Latest version has been moved to a new repo for pull request into official predbat: https://github.com/calvind80/batpred
It's possible to replace the existing ui in Predbat with this test version. Disable auto update then edit apps.yaml as follows
pred_bat:
auto_update: false
predbat_repository: calvind80/batpred #delete this row to go back to the main predbat branch
Once predbat restarts, choose the main version and once updated select Try the new interface in the menu. Use Classic interface to return; your browser remembers your choice. To remove it and go back to standard delete the predbat_repository line from apps.yaml and choose an official version.
Home battery prediction and automatic charging for Home Assistant supporting multiple inverters, including GivEnergy, Solis, Huawei, SolarEdge, SigEnergy, FoxESS, Sofar, Tesla Powerwall and many more.

If you find Home Assistant and Predbat too difficult to set up yourself, there is now PredBat Cloud, a paid version of Predbat hosted in the cloud. Please note that while I have given permission for PredBat Cloud to operate under license, PredBat will remain open source for personal use.
You can find the latest Predbat documentation at https://springfall2008.github.io/batpred/ and how-to videos on my YouTube channel.
The documentation covers how Predbat works and how to get it installed and configured, video tutorials and FAQs to help you get going. It also explains how you can contribute to the project.
