This site aims to be a beginners guide for setting up EMHASS with Home Assistant. It specifically targets those with a Sigenergy system with Amber Electric pricing. In the end you will have home assistant automatically controlling your battery, optimizing when to charge and discharge to and from the grid based on pricing and weather forecasts. This is akin to Amber’s SmartShift, but you have full control and able to run locally.
Disclaimer
I do not claim to be an energy expert and this guide is still a work in progress, but it does provide a complete working solution. I am just a software engineer sharing my learnings in the hopes of helping others as I found EMHASS quite thorny to begin with.

Getting started
First we will start with an overview of the general architecture of how everything fits together.
