Best Practice User Interface for Complete House


I’m coming from openHAB3 where you have for every room an area card. Once you click on this card another smaller page/dashboard opens with all the sensors and actuators.

In Home Assistant I see only the possibility to bring everything to one or more pages. Is it possible with the area card that it opens additional smaller pop-up pages?

Or what is the best way for a complete house where you have > 20 rooms.

This is possible using browser mod.
