Hello, I encountered some issues while using homeassisant regarding my DALI dual color temperature bulb. #1558

Description of problem:

"Hello, I have encountered some issues while using Home Assistant with my DALl dual color temperature bulb. The problem lies in the connection between my dual color temperature light bulb and Apple Home through Home Assistant. I am controlling it to switch scenes via Apple Home, which involves simultaneous control of both brightness and color temperature. However, I have noticed that it does not function as expected, occasionally getting stuck in either the color temperature or brightness settings. Interestingly, when I used Node-RED to control the scene switching with a dual color temperature light bulb, everything worked normally. This leads me to believe that there might be an issue with the order in which instructions are sent in ETS." Snipaste_2024-08-29_11-36-53_1

Hi 👋! Unfortunately, from your screenshots, I can't tell what you mean by "an issue with the order in which instructions are sent in ETS". Is this using a HA scene containing multiple light entities?

It looks like first brightness, then color temperature values are sent to the bus - for multiple devices consecutively. Which seems fine to me. There doesn't seem to be any status update telegrams from the DALI device though - that would maybe help identify the issue.

yes,i using a HA scene containing multiple light entities If I use HA scenes to control multiple light entities, it will be sent in the form of the top on the picture , which will cause the scene of brightness or temperature color to be different. for example, I set the brightness of 100, maybe this light is interrupted at 20 brightness, but when I use nodered manual, i delay the brightness of all lights and adjust the color temperature. Therefore The state will be changed according to our scene Therefore, when the lighting entity is controlled through HA, can you first send the brightness value of all light entities and then send the color temperature value of all light entities, which will not cause the actual light brightness and scene settings of the scene settings inconsistencies.

No, we can't do that. From a HA integration point of view, a call to a group of entities isn't distinguishable from multiple single calls (maybe manual etc.). So we don't know about the group / HA scene.

Tbh, to me this sounds like an issue of the DALI actuator. Imho it should be able to process multiple telegrams like that - maybe there is some configuration to set.

Thank you very much for your help in trying to replace dali gateway
