Hello,
The Mitsubishi heat pump provides the cumulative consumption (since the pump installation? since the MELCloud account activation? whatever). You can see the graph starts with 837 kWh, and goes to 838 kWh.
Here is the configuration snippet:
type: custom:apexcharts-card
hours_12: false
header:
show: true
title: A/C Power Consumption
show_states: true
colorize_states: true
span:
start: day
series:
- entity: sensor.main_energy
Is there a way to transform this into per-hour consumption?
Basically, every hour I would like to display the bar with
the height = (this hour cumulative consumption) - (previous hour cumulative consumption)
