Shelly Dimmer 0/1-10V PM Gen4 (Zigbee, Matter, Wi-Fi)

Product detailed description

Smart Shelly Gen4 0-10V dimmer with power metering and Matter and Zigbee support 

Shelly Dimmer 0/1-10V PM Gen4 is a compact smart 0-10V dimmer that controls dimmable LED drivers with a 0-10 V or 1-10 V input. You install it in a wall box behind your existing switch or in a ceiling, turning ordinary LED lighting into a fully smart light: dim it with the wall button, in the app, by voice or automatically by time of day, sunrise and sunset.

Compared with the previous generation, the fourth generation adds Wi-Fi 6, Zigbee and Matter in a single module. The built-in relay output with power metering fully cuts power to the LED driver when switched off and shows you how much energy your lighting really uses.

The principle is simple: the module does not dim the mains voltage like a classic dimmer, it sends the LED driver a 0 to 10 V control signal. The driver then smoothly adjusts the brightness without flicker or buzzing. That makes this 0-10V lighting controller ideal for LED panels, linear luminaires, LED strips with a 0-10V driver and professional lighting in offices, shops and restaurants. The signal can also control other devices with a 0-10V input, such as valves or motors.

Everyday control stays the way you know it. Connect one or two existing push buttons to inputs S1 and S2: with one button, a short press switches and a long press dims; with two buttons, one raises and the other lowers the brightness. In the Shelly Smart Control app you set the minimum and maximum brightness, fade rate and transition time, so the light comes on exactly as gently as you want.

Thanks to the ESP32-C6 chip and 8 MB of memory, this Wi-Fi dimmer handles advanced features without the cloud: 20 schedules, night mode with reduced brightness, auto on and off, scripts, webhooks, MQTT and KNXnet/IP. Automations run locally in the module, so they keep working even when the internet goes down.

Compatibility is key in a smart home. Out of the box the module runs in Matter mode, so you can add it to Apple Home, Google Home, Amazon Alexa and SmartThings without an extra hub. If you build on a Zigbee network, switch it to Zigbee 3.0 mode and it will also act as a repeater that extends the range of your other Shelly Zigbee devices. This smart dimmer also works as a Bluetooth gateway for Shelly BLU sensors and as a Wi-Fi range extender.

The manufacturer model code is S4DM-0010WW, also listed as S4DM0010WW.

Who is the Shelly Dimmer 0/1-10V PM Gen4 for

• Home and apartment owners with LED lighting on a 0-10 V or 1-10 V driver who want dimming from their phone without replacing fixtures.
• Electricians and integrators retrofitting lighting in offices, shops, hotels or schools.
• Apple Home, Google Home and Alexa users who want simple setup via Matter.
• Home Assistant and Zigbee enthusiasts who value a local API, MQTT and scripting.

Use cases

• Dimming LED panels in the office: brightness rises automatically in the morning and the lights switch off after working hours.
• Ambience in a restaurant, café or bar: in the evening, dim the lights to a pleasant level with one button or on a schedule.
• Night mode in the hallway and kids' room: after dark the light comes on at low brightness only, without glare. 🌙
• Smart control of an LED strip with a 0-10V driver in the living room, kitchen or ceiling.
• Retrofitting existing lighting: keep your original switches and wiring and just add the module behind the switch.
• Monitoring lighting energy use in real time and cutting energy costs.
• Controlling valves or motors with a 0-10V input as part of your home automation.

Key features

• Multi-protocol: Wi-Fi 6, Bluetooth 5.0, Zigbee 3.0 and Matter in one module.
• Power metering: voltage, current and load power with ±10 % accuracy.
• Relay output up to 13 A: fully disconnects the LED driver when switched off.
• Control with existing switches: one or two push buttons on inputs S1 and S2.
• Adjustable dimming: minimum and maximum brightness, fade rate and transition time.
• Local automations: 20 schedules, night mode, timers, scripts, webhooks and MQTT.
• Repeater and gateway: Zigbee repeater, Wi-Fi range extender and Bluetooth gateway for Shelly BLU.
• Protection: against overheating, overvoltage, overcurrent and overload, with an internal temperature sensor.
• No hub or subscription required: works locally and via the cloud, and the Shelly Smart Control app is free.

Technical specifications

Protocols and compatibility

• Matter (default mode): Matter over Wi-Fi works right out of the box: add it to Apple Home, Google Home, Amazon Alexa or SmartThings. Your ecosystem needs its own Matter controller (e.g. Apple TV/HomePod, Google Nest Hub).
• Zigbee 3.0: after switching the profile (press the button on the module 5 times) it pairs with a Zigbee coordinator or gateway, for example from our Zigbee control units category. Matter and Zigbee always run one at a time. Check support in Zigbee2MQTT or ZHA for your version before buying.
• Wi-Fi 6 (802.11 b/g/n/ax, 2.4 GHz): local and cloud control via the Shelly Smart Control app and web interface, no hub needed.
• Bluetooth 5.0: quick initial setup from your phone and a gateway for Shelly BLU sensors and buttons.
• Home Assistant: native Shelly integration with local communication over Wi-Fi, or via Matter or Zigbee.
• Amazon Alexa, Google Home, SmartThings: also via the Shelly cloud link if you don't want to use Matter.
• Local API: HTTP (RPC), MQTT, webhooks, UDP and KNXnet/IP for integration into building automation.

Why choose the Shelly Dimmer 0/1-10V PM Gen4

• One small module turns ordinary 0-10V LED lighting into a smart light that works with every major ecosystem.
• Power metering and a relay that fully disconnects the LED driver save energy even in standby.
• Automations run locally, so the light responds even without internet.

Compared with its predecessor, the Shelly Dimmer 0/1-10V PM Gen3, you also get Zigbee 3.0, Wi-Fi 6 and Matter straight from the factory. If your fixtures have no 0-10V input (dimmable bulbs and 230V LEDs), choose the classic phase-cut dimmer Shelly Dimmer Gen4.
