Built-in dimmer Shelly Pro Dimmer 0/1-10V PM — wireless, 110–240V, 3W standby, blue, 19×69×94 mm

Shelly Pro Dimmer 0/1-10V PM is a built-in wireless dimmer module for LED and lighting control that supports both 0–10V and 1–10V control interfaces. The device operates on 110–240 V AC, has low standby consumption, and connects via Wi‑Fi to enable remote brightness adjustment and integration with smart home platforms. Its compact form factor allows installation in-wall or behind switches and ceiling structures.

Advantages

The Shelly Pro Dimmer supports smooth dimming with 0–10V and 1–10V standards and provides real-time energy monitoring of voltage, current and power. It integrates with single- and double-key switches, can connect to the Shelly Plus Add-On for additional environmental sensors, and offers multiple communication protocols (KNXnet/IP, MQTT, REST/Webhooks) for wide compatibility with platforms such as Home Assistant, Google Home and Amazon Alexa. The device uses an ESP32 C3 CPU and 8 MB flash memory for reliable performance and future updates.

Suitable for

• Retrofit lighting control in residential or commercial installations
• Integration with smart home platforms and voice assistants
• Energy monitoring and load protection in lighting circuits
• Smooth dimming of LED drivers and 0–10V/1–10V compatible fixtures

How to use

Install the Shelly Pro Dimmer module into a wall console, behind a switch or inside a ceiling structure according to local electrical regulations. Connect mains (110–240 V) and wiring for the 0–10V/1–10V control interface and attach load and switches following the product wiring diagram. Use the Shelly app or your preferred smart home platform to connect the device to Wi‑Fi, configure dimming parameters, set schedules and enable energy monitoring. Optionally add the Shelly Plus Add-On for environmental sensing or integrate via MQTT/REST/Webhooks for advanced automation.

Recommendations

Ensure external overcurrent protection is installed (16 A, type B or C) and follow the recommended cable cross‑section (0.2–2.5 mm²) and wire stripping length (5–6 mm). Verify compatibility of connected LED drivers and 0–10V/1–10V fixtures before installation and keep the device within specified operating conditions (temperature, humidity, altitude).
