Does this module dim any bulb or lamp?

No. The module sends a 0-10V/1-10V signal to a driver, so the fixture or its LED driver must have a 0-10V input. Phase-cut dimmable lamps are not compatible.

What is the maximum relay load?

The relay switches up to 240V~ and 13 A. We recommend external protection of 16 A with a B or C characteristic.

Does it need a neutral wire for power?

No, the module does not require a neutral for its own supply, which simplifies installation in older boxes and boards in Moldova.

Which wireless protocols are supported?

Wi-Fi 802.11 b/g/n on the 2.4 GHz band and Bluetooth 4.2. There is no Zigbee, Matter or Thread.

What does the built-in meter measure?

Active and apparent power, active and apparent energy and power factor; voltmeter 110-240V and ammeter 50 mA-16 A, ±10 % accuracy.

Does it integrate with Home Assistant or Google Home?

Yes, via the Shelly app and local API it integrates with Home Assistant, Google Home and Alexa; it supports MQTT and scripts.

About this product

The Shelly Dimmer 0/1-10V PM Gen3 does not drive the lamp directly — it drives the lamp's driver: the module outputs a standard 0-10V analog signal (with 1-10V profile support) on the + and - terminals, while the power relay rated up to 240V~ / 13 A switches the luminaire supply. It is built for dimmable LED drivers, electronic ballasts and power supplies that are regulated over a 0-10V control line rather than by phase cutting. The controller operates as a current source delivering up to 35 mA. The built-in power meter (PM) tracks active and apparent power, energy and power factor; a 110-240V voltmeter and a 50 mA-16 A ammeter provide ±10 % accuracy. Two inputs, S1 and S2, accept push-buttons or switches for local control. Connectivity is Wi-Fi 2.4 GHz plus Bluetooth 4.2; no neutral is required to power the module. Scenes, schedules, scripting and MQTT are supported through the Shelly app.
