Niko HC 2 integration - virtual device (flag)

Hello every body. I am new in HA community discovering the huge potential of HA .
I am running Niko home control 2 and have installed the integration GitHub - joleys/niko-home-control-II: Home Assistant Custom Integration for Niko Home Control II. So far all look’s Ok, I however have an issue to access the state of virtual device in HC2 which should be exposed as switches based on the documentation.
HC2 Integration is version 4.5 on HACS 2.0.1, HA core 2024.10.2, supervisor 2024.10.0 & OS 13.1.

Anyone having face the same issue ?

Thanks
