I am on sw Version 0.87.1 rather new with lovelace.
I have a number of number sensors integrated showing PV production and Home Energy consumption. I read them through from my SMA inverter using pysma.
For some reason I can’t get line graphs with the lovelace sensor card. It does always display and update my sensor values but no chance for the line. I tried different themes then to see if I am drawing white on white but without success.
There should be not much to do wrong. This is my config of the card, Can anybody advice??
type: sensor
graph: line
theme: default
entity: sensor.power_from_grid
detail: 2
hours_to_show: 3
