Home assistant server status LED

Configuration
1

Hi, I just recently build my HA Server, designed and 3D printed a case for it, and added a D1 mini with LED ring running WLED inside the enclosure.

I want to use that D1 mini to “show the status” of my HA server, like this
(I have the “scenarios” i want in presets in WLED)

If nothing happens the Led ring just fades and comes back
If HA Discovers a new device or needs an update (notification) then switch to the notification preset until i do what’s necessary
If there’s an error, Solid red preset
When i do something like turn a light on or off, or if an automation starts, the i want a small “loading” bar
ETC…

I didn’t find anything online, so I’m asking for your help here, if someone can help me.

See Pictures…

Welcome!

Could you use the Home Assistant WLED Integration? Then you can use Automations to do what you want.

So, i tried making an automation, and i’m stuck with 2 things.

First i have to select a trigger device, when what i want is “if any device changes state”

and second, there’s no preset scroll down menu for changing presets in “lights” action

If you have any suggestions

PS: maybe something that can be done with yaml code, but i’m not in the mood for that, and i’ll need some documentation and examples

I do all my automations in Node-Red so I can’t help you with yaml or the native Home Assistant automations stuff (that’s why I provided the automations link / documentation above). Hopefully, someone else can jump in and help).

Hey @StefanRosu1999 — welcome! :wave:
Your idea with the LED ring inside the HA server is awesome — and you’re really close to getting everything working just the way you want.

If you’re feeling limited by the UI (e.g. not being able to trigger on “anything” or set a preset directly), I’d recommend checking out my custom integration:
:link: WLED Live View Proxy for Home Assistant

It adds a service that lets you send raw JSON API commands directly to your WLED device over WebSocket — so you can:

  • Change presets by ID :white_check_mark:
  • Trigger from any event (like state_changed) :white_check_mark:
  • Send loading effects or dynamic progress indicators :white_check_mark:

Here’s a quick example to activate preset number 4:

action: wled_liveviewproxy.send_command
data:
  targets:
    entity_id: light.wled_ring
  command: {"ps": 4}

And here’s how you can create a dynamic progress bar using the Percent effect — for example, based on device status or battery level:

action: wled_liveviewproxy.send_command
data:
  targets:
    entity_id: light.wled_ring
  command: {on: true, seg: [{id: 0, fx: 98, col: ["00ff00", "000000"], bri: 255, ix: "{{ states('sensor.battery_level') | int(0) }}"}]}

:bulb: You can replace sensor.battery_level with any numeric state — like signal strength, disk usage, open/close percentage, etc.

No need to mess with dropdowns or REST formatting — just clean direct control.
