Re: ZM 1.37.61 - ONVIF event messages issues.

It looks like I got myself some answers.
1. Home Assistant - ZoneMinder ONVIF interference
Indeed it looks like once Home Assistant is connected over ONVIF with the cameras, by starting ZoneMinder and attempting also to connect to the cameras through ONVIF the latter coughs and writes "Failed to get ONVIF messages! 28 Connection refused" in the log.
But then if I enter the monitor/camera settings individually for each camera (Console -> Edit Camera -> ONVIF -> SAVE & CLOSE) without modifying any parameters, (I guess) it triggers a fresh ONVIF authentication that is successful:
So both Home Assistant and Zone Minder can communicate simultaneously with the cameras over ONVIF.
2. Motion detection events (in my case Person Detection - that's configured in the camera "intelligence") over ONVIF are received by Zone Minder (also simultaneously in Home Assistant ), but apparently Zone Minder doesn't know hoe to interpret them. I triggered manually (dancing in front of the camera) a Person Detection event and in the Zone Minder log I got:
3. For Camera 1 I enabled SOAP WSA COMPLIANCE in the ONVIF section and haven't got any error in the log. Went outside, manually triggered (dancing in front of the camera) a Person Detection event and got in the Zone Minder logs the following (focus on zmc_m1):
Meanwhile (in parallel /simultaneously) Home Assistant was correctly receiving through ONVIF the Person Detection event - see screenshot with the timestamp:

In Home assistant I'm using the "standard" ONVIF integration - source code is here (it's open source - maybe good for inspiration - don't be shy
):
https://github.com/home-assistant/core/ ... ents/onvif
I noticed in this thread that there were some issues with the ONVIF implementation in the cameras FW - saw a reference to a TP-Link Forum thread. When I bought my TAPO C520WS V1 cameras back in February 2025, my "stock" FW was 1.2.10 Build 241025 Rel.55515n and the Home Assistant ONVIF integration worked perfectly fine with it, no issues whatsoever.
As a side note, I received today word from TP-Link, they're saying that the smart mode (white LED light) during night is not working properly (I understood from their long blabla that the luminosity is too low) and the camera might miss movements (won't record) so they won't fix it. They offered a refund. I guess I'll stick with the IR LEDs only during night. .. a flawed product
