Triple click on switch to add Fibaro Dimmer 2?

Is it possible to triple click on switch to add my connected Fibaro dimmer 2 in Homey (as I did when I added all my dimmer 2, in Fibaro HC) or do I need to open the wall socket, pull out the dimmer and press the B-button?

Of course is it possible to use the switch button instead of the B-button to include the Dimmer 2.
But make sure Homey is in close proximity to the dimmer. You can use an extension cord, for example.

Thanks, Now it’s working. Needed to keep Homey very close to the switch
