ZBT-2 to TrueNAS app

[lofty grail]

Has anyone been able to pipe the zbt-2 into the home assistant truenas app? I've been trying for the past few hours and not had much success.

I've set up the device going from the /dev/serial/by-id/zbt2etcetc-if00 to /dev/ttyUSB0, I've confirmed within the home assistant container that the device is there, and using stty I can talk to it and retrieve the 921600 baud rate so theres definitely some sort of communication happening but I can't set it up in home assistant either through it just showing up or manually in the ZHA integration, it just doesn't seem to communicate. There's nothing in the logs as far as I can tell, am I doing something basic wrong?

if its passed through correctly it should auto detect it and start a onboarding setup.

What version of home assistant do you have running?

[lofty grail]

Installation method Home Assistant Container
Core 2026.2.2
Frontend 20260128.6

Should I maybe pass it through to a serial/by-id device rather than a plain tty device or does that not matter? Lsusb in the container shows it up properly

I haven't done it myself but from some examples I have seen about the place I believe that you are on to something there.

random example I just pulled up in a search

         - /dev/serial/by-id/usb-Nabu_Casa_ZBT-2_2F9R9YYDGTMH-if00:/dev/ttyUSB0```

so yeah, I think the serial/by-id is the way to go.

Then it should pop up on the devices page to add which starts the onboarding.

No luck unfortunately

Maybe it's udev rules

It's usually udev rules with serial and Linux lol

This indicates it's going from the serial by I'd but being mapped to just dev/ttyUSB0 I think

That looks like all the permissions are in place for any user to write to dev/ttyUSB0

I've created a udev rule and tried mapping it to dev/ttyACM0 inside the container too and it just will not detect it, really running out of ideas
