Custom Button-Card Template for EVOHOME_CC / RAMSES_RF

Hi - A couple of questions.
In your example you show a card (Kitchen) which appears to have 2 radiators in the same room. How did you set that up?
Secondly, Can you point me to the code you changed to get the window status to display as it’s not displaying for me and I’d like to check I’ve got the right version? Thank you
