October 5, 2025Oct 5 This is my 2nd time try to add Matter device to HA docker. In 1st time try (1yrs ago).Install docker "Matter server" and assign it to "Host network"Enable IPv6 and modify some forwarding setting.I haven't setup standalone Thread network, the thermostat joint the WiFi AP as usual, and HA in another VLAN.Due to some reason, I have return that device, so no any Matter device afterward. Below are the previous post which relate to this.Today, I buy Meross smart thermostat, but I realized I was wrong that it support HomeKit or Google Home ( need extra hardware / hub ). So, the only way was connect it through Matter with HA. 😡Due to I don't want run Matter server on separate Host network and enable IPv6. I try something as below implementation ( left side path ).But with whole day trying still not success. So I need back to Matter-server route. Quite interesting this time, I don't need enable IPv6 and setup Matter server in same IoT VLAN were success. There no need complicated setting and it just work.Matter device also connect to same LAN / VLAN ( WiFi ).Install docker Matter-server in same LAN / VLAN.Install add-on Matter in HA and set it to connect Matter-server "ws://192.168.68.23:5580/ws"Request the pairing code from commissioning app. That's allBelow are the log of Matter-server, those error not critical.
