QLC+ can send lighting values to DMXSmartLink over Art-Net. DMXSmartLink then controls compatible smart lights through their configured integration. The two applications must agree on the destination, universe and complete channel layout.
1. Prove direct control
Install a supported DMXSmartLink version and add your Govee lights through the available integration. Test brightness, colors and white temperature directly before adding QLC+. If this fails, changing the QLC+ patch will not fix the underlying device connection.
2. Configure Art-Net output in QLC+
Use the QLC+ Art-Net plugin documentation for your installed version. Select the correct network interface and enable output for the intended universe. When configuring a unicast destination, target the DMXSmartLink host, not an unrelated local address. Ensure host firewalls and network isolation permit the intended traffic.
3. Match the patch
Create or select a QLC+ fixture definition matching the channels DMXSmartLink exposes for that device or group. Match the start address and check universe numbering. Do not assume a three-channel RGB definition is sufficient if the mapping includes dimmer, power or white-temperature controls.
4. Test one channel at a time
Send modest brightness, then primary colors and off. Verify the receiving channel values and the physical light. If the wrong control moves, compare the channel footprint and mode before changing network settings. Save the working configurations in both applications.
Pixel control is a separate requirement
The previous guide described fixed Govee segment counts, an assumed segmented-color API and a per-pixel patch workflow without establishing support. Do not use those assumptions. Addressable hardware alone is insufficient: the integration and DMXSmartLink must expose a supported segment mapping. Start with whole-device controls and verify any more advanced capability against the exact release and model.
Check your version and your lights
DMXSmartLink runs on supported macOS, Windows 11, Ubuntu and Raspberry Pi 5 systems, or on a preconfigured HUB. It accepts Art-Net and sACN input and provides Art-Net output; physical DMX requires a supported interface. Smart-light functions depend on the model and integration, including Homebridge or Home Assistant. The bundled Home Assistant companion on Pi/Ubuntu is experimental. Cloud integrations require internet; local paths have their own compatibility requirements.
