The official and supported way is to use a bypass 2 as a load. Install the dimmer in 3-wire setup. Live to L, N to Neutral, bypass lead 1 to output, lead 2 to Neutral. Connect the switches. Power the circuit... wait 20-30 seconds until the indicator flashes green. Include the device as usual. I used this setup to make an association from my dimmer S1 (group 2 = basic set) to a Fibaro Double Relay output 2.
