Error turning light on

[JohnnyFlash]

I am having an issue with a light converted from custom_white with the jnimmo version of the integration. I recently upgraded HA to 3.9.2 and of course custom_white was broken. I followed recommendations to switch to this version of the integration and it went mostly smoothly.

I converted custom_white entities to color_temp

          - channel: 131
            name: Maker Light 1
            type: color_temp
            channel_setup: dt

However, now when I attempt to turn on the light I get the following error - failed to call service light/turn_on

My RGB light bars still work correctly as type: rgb

Can you show me under the attributes what the value is of 'Dmx values'? This config does seem to be correct.

Think it might be related to the migration process itself; try completely removing the integration and re-adding it once again?

To find the root cause, it would help me a bit if you could include the bit from the logs around this error.

I published a quick v0.0.5 that will prevent crashing the flow and instead will print a warning message. It doesn't fix the root cause, but at least it will reduce the severity of the error.

After updating, could you please find this log line for me?

log.warning(f"Value for channel {channel} isn't within bound: {value}")

[JohnnyFlash]

Lights are working-ish.

I have noticed that the control bars seem skewed. For instance 0% brightness is around the middle of the the brightness bar.

Here's the data you were looking for. [custom_components.artnet_led.light] Value for channel t isn't within bound: -45.82949308755758

[Breina]

Ah I see, that explains it. The brightness is set by HA itself, I'm not even touching that. I think that the color temperature value coming from HA is also offset similarly. It's giving you values that are outside of its own specification.

It might have to do with the data model of ATTR_WHITE_VALUE being interpreted as a ATTR_COLOR_TEMP. I know it's annoying, but I think perhaps it's best if you do a clean install:

1. Remove, or comment out, the config of the faulty lights
2. Restart HA
3. Remove the entities of the faulty lights
4. Put back the config
5. Restart HA

@JohnnyFlash Did that latest procedure fix it for you?
