Thanks again @fbradyirl – a few days ago I uploaded a GIF showcasing my extended version of the energy visualization.

Initially, I was planning to release the updated YAML code directly. However, since I personally use a KOSTAL system, I had to backport the view for SIGENERGY users so they could also benefit from the improvements.

During that process, I realized it would make far more sense to turn this into a full Lovelace custom card, offering better flexibility, user configuration, and platform independence.

⸻

✅ Currently working features (YAML version): • Real-time animated energy flow with direction control • Automatic state detection (e.g. inverter inactivity) • Lines automatically turn off when no energy is flowing • Visually optimized for both dark and light mode • Smooth animation loop and modular component structure • YAML-based, backward compatible with existing setups

⸻

🔧 Planned features for the custom Lovelace card: • Easy UI-based entity configuration • Selection between W / kW display per sensor • Multiple layout backgrounds (e.g. with/without EV, battery, PV) • Multi-language support (English and German) • System-agnostic support: SIGENERGY, KOSTAL, and more • Available through HACS as a standalone custom card • Responsive layout for different screen sizes • Performance-optimized and easier to maintain

⸻

📌 The current implementation is heavily based on my own enhancements, but clearly inspired by your original YAML code. I intend to include a thank-you note crediting you as the original inspiration in the final repository.

If you’re okay with me developing a standalone card based on this, I’d appreciate your confirmation.

Any timeline or alpha version we can dig into ?

Thanks alot for all your effort in this @fbradyirl
My first ever project in HA and Yaml ;)
And would be lovely to see your work @H4TR1Z!
I have made SVG files exactly as Sigenergys moving in direction of the power. if you are interested in them?

Dont know how to make an fancy video/gif as you did :D
Link for moving flows.

Whole Yaml? or just the Svg files? i can share it all if needed :) If anyone just could show me where or HOW!? :P Not familiar with github

Yes the .yaml.

You can use the "code" tag in the github comment window. Or put it in pastebin.com lol.

Its a working progress.

Pastebin wont let me....
Using "code" will make the thread so long. so hopefully this works?

Hi All,

I hope its OK, instead of continuing to post in this Gist, I've created a new thread in the 'Discussion' section of the Sigenergy-Local-Modbus repository. Hopefully this will provide a central place for people to easily find this card and everyones efforts.

If people believe the card is maturing 'enough', I'll also see about posting it into the repository that TypQxQ has mentioned for consolidating card/addons etc, that will then allow people to easily FORK and start contributing to it with trackable merges/PULLS.

The Discussion Thread is at: TypQxQ/Sigenergy-Local-Modbus#184

Just a thought... there's also the Power Flow Plus card. It looks completely different from the Sigen app but I prefer it as it's simpler and clearer. Just letting people know there's options.

Hi everyone,
sorry for the delayed response. I’m currently on vacation, and development will start the week after next. Thanks for your patience!

Looking forward to the release!

any news on the update? thanks

should this grow into something better than just a gist? This is great!

Certainly looking forwards to this @H4TR1Z Thanks

Still nothing? I'm getting desperate.

Would you mind sharing your yaml again for the animation?
