I need to add WLED comms from a Crestron Lighting Control System. Because of the limits of the Crestron programming environment I need to use a simple method. My needs are to turn a strip On and Off with a fade initially, then add one global color and in a perfect world set each pixel to a specific color. I think UDP or sACN would be the easiest.
Anyone done this?
No, never tried that actually 
Does the Crestron environment have any means to trigger an http request?
Alternatively (an perhaps a little more convoluted) can Crestron communicate with something like a garage door to open it?
If you can get Crestron to trigger a relay, you can use that to connect to a GPIO and fire a preset.
Can open UDP and TCP sockets and then send data as ASCII or Hex. I can talk sACN to DMX controllers successfully but nothing I do works for WLED sACN. By default, with sACN I use port 5568 but have been unable to confirm that port works with WLED.
Disclaimer: I haven’t done any e1.31/sACN/DMX work myself.
It may be worth a look at the KB notes: WLED-E1.31 if you haven’t already. There’s a discussion about sender priorities that may have some impact on your setup
As far as the port goes, I do note if you try and set the Network DMX input type to “Custom Port” (Config->Sync Setup->Realtime), it defaults to 5568, which is a fair sign that’s where it listens.

I had good luck using the HTTP API integrating with my Elan (Nortek, now Nice) controller. I’m not at all familiar with how Crestron is programmed, but if it has a module to just send HTTP requests, it will work.
HTTP API here…
Great feedback. We have a large sACN library from other projects so I need to give this one more go but will shift to HTTP API if I can’t make it work. I think my controller died, so on hold to get a replacement.
TY!
