HA-Hub on Ulanzi D200X
After spending way too many evenings on this, I'm finally putting it in
the open: 
**HA Hub for UlanziDeck**
 — a plugin for the Ulanzi D200X
stream deck (the one with 14 LCD keys + 3 rotary encoders) that
integrates with Home Assistant via the WebSocket API.


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


Why I built it: I have an UlanziDeck on my desk, and the official
plugins for HA control are basic toggles. I wanted live state, real
encoder support, and the kind of fluid UX you'd expect from a deck
that costs €200.


**What's in it (eight action types):**


- 
**HA Toggle**
 — switches, lights, plugs, fans, covers, climate,
  media players. Custom on/off text. Pulse with configurable color.
- 
**HA Smart Toggle**
 — display state from one entity, tap toggles a
  different one. Useful for `binary_sensor.washer_running` +
  `input_boolean.deferrable_wm_forced` patterns.
- 
**HA Aggregate**
 — watch a list of entities, show "active count /
  total" on a single key, pulse when something is active.
- 
**HA Smart Dialer**
 (favorite feature) — universal encoder. Long-
  press any light/climate/cover/media_player/fan key for 700ms, the
  dial takes over and you adjust brightness/temp/volume directly. One
  encoder controls every variable entity in the house.
- HA Scene, HA Service Call, HA Sensor, HA Encoder for the obvious ones.




**Practical setup I'm running daily:**


- Aggregate key on home page watching four `binary_sensor.*` for EV /
  washing machine / dishwasher / aircon. Pulses orange when one is
  active.
- Folder right next to it with four Smart Toggles, one per device,
  with optional ⚡ FORCED badge for the `input_boolean.*_forced`
  override pattern.
- HA Toggle on my desk lamp. Long-press → Smart Dialer dims it. Press
  the dial = off.
- Scene keys for "work mode" and "deep focus" lighting.


**Status:**
 0.11.13-beta. Tested daily on my own setup with HA Core,
~3300 entities, Windows 11. Real-world testing on diverse setups is
the goal of the beta phase. License is AGPL-3.0 to match the Ulanzi
SDK.


**One catch:**
 Ulanzi's plugin SDK doesn't currently let plugins
navigate folders/pages programmatically. So an Aggregate key can't
auto-jump to its sub-folder when tapped — you use Studio's built-in
Folder feature next to it. I've sent a feature request to Ulanzi.


**CORS gotcha**
 worth flagging: for the in-PI "Test connection" button
to work, you need:


```yaml
http:
  cors_allowed_origins:
    - "null"
    - "file://"
```


The runtime WebSocket connection works without this — only the test
button needs it.


Issues, PRs, pattern ideas welcome. Especially curious about Smart
Dialer use cases I haven't thought of.

Kind regards,
