Hombli smart bulb only works in color mode

[PrimaveraNL]

Added a hombli smart bulb to my home.
It appears in homekit only as color bulb. In the Tuya Smart app, it has more options amongst which the option for different white colors.

Did you mean this bulb should be able to set color temperature, but can't be set in the HomeKit?

[PrimaveraNL]

Yes. In the Tuya app it has 4 panels, "white" for white color and brightness, "color" for color setting and brightness, "Scene" and "Music" of which the latter two probably are not supported by homekit.

Could you please provide some device info? Enable the homebridge in debug mode, and upload some logs of the device functions, status, product_id.

[PrimaveraNL]

How do I set the homebridge to debug? I do know where to find debugging options in the tuya iot platform but not in the homebridge itself?

[0x5e]

If you start Homebridge with Web GUI, it can be found in Setting page. If started by cli, just add -D option. For example: homebridge -D

So here are the properties and instruction set. See the 'white' mode, this is what I'm missing in homebridge currently for this device.

The lightbulb is complicated, it has C, CW, RGB, RGBC, RGBCW 5 types. Some RGB light don't have white mode. Let me figure out how to handle this.

[PrimaveraNL]

Great.
Let me know if I can help with additional data?

[0x5e]

That's enough, just I don't know how to handle 5 types of light with 1 code.

#12 should fix this. Please try 1.6.0-beta.12

I pulled it and tried. I don't see any difference in homekit app. Should I remove the accessory and add it again or should it function on basis of the old install?

No need to remove, just upgrade to the beta version. Can you record a video about the issue？Maybe I didn't fully understand the text, or maybe your operation is not correct

The Tuya app shows 4 tabs, of which the first two are White and Color
White tab:

Color tab:

The Apple homekit app. through the Tuya bridge, only shows this panel:

... which is the same as it was before the update. So I don't see anything different after the update.

I removed the device from the app and added it because the status log says it was 'loaded from cache' and I wanted to make sure older settings would not conflict.

In the Home App, double click one of the six panel, then you can see the color setting or color temperature setting, switch to temperature panel and pick one temperature, then save. That's how it works.

[PrimaveraNL]

Allright then.
That doesn't really solve my problem, as the bulb remains in color mode that way. It seems to operate differently in color and white mode, which can also be seen in the instruction set. It never gets into white mode like this, which it does through the Tuya app.

Thank you for your effort trying to solve this; I guess this bulb is just not compatible enough.

Okay, one last try, can you open the homebridge debug mode and upload the full log during your lightbulb operation？

[PrimaveraNL]

Here it is.
I already was on debug mode for another issue, so there could be some other movements of "Eettafel dimmer" in it which are unrelated.

I opened the homekit app, switched the Hombli bulb to 'ON', then double-clicked one of the six colored dots and went to 'temperature' option. Changed the temperature a bit and then copied the log which is below.

If it helps in any way, and there is a way, I could capture the log or instruction that is sent from the tuya app when I control it from there?

I know where the problem is. I will submit a new version.

Please try 1.6.0-beta.13

[PrimaveraNL]

Pulled this and this works better than before. Thank you.
