Shelly Dimmer 0/1–10 V PM Gen4 is a smart dimmer for devices using the 0–10 V and 1–10 V standard (LED lighting, motors, valves). It offers smooth dimming, power consumption monitoring, and convenient control via an app as well as a traditional wall switch. With support for Wi‑Fi, Zigbee, Bluetooth, and Matter, it’s easy to integrate into a modern smart home, and by installing it behind an existing switch you can keep your interior’s original look.
Compact module for installation behind a switch
The compact design makes installation in a wall box easier – you get smart control without replacing existing switches and without changing the room’s design.
Precise 0–10 V / 1–10 V control and easy wiring
Clear terminals and a wiring diagram help during installation. The dimmer is intended for devices with a 0–10 V / 1–10 V control input and also supports S1/S2 inputs for push-button control.
Reliable terminals for safe wire connection
The robust terminal block enables firm and tidy wire connections, contributing to safe operation and stable contact in the installation.
Shelly Dimmer 0/1–10 V PM Gen4 is a universal solution for upgrading control of lighting and other devices with a 0/1–10 V input. Installation in a wall box (e.g., behind a switch or in a ceiling structure) lets you keep existing control while adding smart automation features.
The device gives you precise control over the room’s ambiance – set minimum and maximum brightness, transition speed, and the brightness level after switching on. A practical night mode automatically dims the light during selected hours, making it suitable for a bedroom, children’s room, or hallway.
Connecting to the smart home ecosystem is easy thanks to multi-protocol communication and broad compatibility. The dimmer supports scenes and automations (timers, sunrise/sunset, scripts) and continuously measures voltage, current, and the power consumption of the connected load for better insight and cost optimization.
