Home assistant yellow coral usb

Hardware
1

Hi, anyone else with home assistant yellow having problems using frigate and google coral usb? I’m trying to decide if this is a hardware problem or software.

Hardware:
Home assistant Yellow Kit with Power Supply
1x Google coral usb
1x Sabrent USB 3.0 Hub Powered (model no. HB-UMP3 )

Other useful info
I’ve no other usb hardware attached. I transfered my installation from a backup but didn’t have frigate running previously. I installed the full access version of frigate with protection mode disabled.

I ran frigate on a backup raspberry pi 4 fresh install of home assistant and same google coral attached over night without any issues.

Thanks in advance for any help.

Does it need usb hub? Test without

EDIT

Definitely a power issue with Coral

Thanks for the reply. I’m not sure just assumed it does require powered hub. Tried your suggestion plugging it in direct no usb hub. It wasn’t found at first on restarting frigate so I rebooted home assistant and it picked it up. It ran ok for few minutes then stopped with the below log

Verify power to both pi and coral is good. Power supply may be providing too low current output creating this issue

5

Well the coral ran fine on a regular pi4 without usb hub so would say fault doesn’t lie there. I had a spare 12v DC 2A barrel jack plug but that’s same problem as before. I’ll need to look up how to safely test the power supply I’ve never done that before.

I’m not only person with this problem it seems. Found same fault being discussed on reddit [here] but no solution (https://www.reddit.com/r/homeassistant/comments/y0thjv/ha_yellow_users_any_luck_with_frigate_coral_usb/?sort=old)

The HA Yellow likely doesn’t provide enough power via USB to run a Coral directly. Also, depending on the version of the CM4 you use with your Yellow, it could be interfering with the Coral as the Coral is susceptible to interference.
I have heard a few users having success with having the Coral 20 inches or so away from the Yellow, on a proper powered USB Hub with an extension cable back to the Yellow. Make sure your USB hub can supply the power though. Some cheap powered hubs don’t meet the USB specs and don’t give enough power. The Coral tends to like a bit of juice to run properly.
I would probably run Frigate and the Coral on a different device though. The CM4 is still just a Raspberry Pi device and not really recommended for Frigate. You can still use the Home Assistant integration and run Frigate stand alone on another machine.

@TomNook
i am currently also trying to get the coral usb to work on the home assistsant yellow in conjunction with frigate.
It is not even recognised in my case.
Do I have to install anything in advance, or is it enough to install the corresponding drivers with frigate?

I cannot install the libary the yellow say no such file or directory…

Is it finally working for you now?

8

What is the end verdict on this?
Is the Google Coral USB a dead cause on the HA Yellow even if you try and mitigate power via external usb hub or is it doable?

It seems I finally got my hands on a Coral but if this isn’t working I will have to return it (once I get it shipped)

9

I was about to test Coral USB on Yellow. Found this thread, then the next search was a blog from Nabu Casa stating that the M2 Coral was NOT compatible, but the USB was…

…However, if you still want to use the Coral accelerator, Home Assistant Yellow is compatible with the Coral USB accelerator stick, which requires a USB-C to USB Type A cable…

10

I got my coral the other day and I have been trying to run it via an powered usb hub and a extenstion cord to get it away from the Yellow since it apparantly gets intereference from it.

Currently, Frigate finds the TPU!

[2023-04-01 16:07:55] frigate.edgetpu INFO : TPU found

For that to work I need to run the “Frigate (Full Access)” and have “Protection Mode” turned off.
BUT, I am getting other crashes sadly:

Will see where I end up with this.

What are your frigate settings for detection?

12

Pretty basic.
Have tried the 0.12.0Beta version of frigate without any difference.
Initially I had five streams set up, all the same resolution, then it crashed more or less immediately on startup, if I run with one camera it manages for a couple of minutes (10+) before it gives up and throws the same error.

Have not increased the gpu_mem as recommended in the docs though ( Installation | Frigate ), havn’t found a way “in” with the Yellow to do that. Thinking of reinstalling the whole thing but I am not to keen on doing that.

Any advice/recommendations?

any final verdict regarding hoas yellow and usb coral (w/ usb hub)?

14

it doesn’t work. the PI4 simply doesn’t have enough power to run Frigate appropriately and the usb port doesn’t have enough juice to run it reliably. Avoid.

15

Prety sure its not a power issue but its a usb speed issue. HA yellow is usb 2.0

16

Has anyone tried the USB C port? I have a USB pwréd hub with 2Amp power supply.
My Coral TPU powers up and completes Init. But I never get Frigate to ‘see’ or detect the TPU.
So is the solution to run (yet) another Home assistant image on a spare Pi5 ?? and us the remote HAOS add on ?
