core: Somfy Cloud does not see all devices

The problem

I have a Somfy Tahome and used the Somfy Cloud integration to set it up. Only one device which is the vertical zip screen is visible, plus the Somfy Tahoma box itself.

However, that vertical zip screen is connected to a Sun Screen which is horizontal and in the arms are dimmable Led Strips, and I also have a Somfy IO Sun Sensor connected to it. These are all not shown in Home Assistant.

How to fix the Somfy integration?

Anything in the logs that might be useful for us?

I do not know any Yahml etc, I am an IT Application Manager and can have a screen sharing session if you would like to investigate.

I have it installed running as a core application on my Windows 10 laptop.
