Addons RAM sensor always 0%

[Zeunas]

The problem

I need your help troubleshooting this issue...since mid December all of my addons have stopped showing any RAM usage (always at 0%, if only...), although CPU usage sensor is working fine. I mean, no way Frigate would show RAM at 0% all the time...something is going on but I can't find the root cause. I am running HAOS latest version in a Rasp pi 4, I ran an ssh command 'ha supervisor repair' in case it was something related to the Supervisor but no cigar...I have googled for similar issues but can't find anything, so now I am resorting to your assistance. Any suggestions?

I believe the issue is with the supervisor as that's the one that provides the CPU and RAM usage sensors...

What version of Home Assistant Core has the issue?

core-2025.1.2

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant OS

Integration causing the issue

Supervisor?

Example YAML snippet

Anything in the logs that might be useful for us?

Supervisor logs don't show anything related to these Addons RAM sensors, not sure where else to look for possible errors.

Additional information

I also see this on my Homeassistant test system which is based on a Raspberry Pi4B.
But I think it is a problem with HA-OS 14.1.
If I downgrade the test system to HA-OS 14.0 then I see plausible sensor values again.

Interestingly, I don't see any problems on an HA-OS VM with HA-OS 14.1, so the problem seems to be related to the host architecture.

docker info shows almost identical output under 14.0 and 14.1, but with 14.1 I get 2 warnings:

WARNING: No memory limit support
WARNING: No swap limit support

docker stats --no-stream doesn't show mem related values under 14.1

1. downgrade from 14.1 to 14.0
2. upgrade from 14.0 to 14.1

Interesting, at least there's someone else with this problem...do you have any suggestion on how yo test this with my set up to see if i get the same warning message?

[Baxxy13]

You can use the "Advanced SSH & Web Terminal" - AddOn.
Just start it and type: docker info

The warnings are at the bottom of the output.

[Zeunas]

Of course...what a lemon...thanks! Yes I get the same output.

[Baxxy13]

Found this one: home-assistant/operating-system#3765

So downgrade to 14.0 or wait for next HA-OS... to fix.

[Zeunas]

Thanks! Looks like they are on it!

I have the same issue on a pi4B. But it works fine on a pi5.
