Gledopto ct colormode stopped working

[Jolle666]

Hi,

Since deCONZ v2.05.76 ct colormode stopped working with my Gledopto lights (GL-C-006 and GL-C-008). API error in Node-RED/Home Assistant. 2.05.75 is fine.

Maybe it's related to #2798?

Thanks!

Update to .77, there's a fix for ct as I recall

[ebaauw]

Only for IKEA. What type of GLEDOPTOs are these? Could you list the resources and screenshots of the Color Control cluster (after reading the attributes)?

[Jolle666]

The Gledopto GL-C-006 is the WW/CW LED controller (firmware 1.0.6). The GL-C-008 is the RGB+CCT LED controller (firmware 2.0.0).

I run Home Assistant with the Phoscon app on a RPI4 with Conbee II. I'm sorry, but not sure where to find resources and Color Control cluster.

Hm, both should expose state.ct and work?! Did you happen to try .77?

What API error do you see? Can you find out what API requests are sent?

[ebaauw]

Double-checked the GL-C-008: it's working in 2.05.77:

@ebaauw thank you so much.

Just testet once more. This is the JSON in Node-RED:

With 2.05.75 the LED controller is working and with no error in Node-RED:

With 2.05.77 the LED controller is not working and I get this API error in Node-RED:

with this debug message:

This is the info in the Phoscon app:

[ebaauw]

Ah OK: you cannot set colormode: it's a read-only attribute. It's set automatically when you set the colour (temperature) trough xy, hue and sat (hs), or ct.

It has never worked, but was silently ignored. I fixed the handling of errors for a PUT of the light state, so you're only seeing the error since v2.05.76.

@ebaauw Ah, now it all makes sense and is working perfect. Thank you so much!
