Matter Integration Issue - Leviton D26HD dimmer no longer accessible from HA

[KruseLuds]

The problem

I am using the Leviton D26HD dimmer firmware version 2.1.0 with the Matter integration. It was working perfectly until today. I am getting an error message in my syslog log as shown below:

Sep 25 15:13:40 kruse-pi addon_core_matter_server[754]: 2023-09-25 15:13:40 core-matter-server matter_server.server.device_controller[126] WARNING Unable to subscribe to Node 1 as it is unavailable, will retry later in the background.

Also note, I upgraded the core to core-2023.9.3 from core-2023.9.2 a couple hours ago - I do not know if this is the cause. Thie is the only change I have made to my Home Assistant setup since it stopped working. My setup which is fully up to date is listed below under "additional information".

Also, from the Leviton APP on my phone - it is working fine (but not the Home Assistant app on any device).

What version of Home Assistant Core has the issue?

core-2023.9.3

What was the last working version of Home Assistant Core?

core-2023.9.2

What type of installation are you running?

Home Assistant Supervised

Integration causing the issue

FYI - Update - it started working last night. I had to reboot my router (and then my HA) as my internet connection was not stable, that isssue is gone, but it appears this same problem came back again. So, it appears that "will retry later in the background" 'sometimes' - eventually works. But, it definately is an issue.

[Quentame]

Hi ! The issue may also come from the device Matter over Wi-Fi integration. Was the device also accessible via other admins like HomeKit or Google Home ?

[KruseLuds]

Currently no, for remotely accessing the dimmer, I only use the "my Lutron" Android app, or Home assistant.

[Quentame]

OK. When the device is not accessible via HA: Is it also not accessible via the Lutron app ?

[marcelveldt]

Make sure your network can handle multicast IPv6 traffic (and is not actively blocking that). I am by no means a network expert but these are my discoveries in the last 6 months of troubleshooting Matter:

• In some ocassions it was actually NEEDED to setup IPv6 on the internet router.
• In some cases it was needed to actually disable IPv6 support on the router
• In some occasions it was needed to DISABLE igmp snooping on all/any network switches, in other cases it needed to be enabled
• Some WiFi access points/ecosystems have options to "optimize" or filter multicast traffic, that needs to be disabled.
• Some devices just have very experimental beta support, improving with firmware updates. Make sure that you update devices to the last firmware whenever possible.
• When not running Home Assistant OS or when running HA in a virtualized way we've seen issues with matter devices. Maybe also due to requirements on the network stack in the linux level.

[marcelveldt]

Your log is a bit hard to read but it looks very clear that the Matter controller is unable to communicate with the device. Did you already try a full restart of the HA host ?
