Cannot add PLANT STATUS Card, "config is not supported" error


I have a Mi Flora Plant sensor and I can read out all sensors data. I also created a plant element in my config. In the “Unused Entities” menu I see the element and it shows all sensors.

When I try to add the “PLANT STATUS” Card I get the following error:

What am I doing wrong?

Plant Card - Red status?

@Hackmett, I dont use hassio but in normal ha it will always start like that until you specify a plant entity as follows (in your case plant.daenerys):

Plant Card - Red status?

Thanks, that did the trick!
