Is it true (and current 2025.6.1 ) that it is not possible to use Google Coral with Frigate?
Intel NUC, HAOS15.2 HA 2025.6.1 (as 2025.6.3 fails for me!)
Coral is recommended for frigate?
Do you get an error?
Frigate is not part of HA so HA version is irrelevant. frigate version has more meaning.
Hi, yes I’m looking to use it with Frigate and THAT is supported, HA Hareware page does show the Coral device but I found a comment in an old thread which says that Coral will not work with HA now.
I hoped I could also use it to accelerate Olalama but it’s also not noted as a supported option.
Just looking for confirmation.
Using latest HAOS (Proxmox VM+usb passthrough) with Coral USB

Seems to be working here. But since im not really using it, I wont guarantee.
I’m running Frigate as an HA Add-On on an old Intel laptop (Generic x86-64) - haven’t bothered to upgrade to 2025.6.3 yet, though::

Seems to be working fine here as well.
well, you see I get both that it’s there and that it’s not

Post your frigate config and maybe ask at frigate GitHub page
Ultimately the coral looks like it’s working and the model error suggests maybe you not using default model. The other tpu fail is weird also so with these two I’m thinking frigate config has a problem
