Adjusting the y axis scale works perfect, thanks again!
Some quick tests:
-
Graph of last 7 days (forget about the titel, this was to test) with 2 measurements. So two graps stacked on top of eachother: solar power (W) and electricity usage/return (W).
The peak in energy usage is 4 days ago when charging the car. -
The same graph, but in Homey made one change: flow card to send insight of last 1 instead of last week.
I need to think about the x-axis. Would like more round values. Thinking about it: I could just run the flow in Homey every 15 minutes or every hour 
That should be sufficient as well and result in more “round values’”
