Detecting button press on Fibaro without connected load

Hi all,
One of my Fibaro dimmers (v2) does not have a load attached, but I would like to know if someone pushes the button. Is there a way to do this?
Thanks!

The Dimmer2 needs a load during the auto-calibration process. The best approach is to use the Fibaro Bypass 2 as the the load (and leave it permanently connected). Alternatively, use one of the Fibaro relays, they don't require a load (but do require neutral).

You can then monitor S1 and/or S2 states; alternatively activate scene control.
