Home Assistant Integration

Here we can talk about the integration.

Boot speed and storage init

It would be nice to be able to add plugins before starting the bridge for the first time. Unfortunately matterbridge needs some initialization before plugins can be added. This initialization is only done during boot time of the bridge.
Maybe we could add an -init option to init everything needed without starting the actual bridge process. On the other hand i am curious why a slightly longer boot time is that crucial. What delay are we talking about? Even half a second wouldn’t be that crucial for an application which is booted once and then runs forever. With an init option we would also move that delay to the build time of the docker image and the boot process should be faster.

Alpine based docker images

Here is the dockerfile I used to build a alpine based image:
https://github.com/t0bst4r/matterbridge-home-assistant-addon/blob/main/docker/Dockerfile

It’s still WIP, and as you see it’s also using node-18. I‘ve had the same issue using any newer node version with alpine.

Quote from Home Assistant:

Main reason for this, is because in Alpine 3.19 shipped with NodeJS v20, which, at the time of writing, could not be used on armv7 when building Docker images. This is caused by a QEMU bug, which has been known since 2020.

Ok,
just to be sure I understand what you need.
An -init parameter from cli to initialize the bridge awaiting where needed, so you can directly add a plugin inside a docker build.
Is it correct ?
You would call matterbridge -init -add plugin?

[t0bst4r]

Yes, but it could also work in 2 steps if that’s easier:

• matterbridge -init
• matterbridge -add plugin

[Luligu]

I fixed the issue without any parameters.
It will be published tomorrow morning.
Let me know if you need -init for something else.

[t0bst4r]

Thank you!
I'll test that within the next days.

[t0bst4r]

If everything works as expected, the -init step will not be needed anymore.

[Luligu]

I tested adding a plugin with the storage empty and is working correctly.
It was actually a bug that you cannot add a plugin on the first run.
Thanks.

[t0bst4r]

Sounds great, I am always happy to help 😄

I am currently facing another "problem", but I think it’s more a problem with matter.js than with matterbridge:

after restarting the bridge, it looses all active sessions. It is still commissioned, but when Alexa tries to control a device, it does not work in the first place. After logging "session xyz does not exist" several times, Alexa seems to create a new session. After that everything works fine.

I’ve had the same thing experimenting with matter.js without matterbridge, but I am hoping it’s just a configuration problem. Like enabling persistence of sessions. But I don’t know if that is even possible.

[Luligu]

Session XYZ does not exist

This message may appear after Matterbridge restarts, indicating that the controller is still using a session from the previous connection that has since been closed.
After some time, it will reconnect.
In this context, the message is not indicative of a problem.

Hey @Luligu ,

I've got a user who is unable to pair Matterbridge with Google Home, and I just cannot find out why it is not working…

Maybe you could have a short look into it, if you have already seen a similar behavior before?

I don’t expect you to find a bug in my repo. Especially since I am building my own docker container. But maybe you already have an idea or even a solution in mind?

Thanks a lot!

[Luligu]

No worries at all.

2024-06-18 23:16:11.303 INFO UdpMulticastServer wg0: send Unknown system error -126 224.0.0.251:5353
There are thousands of these errors...

Something is not working in his setup.
If mdns doesn't work google or any other controller cannot find the matter device.
I have never seen that error before and have no idea why mdns is not working in his system.
He also has a not up to date version btw.

[t0bst4r]

Hm okay… just asked if there is any special setup like vlan or anything. I just don’t get it. Others work with google home…
