Open Source Self-Hosted Home Assistant home automation with an interface to a Victron Solar System

Home Assistant is an open source self-hosted home automation tool that puts local (not external cloud) control and privacy first. My system is running in a Docker container on a machine at home.

Home Assistant is more than just the monitoring and managing of smart home switches and lights. It has powerful automation that can be triggered by all sorts of events or device states to notify you, or manage even solar systems, garage doors, and much more. For example, I have an automation that announces it has started to rain so we can get the washing off the line before it gets too wet.

In this video I show what my HA dashboards look like, and how I managed to read lots of information via the universal Modbus TCP protocol from my Victron solar energy system, and to also write data back to the Victron system to change the battery minimum state of charge values from HA (or other registers).

I have shared my config files on a Github page so that it is easier for others to replicate some of the same functionality (without spending 4+ hours like I did on a single value statement line).
