3-position momentary switches (3-wire, 2-way)



Problem 1:

I cannot figure out how to get the Fibaro Dimmer 2 to work a single 3-position momentary switch. These are circular dial switches where pressing toggles on/off and rotating left/right dims. ON/OFF works and DIMMING does not work.


Problem 2:

I cannot figure out how to get the Fibaro Dimmer 2 to work with a 3-wire, 2-way switch configuration. Whether each switch is a 2-position toggle switch, or a 3-position momentary switch, both switches need to be ON for the lights to be on. Absent the Fibaro Dimmer 2, the the lights toggle on by pressing either of the 2 momentary switches.




Each switch has 3 wires:


1 x Phase-1 Live (EU brown)

1 x Phase-2  (EU black)

1 x Phase-3 (EU gray)

0 x Neutral (EU blue)

0 x Ground (EU green/yellow)


For the lights to turn on, both switches Phase-1 AND Phase-3 need to be connected together. If either are disconnected, the lights are off.
