This is my configuration to run Thread/Matter configuration to work together with Home Assistant.
Assumptions:
- enp2s0 – ethernet card id
- 192.168.0.128:7638 – ip and port of socket listening on SLZB-MR3
This works on Debian 13 (trixie) and OpenWRT 24.10.2

Not solved yet – mDNS conflicts (but it looks to not cause any real problems)
