Issue adding IKEA ALPSTUGA Air Quality Sensor

Configuration
1

Hello,

New to home automation, I’m struggling to add my first accessory to Gladys.

I manage to add my sensor in Apple Home with a HomePod mini.

However, in Gladys > Matter, the addition always fails with:

Failed to connect on any discovered server

My setup:

  • UGREEN NAS + Freebox Pop

  • HomePod Mini

Is ALPSTUGA + HomePod mini + Gladys Matter supposed to work today?

Thanks.
