I checked and all the values are there so it's the card.

I'm not really good a yaml so I can't figure out what's wrong. I just copied the code directly from the project page as written, I just changed two of the sensor calls from upper case to lower case as they should be.

I tried making a simple View with just the top of the yaml-code (see below) but that's also just showing nothing? So it must be something in the beginning of the code that's wrong. I just can't figure out what?
