Discovering Entities - WebSocket connection closed

[manuel-rw]

I am unable to link the entities to the Zone Configurator:

The following error is logged within the Addon logs:

I removed sensitive data with XXX in the logs. No proxy used, stable internet connection, no issues with other add-ons.
The entities are there and the sensor is working:

Installation method Home Assistant OS
Core 2026.3.3
Supervisor 2026.03.2
Operating System 17.1
Frontend 20260312.0

Hello, any update on this?
I cannot use my sensor at all currently. I bought this sensor specifically for zone control.
It currently is turned off and removed since I don't use it.
If this is not resolved, I will request a return.

Hey, sorry I didn't notice this was breaking your setup.

Can you please go to Home Assistant and check for updates, then go to Settings > Apps > Everything Presence Zone Configurator and press the rebuild button - that should pull down the fix I just pushed that I am hoping will fix this.

Once rebuilt, try again, does that help?

[manuel-rw]

I rebuilt the app and tried again.
The same error is shown but there are more logs now.

Just to confirm; the app does not connect over the domain that HomeAssistant is accessed from but is connecting internally (host of HASS), correct?
I want to make sure that my reverse proxy is not breaking anything.
I had a look at Traefik logs and no requests are being dropped; so no sign of any issues there.

v2.2.1 still has the same issue

[EverythingSmartHome]

Thanks for the logs, taking a look

[EverythingSmartHome]

I think I see it now from the logs, do you have a particularly large HA setup with lots of devices?

PR incoming if you want to test. Once merged, can you try the same rebuild process I described above?

[manuel-rw]

I have a large instance, yes. How do I test? Rebuild?

Same way as here
