Hello Homey’s I’m looking for a new alarm system and want to connect it to homey, if not i use homey itself. I know you can use Homey as a alarm system with Heimdall and sensors. Is there anyone that uses homey for alarm system and do you recommend it? Pros and Cons? ---

Hello Andre ! Yes I’m using Homey, Lifx bulb, Sonos and sensors as alarm 🙂 First I’ve “Trigger” flows with motion sensor and “open/close” doors sensor: ![27](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/b/b65bb2dba3f03b8743d4bcf3ae54314aeb176dde.png) When triggered, this flow launch the “Alarm scene” flow. This flow manage flows to activate and disable after x minutes. He also notify me via notification: ![28](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/9/92e926d7d132fcb42dc2ca03d05b1ab526d65a1a.png) Finally I have alarmSound and alarmLight flows: ![18](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/b/b0d04533a0ebf5b5a1ec4c88aa7e7db3a791b582.png) ![14](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/9/999819357552863943b367f9ef2d4cc36a1ee8a9.png) I’ve also my IP Cam who start recording on my synology when I leave my apartment. ![07](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/5/5aaf269e6255fa4bd10aff507c2a36349b17b83b.png) Hope it helps ! ---

Thanks Julien for the quick reply i already new that is was posseple, but it was cool to here that someone actually use it. i like the idea that i chose what is happening when the alarm is triggered. do you only use geofencing for arm / disarm? ---

Thank you Ted. my plan was to use Heimdall, but that fully automated geofencing arm /disarm is actually pretty cool. i will buy some motion and door/window sensors Thanks for the help guys. ---
