I have recently installed an Aeotec ZW111 Nano Dimmer. Two (dumb) hardware switches are connected to inputs S1 and S2 of the Aeotec. S1 is being used to dimm a light hard-wired to the module. That part works fine, after setting up association groups I get proper status updates in openHAB.
Via the second input (S2) I would like to fire a rule in openHAB. Trouble is, after setting up the association groups and fiddling with a lot of parameters I still don’t get unambiguous returns for the two switches.
The first one (S1) returns a dimming value via the ‘Dimmer’ channel. In addition on/off is sent via the ‘Switch’ channel. The related channel is shown as deprecated but working nonetheless. The second switch (S2), however, returns only a dimming value which is either 0 or 100 depending on switch position. I already tried changing parameters 123 and 124 (determining whether the inputs control the hard-wired load or only the associated nodes) to no avail. The switch controlling the load always sends dimming value and on/off status, the other one sends dimming values 0 or 100. With those returns it seems impossible to write a rule which is only triggered by the S2 switch.
I am wondering, has anybody used this module for a similar purpose and made it work? Any ideas on how to work around this issue?
