How to program a handler for a double switch (MCO Home)

@Cedric,

my device type for the Fibaro Dual Relay and corresponding button binder smartapp should work for you based on the zwave classes you posted. please try it, the biutton binder is needed to bind a virtual switch to trigger the second relay.

just copy and create the device type, & Smartapp and then add a new device in the IDE of type Simulated Switch, and then install the smartapp from you Apps and bind the virtual switch to your device
