[Plugin] HA Hub — Home Assistant integration for UlanziDeck D200X

weemaba

Hi all,

I'd like to share a plugin I've been building for the UlanziDeck D200X:
**HA Hub** — a Home Assistant integration that turns the deck into a
control surface for smart-home devices.

GitHub: https://github.com/weemaba999/ha-hub-ulanzi

## What it does

- Live state on every key, no polling — pulls from HA's WebSocket API
- 8 action types: Toggle, Smart Toggle, Aggregate, Scene, Service Call,
  Sensor, Encoder, Smart Dialer
- Pulse animations with configurable color and speed
- Long-press any light/climate/cover to enter Edit Mode, then turn the
  Smart Dialer encoder to adjust brightness/temperature/volume
- HA logo reveal animation when switching pages (per-tile or experimental
  puzzle reveal across all keys)
- Test connection button gives instant ✓ / ✖ feedback
- Global URL + token — configure once, all keys inherit

## Status

This is a 0.11.13-beta. I'm running it daily on my own setup with HA
Core and ~3300 entities. Worked through about 20 SDK quirks during
development (some documented in CONTRIBUTING.md for future plugin
authors).

## Feature request to Ulanzi

The one limitation I ran into is that plugins can't programmatically
navigate folders or pages. I've sent a feature request to
ustudioservice@ulanzi.com for a `$UD.switchPage()` or
`$UD.openFolder()` API. Would unlock a much richer UX category. If
others would benefit, please second the request.

## Try it out

Download the latest release zip from
https://github.com/weemaba999/ha-hub-ulanzi/releases and extract the
`com.ulanzi.hahub.ulanziPlugin` folder into:

- Windows: `%APPDATA%\Ulanzi\UlanziDeck\Plugins\`
- macOS: `~/Library/Application Support/Ulanzi/UlanziDeck/Plugins/`

Restart Studio, drag any HA Hub action onto a key, and follow the README
for first-time setup.

Issues, feedback, PRs welcome on GitHub. Built on the Ulanzi Plugin SDK
v2.1.2 — full AGPL-3.0 license.
