Could not sync group address... L_DATA_CON Data Link Layer Confirmation timed out for <TunnelingRequest...>

Have done that - here is the log output filtered over one of the GAs:

2023-12-27 08:51:35.594 WARNING (MainThread) [xknx.log] Can not process <Telegram direction="Incoming" source_address="1.1.31" destination_address="3/3/48" payload="<GroupValueResponse value="<DPTArray value="[0xd]" />" />" /> for G241 Kitchen Yard - Value: <CouldNotParseTelegram description="Invalid payload length for DPTPower" expected_length="4" payload="<DPTArray value="[0xd]" />"/>

2023-12-27 08:51:45.337 WARNING (MainThread) [xknx.log] Could not sync group address '3/1/46' (G241 Kitchen Yard - Brightness)

Screenshot from ETS Diagnostics filtered over the same address:

There are a lot of Read->Response logs in ETS Diagnostics, however, a number of them look like the G241 one - 2x Read Request and only 1x response.

Really weird?

My bad - it seems one of them is missing.

So the STATUS is a binary KNX flag which shows if the light is on/off. The DIMVAL is for the value of the dim ie 0…100%. obviously 0% is off.

MDT KNX actuators work like that, and in HA they are set up correctly:

- name: "G241 Kitchen Yard"
        address: "3/1/42"
        state_address: "3/1/45"
        brightness_address: "3/1/44"
        brightness_state_address: "3/1/46"

You are mixing up error messages.
Error: KNX bus did not respond in time is completely different from
Can not process... Invalid payload length for DPTPower. Latter is a configuration issue - wrong GA (invalid DPT) for some config key.

I think I copied and pasted incorrect from log…

I was out for a few hours and just refreshed the log without starting HA:

Here are the detaild logs on the same GA as used before.

The power issue will investigate - looks like a mix up of length…sorry about that.

Have fixed the other issue…

@farmio

Hi Matthias,

I can only apologise - I have figured out those issues. They seemed random, but were not.

All of them were incorrect settings on my account - I unfortunately did all of the KNX integration by hand instead of exporting GA into Excel and making sure I had no typos.

Sorry about wasting your time, and thanks for pointing me in the right direction.

Anyone else ever having this issue where you can’t see the trees in front of the forest: Best is to test in diagnostics if the GA returns the response, do them one by one and then triple check the HA KNX integration. I simply had typos in there…

Thanks
Martin
