Silicon Labs Multiprotocol container does not start

Configuration Zigbee
1

Hi all,

I’ve been digging for a bit but can’t seem to get both Zigbee and the Open Thread Border Router working at the same time. I successfully flashed my Sonoff ZBDongle-E to the RCP firmware, which is then recognized correctly by the container. Settings are set to use device /dev/serial/by-id/usb-ITEAD_SONOFF_Zigbee_3.0_USB_Dongle_Plus_V2_20230505161412-if00 and 460800, software flow control and I disabled automatic flashing.

Seems like the otbr-agent is crashing due to [C] Platform------: platformBackboneInit() at backbone.cpp:62: Failure - but I really can’t find anything relating to what that might indicate.

When I disable the “Enable OpenThread Border Router” the Zigbee part works just as well as it did in dedicated ZHA mode - heck, I even managed to successfully restore the backup that was made (happy surprise).

All suggestions are welcome - this is quite easily reproducible as well.

If I had to guess, I’d say this is the reason for the “platformBackboneInit() at backbone.cpp:62: Failure” as the “Backbone” is related to the Ethernet side of the OTBR.

As to why it can’t find a primary network interface, I don’t know, but I would guess its looking for a physical Ethernet interface on your Home Assistant and can’t find one.

Thanks for thinking along.

Actually, this device (MaxMini B1 Plus - Mini PCs - BMAX) is only connected via wired, not wireless (even disabled in EFI to save power). No virtualization layers on top, just pure HASS OS on the eMMC of the device.

I think the issue is probably related to this:

[10:16:10] WARNING: No primary network interface found! Using static eth0.

The interface naming in my HASS installation is eno0 as the NIC is onboard. Since the addon_core_silabs_multiprotocol is using host networking it’s attached to the default network namespace, where there is no eth0, only eno1.

Ideally we’d have the otbr-agent looking for any eth *, * eno *, * ens * or em * type of pattern here. Do you happen to know the right place to file a bug for this?

edit: found the configuration file:

➜  ~ docker exec addon_core_silabs_multiprotocol cat  /etc/default/otbr-agent
# Default settings for otbr-agent. This file is sourced by systemd

# Options to pass to otbr-agent
OTBR_AGENT_OPTS="-I wpan0 -B eth0 spinel+hdlc+uart:///dev/ttyACM0 trel://eth0"
OTBR_NO_AUTO_ATTACH=0

It would be great if we could have (parts of) OTBR_AGENT_OPTS exposed as per the container variables for the silabs-multiprotocol container.

I would file it for the Add-On. Its possible that the problem lies upstream with the OTBR, but not sure.
