TrueNAS Scale - Coral USB Accelerator with the Frigate app

[RKS]

Hello everyone,

I’m currently running the latest version of TrueNAS Scale on my Mini XL+. I’d like to integrate my Coral USB Accelerator with the Frigate app but it seems the USB isn’t recognized by default. Could anyone guide me on how to configure this setup? Thanks in advance for your help!

This is what my apps dashboard looks like - not much CPU demand etc. by Frigate

Here’s the frigate app “home” page, complete with the port mappings I use:

Here’s the first part of the page you get when you press the “edit” button:

and the remainder:

I didn’t do anything clever and I am not an expert so if there’s anything you don’t understand, I might not be able to help (but I can try!).

When Frigate runs, the Coral USB dongle (mine’s plugged into a USB 3.0 port which is what’s recommended) has a lit white LED on it to show it’s working and the Frigate dashboard shows the inference speed of a few ms (9 ms in my case):

Thanks for details, Silly mistake I did not enabled the detectors in frigate config,

@RKS

I did not enabled the detectors in frigate config

Thank you for pointing this out.

For anyone new to Frigate, in addition to passing the Coral USB device to the app, you need to enable it in your Frigate configuration with text such as:

detectors:
  coral:
    type: edgetpu
    device: usb
