KNX warnings

Hi,

I am having the following warnings in my logs:

This has been like this for about a week, and happens only when HA is restarted.

The circadian integration has been working great for the last couple of months, and I just installed HACS today, so would tend to disregard them as the root of the problem…

It woukd be nice if someone can help me to solve the problem.

Thanks!

The Knx integration tries to read the sensor values on startup and once an hour - it sends a GroupValueRead request to the bus. These errors indicate that there was no answer.

You can try to make your sensor values readable (L-Flag, Filtertables of line couplers) or disable the synchronization by adding sync_state = False to your sensors.

Or you just ignore these errors - incoming telegrams should be handled anyway.

Hi thanks for your answer. The warnings are gone, looks like I forgot to properly configure or program some new sensors…
