Lighting controller Shelly PM Gen3 WiFi Bluetooth 0/1-10V for dimming and power monitoring

The Shelly Dimmer 0/1-10V PM Gen3 is a compact lighting controller that supports 0/1–10V dimming and integrated power monitoring. It connects via Wi‑Fi and Bluetooth and is compatible with common automation platforms, allowing brightness control and measurement of voltage, current and power without requiring additional hubs. The device is intended for installation in wall boxes, behind switches or inside ceiling structures and is suitable for residential and commercial lighting systems.

Advantages

The controller combines dimming and energy measurement in a single unit, supporting one-way and two-way dimming modes, night mode scheduling and precise monitoring of voltage (V), amperage (A) and power (W). It includes an ESP32 C3 processor, 8 MB flash memory, Wi‑Fi range extender and BLE gateway functionality for improved connectivity. Protocol support includes KNXnet/IP and MQTT, and the unit integrates with Alexa, Google Assistant and Home Assistant. The compact housing and standardized wiring options simplify installation.

Suitable for (tasks / use cases)

• Centralized dimming of LED and other compatible luminaires using 0/1–10V control
• Monitoring energy consumption and power parameters in lighting circuits
• Integration into smart home or building automation via MQTT, KNXnet/IP or common voice assistants
• Installing behind wall switches, in junction boxes or ceiling cavities

How to use

Install the Shelly Dimmer Gen3 into a suitable mounting location (wall box, behind a switch or in a ceiling cavity) following local electrical safety rules and using the recommended wire cross-sections (0.2–2.5 mm²) with 5–6 mm stripped length. Connect supply voltage (110–240 V~) and the 0/1–10V control lines according to the wiring diagram. Configure Wi‑Fi or Bluetooth connection via the Shelly app or a compatible automation platform, set dimming mode (one-way or two-way) and program schedules, night mode and measurement settings as required.

Usage recommendations

Use within the specified environmental limits (-20 °C to 40 °C, 30%–70% RH) and avoid installation above 2000 m. Ensure screw terminal tightening torque does not exceed 0.4 Nm and follow recommended wire cross-sections. Verify compatibility of connected luminaires with 0/1–10V current‑source control. For integration with KNXnet/IP or MQTT systems, update firmware and follow platform-specific configuration guides.
