Earlier in this thread I mentioned someone made an integration of the SIA protocol in Home Assistant. So someone else forked this project and owns an AJAX alarm system: [https://github.com/eavanvalkenburg/sia](https://github.com/eavanvalkenburg/sia) The installation was quick and simple in Home Assistant. After that I made sure HA made URL calls to Homey when the alarm is on or off. In Homey I created a virtual alarm device to react on these calls. I now have a working on and off state in Homey. Very basic and simple, but at least I can now integrate the arm and disarm states of AJAX in my flows. ![Screenshot_20191126-233531_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/c/bc590d6bb1901bf9196dd39e14a318897789df54.jpeg) --- _[View the full topic](https://community.homey.app/t/ajax-systems-integration-to-complement-home-security/7558)._
