Battery Entity

Setup requires only a few lines of YAML with clear required (type, entity) and optional fields (name, warning, critical), as shown in the README example usage.

Users can set warning and critical levels (defaults at 35% and 15%) to tailor battery level indicators, allowing personalized monitoring for different devices.

The card uses color-coded icons that change to yellow for warning and red for critical levels, providing at-a-glance battery health monitoring directly on the dashboard.

It focuses on minimalism with a single JavaScript file, seamlessly integrating into existing Lovelace dashboards without heavy dependencies or complex setups.
