A101WWL

The Shelly Dimmer Gen4 is a smart, flush-mounted light dimmer that fits behind a standard wall switch. It uses phase-cut dimming, so it works with LED lamps, incandescent bulbs, halogen lights, and both electronic and conventional transformers.

The module supports a wide range of smart home protocols, including Bluetooth LE, Zigbee, Matter and Wi-Fi, and works with Apple Home, Google Home, Amazon Alexa and Samsung SmartThings. Support for KNXnet/IP, MQTT and Webhooks allows integration into professional building automation systems. It can also operate without a neutral wire.

At 43.5 × 38.5 × 17 mm and 24 g, the compact unit is designed for indoor use at 20 to 40 °C and 30 to 70 % relative humidity. Wiring is made with screw terminals accepting cables from 0.2 to 2.5 mm².
