High CPU load on hassio_multicast and homeassistant

oezzi · May 3, 2026, 7:19pm

Hi There,

searched the net and tried to find a solution with AI, but was not suucessfull.
I amne in HA. Installed the HA OS natively on a mini PC.
Now seeing, that the CPU load is around 30-50%:

I aready tried to deactivate the integrations, to see, if there is an influence, but without success.
I am using the latest update of HA OS with all integrations and HACS updated to newest version.

Anyone any idea how to narrow down to the root cause of this high CPU usage?

Thanx in advance

Hi, welcome to the forum!

What happens if you boot in safe mode?

boheme61 · May 3, 2026, 7:54pm

If you “successfully” excluded Apps and integration as source, i would look at Your Network ( Not that i know how many Devices etc You have )
Also try to set Logging== Warning ( It seems to be “Info” )

And Ofcause also first Check Your Logs, either through GUI ( RAW-Log )
Or Through CLI , ha core logs --follow

Multicast is mDNS and Autodiscovery, in specific

oezzi · May 3, 2026, 7:57pm

In safe mode I still have a high CPU load

Nick4 · May 3, 2026, 8:01pm

What kind of CPU does your mini PC have?

As mentioned by @boheme61: check the logs.

oezzi · May 3, 2026, 8:09pm

Hi Nick4 and boheme61,

I changed the log level to warning.
Checking the log in Guis under the “Supervisor” listing I see following:

boheme61 · May 3, 2026, 8:15pm

Now you pasted this twice … and so did i , but im curious ! , Anything interesting outcome ?

oezzi · May 3, 2026, 8:20pm

Hi all,

core logs repeats often this:

ps: unrecognized option: x
BusyBox v1.37.0 (2025-08-05 16:40:33 UTC) multi-call binary.

Usage: ps [-o COL1,COL2=HEADER] [-T]

Show list of processes

        -o COL1,COL2=HEADER     Select columns for display
        -T                      Show threads

don’t know, what it means. Maybe a command I implemented to be done every 20 seconds to see the cpu load. but shouldn’ be the cause.

oezzi · May 3, 2026, 8:25pm

cpu is AMD PRO A10-9700E R7, 10 COMPUTE CORES 4C+6G

boheme61 · May 3, 2026, 8:27pm

Are you doing this “remote” (SSH) , Or direct in the CLI ?

Maybe you’d be better of checking the RAW-core-log in GUI

Ehhh Ok … If you don’t know, there is only one way to find out, remove that command.
How long did you have this HA install running ?

removed it and did not changed anything on cpu usage.
I am using HA since mid of April 2026.

Nick4 · May 3, 2026, 8:39pm

Okay, just wanted to make sure you are not doing this on a some dual core.

~~Did you just install HA now/recently and~~ this happened ‘immediately’ after installing?

boheme61 · May 3, 2026, 8:40pm

I think you should try to check if that cromecast and Airplay stick is your source

oezzi · May 3, 2026, 8:42pm

I installed it mid of april. and due to CPU temperature log, the temperature increased on 23rd of April. I assum, the cpu load also increased at that time.

already deactivated, but did not made any change.

How can I see, what the hassio-multicast is doing?

NET I/O seems to be also pretty high.

boheme61 · May 3, 2026, 8:52pm

Basically You can’t , As Mentioned, it’s responsible for Autodiscovery, and enable mDNS for this

But check this out … im out

Does it do this every time your Reboot HA ?
Starting and after 2min throw errors, and shutting Core down ? or is this because you shut it down/restart ?

Please perform a full Reboot, and then check your Core-Log(RAW) after Reboot
If CPU is still high on Multicast, your either have Network Issues, or some integration/device are causing this

Try , ha core rebuild

oezzi · May 4, 2026, 6:39am

Just for information , there is a Big Difference in REBOOT vs RESTART

Your 2 logfiles looks OK

Still there is a vital reason why The Logs Page by Default Shows the CORE-Log

And , As i said , I’m Out …

NOTE: You started your HA Mid April , and 23 April the CPU increased Temp, What happened the 23rd, you installed something ? Made changes in your Network/Router ?, Have You been in a hurry to just install various Monitoring tools, Integrations etc ?

If i were You, i would Wipe Your Installation, start on a fresh, in a structured manner, And Initially skip Tools/Commands ( Where ever you i.e implemented that CPU monitoring Command ) or ( Restore to a backup, before the CPU increased temp 23April )
Read up upon HA, the integrations you install etc

Your Container “overview” Does not indicate HIGH I/O on neither homeassistant nor hassio_multicast ( In fact 0b )

As i initially said

And in future, Monitor CORE-Log after you installed integrations/etc , basically Supervisor/multicast is hardly the first place to look , “hint the CORE Log is Default shown”
As you seems to prefer “digging in deep” if/when something happens, Use the Debug flag, which you find for every Integration and App(Add-Ons)
