Reolink Duo PoE entities problem

[eaves33]

The problem

Hello everyone.
I have my 9 reolink (two of them are Reolink Duo Poe, the first version of reolink duo) cameras in HA, integrated via NVR. For this tipe of camera two devices are created (one for each camera lens). In Reolink Duo 2 PoE only a device is created, containing both lens images combined.

Everything was fine until about 3 weeks ago when entities from this type of camera have started to become duplicated time by time. That means that some times a new entity is created for a camera adding "_2" in the end of the name. This makes my dashboard to stop working.

Can you figure out what can it be?

Did you downgrade your HomeAssistant version at any point?

[starkillerOG]

Could you share your diagnostics file for the reolink integration?

Hi,
Same problem here, Duo PoE connected to NVR, happens every restart/reload, even if you delete the "ghost camera/channel + entities" it comes back next restart and also recreate camera/channel 2 with default area, first camera/channel is always intact.
I did use restore about a month ago when the "Reolink- reload Integration deletes and adds again devices #131421" occurred.

there you have! Hope you can help me. Thanks in advance

@eaves33 I see you have the "reolink_discovery" custom component installed.
Could you start by removing this custom component and see if that helps?

If it does not help, I will need to get a debug log from the startup process:
Enable debug logging, then restart the reolink integration (or the full HA), wait untill the reolink integration is fully loaded and then wait an extra 2 minutes. Then disable debug logging and post the resulting log.txt file here.

I deleted the custom componen. Probem persists. There is the depuration log.

I think i found it. Now I downgraded the firmware version of NVR to the previous version and, for now, it seems to be working.

@eaves33 your debug log revealed an issue which could explain this behaviour.
I have fixed the bug in this PR: #135035.

It should be fixed in HA 2024.1.2 which should be released Jan 10th

Thank you very much. I also noticed something now. Integration is ok and official Reolink nvr app shows all recording in the time line but if I add a camera card to the home assistant dashboard the Reolink nvr starts rebooting time to time (if I open dashboard card of camera in homeassistant) with data loss. If I remove the card (although I keep Reolink integration in HA) the Reolink nvr doesn't reboot anymore and I have no monentanial data loss in nvr.

[starkillerOG]

That is weird, maybe you are overloading the CPU of the NVR with two many streams at the same time.
I noticed you have 10 streaming channels on a 8 channel NVR. (The 2x DUO take up 4 stream channels).
Although this is allowed, I think this is the absolute max the NVR can handel and is 2 more streams than normal when not using DUOs.

Maybe the extra stream (or maybe even multiple streams if you have multiple camera cards on that dashboard) is pushing the NVR over the edge and overloading the CPU causing it to lock up and crash.

What is the CPU load on the NVR?
If you connect a screen and mouse to the NVR you should be able to see the CPU usage (I don't remember where exactly in the menu, but somewhere in the settings and then info or something)

[starkillerOG]

The data loss is properbly just because the NVR is rebooting itself after the crash. The rebooting always takes a while (should be max 2 minutes or so). during the reboot it will not be recording causing a gap in the recording.

[eaves33]

Makes sense. But why doesn't it overload with 10cameras if I don't have HA card? And in fact it already worked like that for a long time. Really strange. I will see cpu usage and let you know. Thank you for your patience

[starkillerOG]

The fix has been merged and will be available in HA 2025.1.2.
