Would be great if xlights scheduler could do something like thisI use the Vixen SMS messaging system on a separate laptop to it's own matrix. I use xLights for the rest of the display. Geoff has done a great job of this software and is continually updating it
Works well and has a couple of great features built in like black and white lists which are editable and a built in scheduler to start and stop it.
It is by far the easiest way to do it and has plenty of support available right here.
You will be lucky enough to meet the developer in person at the Brisbane Mini as he lives in Ipswich and will 100% be there to answer your every question about it.
