Fluvy – a free, open-source theme + 39-card library for Home Assistant (light and dark, 15 palettes, live demo)
I've been building Fluvy for a few months and it's out on HACS: a theme and a card library for Home Assistant designed as one thing. The theme (light and dark, fifteen palettes or your own accent), thirty-nine cards, Activity and History pages, a settings panel and an automatic dashboard, all drawn from the same design tokens. GPL-3.0, no telemetry, no network calls of its own.
Live demo, the real cards and settings panel on a simulated home (change palette, mode, device and language and watch them apply live): https://acosta290.github.io/fluvy
GitHub: https://github.com/acosta290/fluvy
What's in it:
• Every card has an editor form and a live preview in the card picker; unavailable, unknown and missing states are drawn on purpose, never as an error.
• Sliders and dials are precision controls: relative drag, slide away from the ruler to slow down, hold for the 1 % scale.
• While HA wears the theme, its own pages (Settings, Devices, Automations, dialogs) follow the same design.
• Activity and History pages in the same idiom, with a switch to get HA's own pages back.
• An automatic dashboard: one line of YAML and it reads your areas, devices and energy preferences.
• Seven languages: English, Spanish, German, Dutch, French, Italian and Brazilian Portuguese.
Install: HACS → Custom repositories → https://github.com/acosta290/fluvy as Integration → download → restart → Settings → Add integration → Fluvy. It's in the queue for the default HACS store.
