Reolink causes CPU Load in Proxmox After Updating to 2026.8.3

Configuration

Hi everyone,

I updated HA from 2026.7.4 to 2026.8.3 this morning and switched from card_mod to UIX at the same time. For the most part, everything worked fine. But now I’ve noticed that

a) Spook reports that the “Detection Sensitivity” entity is no longer present, and
b) my Proxmox is showing a CPU usage of about 14–18%; normally it’s around 3–5% (my Windows 11 VM is at 4% usage)

I haven’t changed any of the Reolink settings, but I did try switching from RTSP to RTMP. The change didn’t help. If I disable the cameras, the CPU usage does go back down, but that’s not really a solution.

Question 1: Have you noticed this as well?
Question 2: Is there a solution?

  • HA Version 2026.8.3
  • Proxmox is up to date
  • 2x Reolink E1 Zoom
  • both cameras stream “fluent”
  • Changes: None except for an update and switching from card_mod to UIX

Thanks for your help, and have a wonderful Sunday. :wink::man_raising_hand:

The CPU increase likely comes from Reolink integration changes. UIX probably isn’t responsible for the higher CPU usage. Check recent Reolink-related changes and Home Assistant logs. Also verify video decoding or transcoding isn’t occurring. The missing sensitivity entity may reflect integration changes.

Hi Ronny

Do you happen to have “preload camera stream” enabled?

If so, try disabling it for both streams. If the CPU load drops as a result, you are likely affected by this issue.

Hello.

Thanks for helping me. I haven’t change any configuration in Reolink Integration. The higher CPU usage comes with update to 2026.8.3.

In the log I found:

Error from stream worker: Error opening stream (Invalid data found when processing input, rtsp://****:****@192.168.10.91:554/h264Preview_01_main)

@jim_os : I haven’t the option at my Reolink E1 zoom. In my dashboard I use fluent not main or somethings else.

Okay, I don’t have a Reolink E1 Zoom here, but I do have various cameras from different manufacturers. For all of them - including, for instance, my Reolink Doorbell - I have the option to either preload the stream or not. As far as I know, this is a Home Assistant feature and has nothing to do with the camera or the stream itself.

However, if you really don’t have this HA setting available for a particular camera, then unfortunately I can’t offer any further insight into your problem. That said, what is definitely true since Core 2026.8.x is that preloading the stream - for whatever reason - now places a significantly higher load on the CPU (depending on the number of cameras and streams) than was the case prior to that version.

Edit: Click on the camera’s corresponding stream sensor - for example, for a Dahua camera - to access the stream. Then, click the gear icon in the top right corner;

the screen that opens should allow you to enable or disable stream preloading.

By default, however, this feature is disabled.

And this applies to every stream, so it doesn’t matter which stream you use on your dashboard. :wink:

Nethertheless, thanks for try to helping me.

Have a nice Sunday.

Thanks a lot. :+1:

It was enabled in the main stream. After I disabled it, the CPU load dropped immediately, and RAM usage also went down right away. I would never have looked there.

You saved my Sunday. :wink:
