Is a professional alarm possible?

I described how to couple a Jablotron alarm to Homey in this post: Commercial Home Alarm System that I can use sensors from? - #6 by zigvespa

It does not work with a Jablotron app, but you have to add Fibaro Binary output mudules to the Jablotron system. This allows the Fibaro app to read the state of your alarm system and use this in flows (e.g. blink all Hue lights when the alarm goes off).
