Seeed Studio XIAO ESP32C6

I am trying to utilise a Seeed Studio XIAO ESP32C6 to report voltage within the SmartThings ecosystem. Unfortunately, I can’t even get the thing to connect!

It connects easily to a “dummy” Home Assistant setup running on a Raspberry Pi but isn’t recognised by the SmartThings Hub (V2) using any of the Example sketches I have tried.

Has anyone managed to use one of these boards successfully with a SmartThings Hub?

I don’t know about your specific setup, but I’m running Aeotec V3 hub and recently connected a Tasmota flashed Shelly 2PMgen4 via Matter and wifi (yes both), and an experimental endpoint. The 2PMgen4 has the esp32c6.
