Organise dashboard with KAKU devices

Hello forum,

Let me start with saying that I am an absolute beginner of HA and that my English is not good.
I use a large number of Kaku devices in HA in combination with Lightwave.The consequence of this is that these devices do not have “unique_id” and cannot edit them through the GUI and that my dashboard is messy.

I chose to hide the intity without room I now have an empty dashboard.

Is there a possibility to make a selection of these devices visible…?
