Hya,
i have a power monitor, and have it with the following card:
type: custom:mini-graph-card
name: W5821 Power Usage
icon: mdi:washing-machine
entities:
- sensor.power_2
show:
graph: line
hours_to_show: 3
points_per_hour: 60
and it works very well.
I want to have the history state output of it in a cvs or any other format which enables me to have it on a spreadsheet, with date, time and measured data.
ANy hint in how to have it?
