Not sure where to start. Recently had Panasonic Evervolt wholehouse backup battery installed. It seems that the only way to access the system information is via Android or Apple apps.
The pinned post at the top of this category has suggestions for requesting new hardware integrations.
I would also love to see this integration.
If anyone is following this. I have been able to figure out that the Panasonic Evervolt is re-branded Solax equipment. More specifically, the I7 inverter is the Solax A1 Hybrid G2. I have been able to reverse engineer some data points, but others will have to wait until sunnier weather (my solar panels are covered with snow). My plan is to put up a github repo with docs and relevant configs on github, I will update this thread with the link once I have it up.
EDIT: Meanwhile, here are some useful links:
