I searched the forum and didn’t find an answer that suited my needs so posting my version of the solution.
I try to no use custom components or cards and when searching for a blank or spacer card to use in the grid card everything seemed to be pointing to custom solutions. My solution is a bit of a hack but it works.
To get the blank spaces in the Master Bedroom and Window/Door Status areas below I used a button card with a generic entity, no name, no state and no icon. Then turn off the tap and hold actions and viola, a card that does nothing and shows nothing!
UI based setup Example
I copied the config for cards 2 and 6 in the master bedroom grid. Same goes for cards 2 and 3 in the Window/Door Status grid.
