I was wondering if someone could help me out on getting following config inside Home Assistant.
Currently I pull in my PV solar energy generation through the https://www.home-assistant.io/integrations/pvoutput/ component into Home Assistant and with help from the Mini graph card I get a nice week overview of what each day produced.
But I would also like to see an accumulated figure of total power generated since a given date. In other words the result would be for example : Generated kWh : 769 since 2020-04-20.
The date value would be something I need to enter in and will change over time.
Since the PV Output component has no query capabilities, I was wondering if this calculation can be done purely in Home Assistant? And how… of course.
