• I have checked the troubleshooting section and my problem is not described there.
• I have read the changelog and my problem is not mentioned there.

Deploy method

Manually built (git clone - npm run build - npm install

Z-Wave JS UI version

9.18.1

ZwaveJS version

13.3.0

Describe the bug

Light objects are advertised for MQTT AutoDiscovery using an out-of-date method.

The documentation at https://developers.home-assistant.io/docs/core/entity/light/ says that all lights should report supported_color_modes, including those which only support ColorMode.BRIGHTNESS or ColorMode.ONOFF.

To Reproduce

Use a Z-Wave light/dimmer device, and see the contents of its discovery topic.

Expected behavior

I expected to see

  supported_color_modes: ["brightness"],

or

  supported_color_modes: ["onoff"],

in the device configuration object.

Additional context

No response
