KNX Light: xyY Issues

Configuration
1

I have some RGB+CCT LED Strips that I try to control using a DALI DT-8 Controller behind a Theben DALI-Gateway P64 KNX

I tried two different DALI Controllers:

Both work fine in RGBW mode but they fail in xyY mode.

Can anyone confirm that the xyY Mode is still working as expected?

Hi :wave:!
Do you have a more precise failure description that “they fail”?
Maybe add ETS Group monitor logs and group object associations.

Also: does it work from other devices (or ETS)?

I have the group monitor logs and a video of which shows the response. The camera I used was pretty slow to update, therefore there are some delays.

I have no other device on the KNX bus that is able to control a light using xy mode as my MDT Glass Push Button keypads only support HSV.

The Dali Gateway is actually manufactured by IPAS GmbH in Germany and according to my latest support request with Theben I got a response from them that there were some Firmware issues in early models, unfortunately there are no firmware updates available from Theben so far. Waiting for response to my follow up email.

You can send xyy colors from ETS group monitor for tests.
In this video it looks like every color is rendered blue.
The sent values and the received status messages seem to match - except for brightness, where it is reported 0 in the status :thinking: (in the request it’s set invalid because it should only change color).

5

Will try to send some xyy colours using ETS, is there a cheat sheet somewhere to set the xy values?
Might not be today though but will report back

6

No idea, sorry.

Did some testing with ETS to send some xy values to the gateway. Looks like the Gateway has an issue and hopefully I will get a new firmware soon.

IPAS did test their version of the gateway with the MiBoxer Dali DT8 driver and this was working.
Seems that the Theben version did not get the latest firmware.
