Yes, it is possible.
Goto your RF Bridge then click + to add a new remote:
Tick the Alarm at bottom then OK.
You will see a new Alarm item that you can rename, but press and hold to put the Bridge into learning mode.
Then press the RF button you want to use for this alarm.
Now go to create a Scene, + Add Scene.
+Add a Condition, that will be the Alarm you just created
+Add a Perform, that will be the device you want to turn ON or OFF
Finally Save the new Scene
When the RF button is pressed, the Scene will execute, and operate the device.
There is a bit of latency, no more than a second, about the time taken to press the button.
Of course, you will need to create another scene to turn back OFF or ON, this will use another Alarm.
You are limited to four Alarms only :-(
