Suggestion: companion Lovelace card for EcoFlow devices

Hi! Thanks for the excellent ha-ef-ble integration — it works great with River 3 / Delta devices.

I’ve made a lightweight Lovelace card that fits EcoFlow power stations particularly well:

Noema Power Card

• Animated liquid battery sphere + neon LED bars
• Charging / discharging flow indicator (uses input/output power sensors)
• Neumorphic buttons & vertical toggles for AC/DC ports
• Sliders for charge limit / AC charge speed
• Optional SVG history graphs
• Visual GUI editor, zero dependencies, single JS file
• EN / RU localization (follows HA language)

Example for River 3 (entities from ha-ef-ble):
