Edit: Easy done… 
Created a entity:
- platform: local_file
file_path: /config/www/img/snapshots/parkering.jpg
name: cam_parkering_snapshot_latest
And using a Automation when Frigate senses a car … bang…
Sending that snapshot to “plate recognizer” and a pushover sends me a notify with snapshot and plates. 
Can anyone explain this event, it seems the score is higher in the event:
than in the best image:
Any tips on eliminating false positives like these? I have max and min area set per camera but this camera covers some distance so object far away appear smaller. Is Zone object filters something added to the feature list?
OK thanks I’ll give this a try. I found the sample frigate config on the site. So the process would be:
Is this correct?
This is how I did it
Hi, I’m not quite familiar with input boolean.
Did i get this right?
/config/input_boolean.yaml
input_boolean.block_notify_car_porch:
name: Notify car porch
icon: mdi:car
input_boolean.block_notify_luar_dapur:
name: Notify luar dapur
icon: mdi:kitchen
Ok, i’ve corrected it
block_notify_car_porch:
name: Car Porch
icon: mdi:car
block_notify_luar_dapur:
name: Outside Kitchen
icon: mdi:food-turkey
I’m getting this error with invalid configuration
Unexpected error calling config validator: unhashable type: 'NodeListClass'
I searched around apparently there’s too many condition?

Following up on my previous post and tried the PoE Pi4 with the USB Google Coral and a USB NVMe drive. At least with the combo I had, it was drawing too much to boot. Will try again when the PoE+ hat comes in. Without the NVMe plugged in the switch reports it drawing about 5w-8.5w at 54v, with the NVMe was capping it around 9.3w, this is also a class 0 PoE hat so guessing it was stopping it at that end. It is a PoE+ compliant switch which is barely at 1/2 capacity as well. The official Pi PoE hat reports as Class 3, however I’ve had 3 out of 6 fail, so was using a different one which looks a bit lower power output capability.
@konna, raspi4 can manage h.264 decode till to 1080p, have a look to the previous post Local realtime person detection for RTSP cameras - #4774 by bremby
Hi, i am getting the same problem. Can you please explain the extra steps from the google coral tutorial that you did? Thank you
Sure, in my case I am using the M.2 version of the Coral and I followed these instructions to install (I’m using Debian - Proxmox):
Yes, i have also followed this tutorial but i am having the same HIB errors that you were having when i try to run the example.
Thanks for this. I managed to make a lot of progress.

From memory my issue was the gasket-dkms and libedgetpu1-std packages weren’t being installed (I wasn’t paying attention to the output of the ‘sudo apt-get install gasket-dkms libedgetpu1-std’ as there were errors due to not have the kernel headers installed).
Installing the kernel headers package first cleared this up and it installed successfully.
Had this a few times… reboot host, and do pveupdate and pveupgrade
Did you install the kernel headers in the Proxmox host or the LXC container or both?
Just on the Proxmox host. I actually use Docker on my Proxmox host to run Frigate but I imagine it would be the same for running it in a LXC container.
Thanks but still no luck, I did the following:
cat /usr/lib/udev/rules.d/60-libedgetpu1-std.rules

It seems to identify the Coral USB and process the rules but not actually do anything either. And the rest is past my understanding of udev.
Finally, do you have any issues running docker directly on the promox host as I’m tempted to go down this path rather than messing with LXC if I ever get the coral detected properly.
Did you have to do anything special to get it running on Synology Docker with Coral? I’m stuck at Frigate not detecting the usb-tpu. Any tips would be greatly appreciated!
Managed to get it working by running something that needs the TPU. This triggered the udev rule and switched the device ID over to Google. Also changes the USB bus numbers but as long as it stays in the same port, it remains the same from then on (at least after a few reboots).
Now I’m on my final issue, getting the graphics to work. I’ve upgraded my kernel to 5.11 which is supposed to suppot AMD Renior graphics but I’m getting:
ffmpeg.livingroom.detect ERROR : Guessed Channel Layout for Input Stream #0.1 : mono
ffmpeg.livingroom.detect ERROR : [AVHWDeviceContext @ 0x562a566e7e00] Failed to initialise VAAPI connection: -1 (unknown libva error).

@blakeblackshear any ideas? I have seen mentions of needing a recent mesa driver (20.3+) for decoding but not sure if that helps here.
From my understanding it means that 1080p is the maximum resolution. I’m having 720p so I suppose it should work without any errors. Thanks anyways!
Is there a good tutorial how to install the coral (USB) on a raspi 4 running Home Assistant OS?
Didnt found something in this thread.
€: It seems to be easier then I thought. Just plugged it in and added the coral as detector and it seems to be working.
The integration shows me a inference speed from the coral and the video is running. Waiting for some movement in front of the camera.
