I’ve come across some buzz on the home assistant forum that talks about ways to get home energy data into HA. It appears there are configurations within HA to have it upload home energy data from many existing home energy monitor
devices. Those energy monitors typically upload their data to a proprietary cloud service, and the HA interface appears to simply query those cloud services for the data.
Now that PVoutput is supported, and it’s basically free, you can upload generation, consumption, and voltage data to PVoutput and setup HA to get the data from PVoutput. Not sure if there is a way to provide additional data streams to HA using the six additional live data fields available in donator mode. Maybe some HA users could explore this and post some more informed details.
