 Church | Ugh right, it's deconz.
I'll give the unit override a try in a bit. | 10:28:42 |
| Church | hexa: So made the DeviceAllow tweak:
systemd = {
services = {
home-assistant = {
serviceConfig = {
DeviceAllow = [ "/dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2448684-if00" ];
};
};
};
};
Still seeing a connection error.

 @hexa:lossy.network | home-assistant logs? | 10:40:56 |
| @hexa:lossy.network | try char-ttyACM rw instead of the serial device | 10:41:25 |
| Church | Nothing in logs | 10:43:06 |
| Church | Tried that, see this in the unit: DeviceAllow=char-ttyACM rw
Seeing failed to connect still. Nothing in logs. | 10:44:41 |
| Church | Hmm wonder if there's a debug log flag somewhere.... | 10:45:02 |
| Church | Hmm not seeing anything with debug logs turned on. | 10:49:31 |
| @hexa:lossy.network | can you try /dev/ttyACM0? | 10:50:59 |
| Church | Ah there we go... here's something | 10:51:28 |
| Church | Download hass.logs | 10:54:10 |
| Church | Getting a permission denied error | 10:54:23 |
| Church | * Getting a permission denied error trying to probe the /dev/ path | 10:55:32 |
| @hexa:lossy.network | right, can you test https://github.com/NixOS/nixpkgs/pull/135540? | 11:05:36 |
| @hexa:lossy.network | In reply to @hexa:lossy.network
can you try /dev/ttyACM0? or that :) | 11:06:23 |
| Church | Yeah sure | 11:12:46 |
| Church | Same issue | 11:13:40 |
| Church | Let me try adding rw | 11:13:53 |
| Church | Still seeing serial.serialutil.SerialException: [Errno 13] could not open port /dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2448684-if00: [Errno 13] Permission denied: '/dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2448684-if00' | 11:15:59 |
| @hexa:lossy.network | who owns that serial device? | 11:16:38 |
| Church | Hmm, possibly root. | 11:42:29 |
| Church | Guess I can chown it | 11:42:46 |
| Church | Yeah that did it heh | 11:44:43 |
 etu | No group like dialout? | 11:46:38 |
| etu | Dialout is common for serial devices | 11:46:45 |
| Church | Yeah I'd have to see who owns it exactly when I plug back in.
I'm assuming root. | 11:48:55 |
| @hexa:lossy.network | needs less assumptions, more facts 😀 | 12:05:50 |
 @andi:kack.it | just run everything as root ;) | 12:07:20 |
| etu | I've added my home assistant user to the dialout group at some point: https://github.com/etu/nixconfig/blob/main/hosts/fenchurch/services/hass.nix#L411 | 12:11:07 |
| @hexa:lossy.network | the service is automatically part of the dialout group if your config mentions the correct components. https://github.com/NixOS/nixpkgs/blob/df2f45b347d57bdc99aaa96ee227a37f5201c9dc/nixos/modules/services/misc/home-assistant.nix#L370-L372 | 12:20:37 |
