Evohome sensor not display Graph

I have a weird issue that I am unable to solve. Temperature display fine on frontend but unable to graph any of the climate entities. Anyone able to assist me.

This question is supposed to be asked in the already present dedicated “mini-graph-card” thread.
In short: the card’s syntax is wrong, check docs in GitHub for a proper placement of the “attribute” option. And this may be not the only reason for the issue, just the most vivid error.
