Ikea Trafdri Light Bulbs Color Not Changing

[DonBennor]

Hi @foxthefox,

as mentioned in Issue #597, it is not possible to change the color of the Ikea Tradfri Light Bulb with the current productive version of the adapter. Switching the bulb on and off is possible, and the color temperature can also be changed, but not the color itself.

In the above-mentioned ticket, you already provided an analysis with the next steps required to fix the issue:

I compared the datapoints of this lamp with others. Indeed the color changeing is not possible, since the datapoints are differently named. hue -> unmapped_hue, saturation -> unmapped_saturation.
That needs some enhancements in the adapter as well as in the API-library to connect.

Versions:

Fritz Adapter: 2.5.11
JS-Controller version: 7.0.3
Node.js: v20.18.1
Operating system: docker (official image - v10.0.0)
FritzBox 7690: FRITZ!OS: 8.02

Thanks, most likely I will put this into 2.6.2 version.

You could try the version 2.6.2 if it is interacting with the Ikea lamp.
You need to be in expert mode and use the octacat icon.

Hi @foxthefox,
unfortunately it is not working. In the AVM Smart Home App you can choose for the light bulb between the mode "Weiß" or "Farbe".
If the app is in Mode "Farbe" and I switch manipulate the saturation or hue field in IoBroker Objects, than nothing happens.
If I am in "Weiß"-Mode in the App an change [Saturation] or [Hue], than the adapter crashes:

can you create the crash again and then go to "download log", then usually another window opens and there are some more lines in the debug in that area of error (some hint in which line it crashes). I would need that information.

Could it be the case that hue or saturation is set to 0 or null when going to White mode?

I have seen that most likely the needed variables are unsupported_hue/saturation. But these are not adjustable right now.
I have changed the code. You need to install the newer 2.6.2 and then stop adapter, delete the 2 datapoints in each lamp and restart adapter. Then these datapoints will be adjustable and hopefully will change something.

Hi @foxthefox ,
here is the log file but I think there is no new info. I switched to "log everything" in the Adapter menu.
Also deleting the two values an restarting wasn't bringing any benefits.

I can confirm that hue and saturation are going to "null" when switching to White Mode. See here the two screenshots:

White MODE:

version 2.6.2 is no on git and npm
it is maybe not solving the command problem, but it should at least prevent the break by an error

can you check the final 2.6.2?
