Offline entities

[timewolf]

Hi,

i have all entities offline in google home, does the ipv6 a must have requirement?
because i'm a little bit confused how to implement, i'm using HA and the bridge over docker.

I'm using HA OS with home-assistant-matter-addon and I got the same error,
I tried to create a new HOME in google app and I got a different error - required google hub.

Yes, IPv6 is a strict requirement of Matter. You might need to use host networking.

Yes, IPv6 is required and you need to make sure to not have any VLAN segmentation or firewall between the matter-hub addon, your google home hub and your phone (at least during pairing).
Otherwise this won't work reliably.

@timewolf please provide feedback, if anything changes.

Yes, that's a requirement by google home. i've just added that to the docs.

@t0bst4r I have the same issue (offline devices) in the Alexa app.

I have no vlans, firewalls or similar in between my HA, phone echo devices. IPv6 is currently disabled. Pairing of the hub worked and also I can control them.

But they are showing offline, most of time.

I assume IPv6 is also mandatory for my setup?
Is it enought to enable it just on HA? (dont want to mess with it in all my smarthome devices :-) )
Have disabled it back than when i started with my smarthome/home-lab.
Sorry but i am familiar with IPv4 and so lost on IPv6 :-(

It's works for me now :)

My config :

[popy2k14]

I have enabled IPv6 in on my HA and it got an fe80: address.
The issue persist, moste of the time the exposed devices are showed offline.
I am now back to emulated hue for now and will follow this issue.
If any logs are needed, just let me know.

I have this same issue - almost. I'm using Google Home. For me it works perfectly for about a week. Then my Matter devices go offline to Google. At the time that they are offline I have underlying IPv6 connectivity issues - I can't ping out of my HAOS VM with IPv6. I can ping in! This leads me to suspect that HAOS is somehow getting messed up internally and using the wrong interface to initiate outbound IPv6. I can fix the issue by either rebooting the HAOS VM or (maybe) the WiFi access point that my Google Home is attached to. I say "maybe" because I have not yet confirmed this - I've changed the access point that my Google Home connects to and have not been able to confirm that restarting this one will fix the issue. Last time it failed I fixed by rebooting HAOS - with a week or so between failures it takes a while to debug! Rebooting the Google Home does not restore connectivity.

I've asked asked about this the Home Assistant Community and it's getting zero attention. Maybe I asked the wrong question, or in the wrong place?

Do please share the full debug log of a run of matter-hub where devices go offline.
