KNX-HA climate, MDT BE-GT2Tx.01 with MDT AKH-0600.02

Hello everyone,

I’m a newbie and have already managed to do a few things. But I’m somehow getting desperate with this topic. I’m already feeling dizzy from all the reading and trying.
I keep getting this error message in the HA:

024-12-30 18:44:30.630 WARNING (MainThread) [xknx.ga_dpt] DPT decoding error. Telegram from 1.1.253 to 9/3/2 with payload <DPTArray value=“[0x0,0x32]” /> can't be decoded by DPTValue1Count: <CouldNotParseTelegram description=“Invalid payload length for DPTValue1Count” expected_length=“1” payload=“<DPTArray value=”[0x0,0x32]“ />”/>

This message appears regardless of whether I adjust the setpoint on the glass button or in the HA. If I read the address 9/3/2 in the group monitor, the same error message appears. But everything works.
I have hidden the operating mode for the time being to find out.

> setpoint_shift_mode: “DPT9002”
> # operation_modes: ['BUILDING_PROTECTION', 'COMFORT', 'ECONOMY', 'STANDBY']
> # command_value_state_address: “2/1/2

I have added the group monitor from HA, but there are no values

Can someone please help me ?
Greetings
Klaus

Hi !

Well, then just leave it as is

For the log warning see KNX RGBW State address DPT confusion - #2 by farmio

Having both doesn’t really do anything. Use either direct target temp setting, or setpoint_shift.

PS: see How to help us help you - or How to ask a good question §11 for how to format yaml code here.

Hi,
I have now only activated a few lines (red).
If I now increase or decrease the temperature on the switch, I get the error message again. If I change the temperature in the HA, no error message appears.
If I do not activate the line with #, no error message should be created, right?

Regards
Klaus

Have you read the link above? This log message has nothing to do with any entity behaviour or yaml configuration. It points to a wrong DPT setting in your ETS project.

Yes, I think it comes from the KNX bus

Also, if your actuator works with setpoint shift, configure it accordingly, but omit target_temperature_address:.
You can either change the base target or the setpoint-shift value, not both.

This is what the log file says:

Exactly the same as above

Hi,
I have now tried a few things again, but the message still appears.
Enclosed are instructions from MDT (unfortunately only in German).
The DPT is also set correctly.
I am really at a loss…

I am quite serious about this:

No matter what you do with your YAML, [xknx.ga_dpt] log messages are 100% not related.
Just ignore them or fix and re-upload your ETS project.

Hi,

What can I say, after I deleted the ESTS file and reloaded it, I no longer get an error message.
Unbelievable…
