So I know konnected.io has just launched a service with noon for monitored alarms, however if you are outside of the US, or Noon’s service this doesnt help.
What you could use is a simple Rpi to act as the decoder. Its a cheap way to integrate and has been working perfectly for me for a while now.
You can see the thread here on how to do it: DSC -> EVL-3(4) -> Alarmserver -> Smartthings in case noon isnt an option for you (like it wasnt for me)
