You could use a Super Tile which gives you full control over the layout of items within the tile.
In theory, you could even just have a single Super Tile on your dashboard that fills up the full height and width of the dashboard as the Super Tiles scale up and down based on the relative position of items within them.
You could add your floorplan as a ‘static icon’ and make it the lowermost layer, then add whatever elements you want on top of that.
Yes, that’s basically just a loading placeholder and will also show if the Super Tile doesn’t exist anymore… though we perhaps consider having a separate loading indicator.
You can alternate which icon is shown, but you can’t currently style the individual items within a super tile. Some people have chosen to upload their own icons and use those for the different states. For example, a generic top-down view of a lamp that’s off and another top-down view of a lamp that is glowing.
There’s a feature request for styling the individual parts of a Super Tile that you might want to cast a vote on and comment with your use-case to bump the thread here:
It’s a shame the ? cant be replaced with a blank screen or even a loading message
Im intrigued by what you said about the lamp glowing, would anyone have any ideas hoe to do this? or could you any more? I know its possible in HA but dont really want to go that route - i have a life
