I want to use the Fibaro Universal Binary Sensor as an alarm sensor in the Heimdall app but Heimdall does not see the Binary sensor.  
I think that’s because the Binary Sensor is not set as an alarm sensor is the settings.  
How can i change that or how can I set de binary sensor in a way that Heimdall can work wit is?

Use a Virtual Device with the Fibaro Universal Binary sensor: [Heimdall - Let Homey watch over your home](https://community.homey.app/t/heimdall-let-homey-watch-over-your-home/134/8)

Hi Danee,  
Ok, I saw that option.  
I assume I have the set the VD via a flow based on the actions of the Binary Sensor.  
But what values should the VD get, open/close or true/false?

PS, thanks for the quick reply.  
Regards,  
Jan
