ESP32-C6 Doesnt show on thread visualisation

Configuration Matter/Thread
1

I have HA on a dedicated HAOS Server with ZBT-2 Border Router. I have around 16 Thread devices connected and all show on the visualisation, so far so good. But I have a door sensor on a shed which is close to the limit and drops in and out So I thought I could simply use ESPHome to create a Thread Router on an ESP32-C6. I build the firmware use my TLV to tell it about the network, define is as device_type: FTD. I installed it and can watch the logs over the Thread network ( I assume as thats the only network it has ! ) But I dont see the device on the Thread network visualisation or in the node list on the matter interface. Any ideas why not ?
Core 2026.6.4
Os 18.0
Matter server 9.0.3
OTBR 3.0.1
All I see in the logs after boot messages are repeated lines like this

[18:35:20.061][VV][api.service:020]: on_subscribe_states_request: {}
[18:35:59.532][VV][api.service:020]: on_ping_request: {}
[18:35:59.552][VV][api.service:013]: send_message ping_response: PingResponse {}

I Think I have the answer. The Thread visualisation only shows Matter over thread devices. The ESP Device is connected to the thread network but doesn’t show on the thread visualisation because it’s using the esp API, not matter.

IMHO a thread visualisation should show all thread devices. Not just the matter ones.

I have 5 ESP32-h2 devices running purely as thread repeaters and they dont appear on the nodes list in the gui (dont know why), but they do appear on the thread network visualisation:-

The Matter Server talks to the Matter over Thread devices and gets Thread related information from the MoT devices using Matter Clusters. So yes, a Thread only device can’t provide Thread information to Matter; However a MoT device does report its neighbors, so if the ESP32_C6 is a neighbor it will show up in the map as you’ve indicated (but yeah, not much information to go with it).
