Duplicated telegrams, probably missing acknowledge

[arnonym]

First of all: thank you for providing this add-on!

In the bus monitor in ETS I can see duplicated telegrams from devices that send data only to home-assistant (no other knx device is assigned to the group):

I'm using the TPUART from busware.

I wonder if these telegrams should be acknowledged by knxd? As you're also using the same USB dongle, do you also have that problem?

yes, I also see these yellow telegrams if you mean those. I don't get them for all group addresses though. Like my wind speed GA, which is also only connected/sent to HA does not have them. Others, do

These are retries because of a missing acknowledge. I would like to get rid of them to keep the bus traffic low. Is the wind-speed group address read by another knx device?

I could get rid of them by removing the "single" usb-filter. Not sure if there is any down-side to this, but everything seems to work as expected. Also my knx power supply stopped blinking the "bus error" LED.

Edit: it is NOT working as expected. The bus monitor stops randomly and the knx integrations also is not happy.

[da-anda]

no, windspeed and all other sensor values of my weather station are only read by HA, no other devices (HA is the only device in the GA, along with the sender).

The filter "single" should only apply to USB interfaces, not your Busware TPUART interface. edit: ah, hang on, I added the filters to TPUART as well, so yeah, you might have to remove it in the config

I had configured the interface in ETS manually with a faulty device address. Now using the auto-detected interface and the problem without using "single" is gone now. :see_no_evil:

The retries are only happening now when HA is reading all the states and the bus load is greater than 80%.

So all good now. Thanks for the help!
