KNX (new) entities from knx.yaml are not visible/accessable in the HA | Home Assistant | Page 1

Hi,
I'm using KNX with a separate knx.yaml instead of the graphical Entities-Manager from the KNX integration.

I have a lot of lights, switches, covers and climate entities in my system.
Everything a created some month ago show up eventually in the system (dashboard, etc) and I can use it.
Everything I'm now adding to my yaml files will never show up.

I checked the config-files, I reloaded the config files, I restarted to complete HA.
Also Developer-Tools/States does not show the new entities.

Is there a way to debug the knx.yaml processing?

Hi 👋! knx.yaml isn't a thing per se - no special treatment there. It's just configuration.yaml with an !include, so everything stated in https://www.home-assistant.io/docs/configuration/splitting_configuration/ applies.

#

Id check if there is some duplicate keys in your yaml. Afaik those would be silently overwritten.

knx:
  light:
    - ...
  light:
    - ... # would overwrite the first light key.

Thanks, duplicate key would be detected by the config validation, so this seems not to be the case here

Oh good, didn't know. 👍

#

You can see the actual yaml the integration gets to process in the Knx integrations diagnostics download. Maybe this helps to narrow down the issue.

#

Great idea! In the KNX diagnostic I can see all my configured entities. But some are still not available in HA.

Are you sure they are not just named differently? Did you maybe have had same GAs with a different name before?

inland mica Oct 27, 2025, 9:53 PM

#

The GAs are unique and new. The names are pretty easy and not confusable. I have spaces and umlauts, but this was not a problem for the previous entities

#

ok, I got it

solid tusk Oct 27, 2025, 9:55 PM

#

Yeah that's fine. It's just that entities unique id are generated from (a subset of) GAs.

#

Thus Name is ignored once added.

inland mica Oct 27, 2025, 9:55 PM

#

the entities are just disabled in the knx integration

#

Are they disabled by default?

solid tusk Oct 27, 2025, 9:56 PM

#

This image doesn't tell much.

#

No they aren't.

inland mica Oct 27, 2025, 9:56 PM

#

#

All my newly added entities are just disabled...

solid tusk Oct 27, 2025, 9:58 PM

#

Awkward.

inland mica Oct 27, 2025, 9:59 PM

#

And when enabling I also have to check the "Enabled" and "Visible" switch otherwise they stay invisible

#

This solves my problem for the moment, but next time I add new entities I'll run into this problem again 😅

#

oh, no, it's not true. The enties remain unavailable:

solid tusk Oct 27, 2025, 10:04 PM

#

Check "System Settings" of the Knx integration

inland mica Oct 27, 2025, 10:04 PM

#

yes, the first checkbox is disabled...

solid tusk Oct 27, 2025, 10:05 PM

#

Enable and reload Knx. This should fix it.

inland mica Oct 27, 2025, 10:10 PM

#

Let me check tomorrow after a complete reboot. Right now it still remains unavailable

#

Thanks anyway, seems to be to right track!

Usually reloading the integration is fine.
"Unavailable" means no connection in Knx. But this would show on all Knx entities. "Unknown" is no answer to Read request.
So if the entity was loaded and your connection is fine, it shouldn't show "unavailable".
