Shelly Dimmer 0/1-10V PM Gen4 – Dimmer relay module with energy monitoring, Wi-Fi, Zigbee (S4DM-0010WW)

The Shelly Dimmer 0/1-10V PM Gen4 is a professional smart dimmer controller designed for controlling 0–10V and 1–10V dimmable power supplies and other compatible devices. It is an ideal solution for modern LED lighting systems, dimmable drivers, or valve control in both residential and commercial environments.

One of the biggest advantages of the Gen4 series is its multiprotocol operation, supporting Wi-Fi, Bluetooth, Zigbee, and Matter, ensuring exceptionally broad compatibility with various smart home systems. The device can operate independently on a local network while also integrating seamlessly into cloud platforms and open-source systems such as Home Assistant.

The Shelly Dimmer 0/1-10V PM Gen4 is especially suitable for applications where precise brightness control and ambient lighting are essential. It provides a professional-grade solution for restaurants, bars, offices, cinemas, and premium residential lighting systems. Smooth transitions, configurable minimum and maximum brightness levels, and intelligent scheduling allow the creation of the perfect lighting atmosphere.

The device includes built-in power monitoring, enabling real-time tracking of connected lighting energy consumption. Advanced Shelly automation features such as scripting, MQTT, Webhooks, and KNXnet/IP support make it suitable for integration into complex building automation systems.

Existing lighting installations can be modernized easily, as the device supports traditional wall switches and push buttons. In addition to single-button and dual-button dimming control, it supports smooth dimming transitions, night mode, and sunrise/sunset-based automations.
