WLED

[danborge]

Hi,

Has anyone done a WLED integration? Tried searching the forums (and google), without luck. My goal is to use KNX+ LM visualization to control WLED (on/off, dim, color, effects).

I've also tried looking at other json scripts, but its quite difficult to understand with zero lua scripting knowledge...
The WLED page on json isn't very helpful (https://kno.wled.ge/interfaces/json-api/)

WLED also support MQTT (https://kno.wled.ge/interfaces/mqtt/), but that was even more difficult to understand

I have developed a pretty good library if you want. It just controls one segment though, but you can adapt it a little to control more than one

Thanks, that would be great  Got one segment on two different ESP32s, so its just what I'm looking for.

Example for brightness control.

Attach an event script to 0..100% scale object. Change WLED_IP to your WLED device IP address.

Code:

http = require('socket.http')
json = require('json')
ltn12 = require('ltn12')

url = 'http://WLED_IP/json/state'

value = event.getvalue()

data = json.encode({
  on = value > 0,
  bri = math.round(value * 2.55),
})

res, code = http.request({
  url = url,
  method = 'POST',
  headers = {
    ['content-type']  = 'application/json',
    ['content-length'] = #data,
  },
  source = ltn12.source.string(data),
})

log(res, code)

Thanks, I'll make a script and try this
