How to set the output Fibaro Universal Binary Sensor

I’ve connected the Fibaro Universal Binary Sensor FGBS-0001 to Homey.
The inputs are working fine and I can use them in flows.
Now I want the output of this device to switch a relay.
How to do this? I cannot drag this device to the ‘then’ column!
Any suggestions?

Pitty. You are right. Why did I bought it?
Are there other devices that can switch a relay?

What voltage is the relay’s coil?
Anyway, you can use the Fibaro single or dual relay. Those units are a relay themselves.

Maybe i don’t understand so plz correct me if am wrong.
U can attach a relais to the output of the sensor. Only thing not possible is to set the relais on and off remotely. But for that u can attach something to the input.
Like Rob is doin with this very same sensor and the doorbell project.
Link is in Dutch btw.
