Hi,
I've been using the same dashboard for ages, but it somehow doesn't show anything anymore. The second panel works (Energie), but the first just shows an empty page. This is my YAML in the attachment. Does anyone have an idea?

Whatever the problem is, it seems to be related to the custom:simple-thermostat card.
TL;DR: Double check your climate entity and ensure it is correct/working/etc.
I copied your code then started removing cards to localize where the problem was. Removing the custom:simple-thermostat allowed the code to try to render for me.
Configuration errors are okay in the screenshot since the cards are just mad that I don't have matching entities.
I also wanted to mention that this card has not been updated in 3 years. It's a wonder it has worked this long. Lots of issues reported that appear to go unanswered. All of the Dev's pinned projects have not been updated between 3 to 9 years which is weird because he's active on Github. It is probably safe to assume this card has been abandoned.
Looking at the forks available, you might consider https://github.com/ov1d1u/simple-thermostat. It was last updated 2 months ago and is 5 commits ahead of the original. I used to use this Dev's stack-in-card until he stopped working on it and suggested for everyone to use stickpin's fork instead.
Back again. Using ov1d1's fork didn't fix the problem. Switching the climate entity to one on my system got things working.

Wow, thanks a lot, that was the problem. It's working now 🙂
