KNX integration stops working after some minutes #39298

LavermanJJ · 2020-08-26T19:57:11Z

The problem

When starting with HA, setup went fine. Different KNX entities can be controlled and status is updated when changes come from KNX. However, after some time (< 15-20 min), the two log messages below occur and the integration is broken: Changing the state in HA has no effect on KNX and vice versa.

Environment

Home Assistant Core release with the issue: 0.114.3
Last working Home Assistant Core release (if known): -
Operating environment (OS/Container/Supervised/Core): HassOS 4.12 (RPi3)
Integration causing this issue: KNX

Additional information

Searching the web it seems that receiving unknown telegrams caused the integration to break (KNX hub craches: APCI not supported #32394). However, the issue is closed, and this is just a warning, so it may be unrelated?!
I have a working OpenHAB setup that integrates with my KNX running in parallel. Changing something there got reflected in HA and vice versa but only until HA KNX crashes. OpenHAB continues to work.

The text was updated successfully, but these errors were encountered:

Hey there @Julius2342, @farmio, @marvin-w, mind taking a look at this issue as its been labeled with an integration (knx) you are listed as a codeowner for? Thanks!

farmio · 2020-08-27T07:00:48Z

Hi! 👋
This is a bug that was introduced to routing connections with the fix for tunneling connections you mentioned above. 😬
It should be resolved with xknx 0.12.0 coming with HA 0.115.
Please let us know if the issue persists then.

As a workaround you could use a tunneling connection until then.

Could you maybe try to stop OpenHAB for a test to see if the telegrams are sent from this? I'd be interested in the source. I've only seen such telegrams from ETS searching for devices in programming mode or doing a Line-Scan.

LavermanJJ · 2020-08-27T18:14:18Z

Hi - thanks for your fast reply! It seems to hold true, what they say about the HA community 👍
Thanks for the heads up for the fix in HA 0.115. Did I understand this correctly, that HA releases are published ~1 / month?

I tried with tunneling, but that also fails with the same error after some minutes. So I'll probably have to test taking OpenHAB offline.

farmio · 2020-08-27T18:28:58Z

There is a calendar here: https://developers.home-assistant.io - I think it is 3 Weeks.
If you're a little adventurous you can already test 0.115 if you run the dev branch. Any feedback for this issue would be welcome. Or wait for the beta and try it 1 week earlier.

LavermanJJ · 2020-08-27T19:04:10Z

Sure, here are the error messages, when tunneling is used.

In addition, I set OpenHAB offline for some minutes (no extensive testing), but during that time no error occurred. Seems like you're right on this one.

cyberjunky · 2020-08-27T19:36:13Z

I will do some testing tomorrow as well. Thank all for the effort and work on the KNX integration. Maybe there are more KNX HA users than everyone thinks ;P Op do 27 aug. 2020 20:29 schreef Matthias Alphart <notifications@github.com

@LavermanJJ you seem to be still routing

LavermanJJ · 2020-09-03T21:05:56Z

Sorry for the delay. Been off for some days. You were right, tunneling works 👍
Do you want me to close the issue, or keep it open for now, and close it with the next release?

marvin-w · 2020-09-03T22:49:20Z

Feel free to close it right away.
