Hello,
I just published a new integration for Repsol Luz y Gas
See details here: GitHub - ad-ha/repsolluzygas-async: Repsol Luz y Gas Integration for Home Assistant
This integration is based on the one developed by @bzzoiro, but adapting it to be multicontract, multihome and incorporating async methods, UI configuration and adding new API sensors, aside form other improvements.
You can comment here on any questions or doubts. For technical issues and improvements, please post on Github.
Cheers
