Dual Battery Automation in Home Assistant (Part 2)

This is part two of my Mastek Battery Automation project with Home Assistant. I added a second battery, improved parameter handling in the Home Assistant GUI and overhauled the automation & balancing script for (almost) zero grid export. It works better than ever. I wish I could continue working on this project, but there really is not much more to do, because it is perfect! I used a header picture of an open pit coal mine I took in 2008 near my home town. Here is still hope that this centralized and polluting period of humanity will come to an end soon.
