Hi Community,
About 2 years ago I started this conversation, lately I saw more and more topics on this subject. Special lovelace dashboards, automations, blueprints and even complete add-ons and integrations. I was also planning to do some development work, with the help of AI, to create an integration.
But… then I came across the integration of @traktore-org (Guido)
This integration called SEM (Solar Energy Management) has a big potential to achieve what I was hoping for 2 years ago.
It is nearly selfconfiguring itself, including the dashboards. It has a tight integration into HA, it’s automated and user friendly.
Guido is very responsive and all suggestions, feature request and bug are implemented in hours (max a day)
The name Solar Energy Management doesn’t tell the whole story, because it’s much more than Solar alone. So @traktore-org maybe you should change the name to Home Energy Management System or Home Energy Assistant
So I encourage anyone of you the have a look at SEM → GitHub - traktore-org/sem-community: Intelligent solar energy orchestration for Home Assistant — EV charging, battery management, multi-charger control, heat pump SG-Ready, 15 languages, 1100+ tests · GitHub.
There is also a post on the HA forum on this → Solar Energy Management (SEM) — Smart solar + EV + battery orchestration
So again a big tumbs up 
for @traktore-org, please support him to make this integration even better.
