How find double-used GA in HA-Gui-Entities

[pos-ei-don]

I suspect I might have assigned the same Group Address (GA) to multiple entities among my 400+ KNX entities.

How can I find out which entities share the same GA? Is there a column in the Entities view where I can see the primary GA used?

In ETS, I can clearly see how often a GA is used within the project. It would be great to have a similar overview in Home Assistant. Perhaps entities sharing a GA could be listed under the "Related" (Zugehörig) tab, similar to how automations and other elements are displayed.

Hi 👋!

How can I find out which entities share the same GA?

Currently there's no built-in tool for that.

Hi farmio,

First, thank you for all the work done here.

Regarding the lack of a built-in tool: In YAML mode, I relied on text search to find duplicate GAs. With GUI-configured entities, this is no longer easily possible. Is there a way to export the configuration (e.g., to YAML or JSON) for offline analysis?

My specific issue: A heating valve shuts down at night because HA sends a 0% value to its GA, as confirmed by the ETS group monitor. I have already disabled the primary HA entity for this valve, but the 0% value is still being sent once or twice a day. I need to identify which hidden entity or automation is triggering this. The valve is locked after this for 1minute, so just automatically sending the old value via an automation does not solve my problem.

I guess you can look at the integrations diagnostic export. Or look at the json file in .storage, but I strongly recommend not to manipulate this by hand.
