@PeterGrace - I had the same issue. Reason was that the entity did not exist.

I can confirm that this error occurs if one or more sensors in your config don't exist. In my case, I had a linkquality sensor configured which was disabled and as a result it caused the whole template to fail rendering. Thanks @Symbiot78 !!!
