Thank you for your reply, and the time you put in to help me, but I can’t get it done.
if I put slider_style: $ group_slider_style in it, the error message remains. If I put in, group_slider_style: “”, I don’t get an error, but the calendar on the dashboard remains empty. Only get a gray area. What am I doing wrong?
i saw the warning and helped you to get rid of it to make sure that wasnt making trouble.
the widget you try to use is 2,5 years old, which is ages in automation time.
a lot has changed since then. HA is in the meantime a different program, AD has also changed a lot.
there can be many reasons why it isnt working.
i guess you could look at the chrome console for errors.
