I have just bought myself two Aeotec dual nano switches, which have 2 outputs (OUT1 and OUT2) and 2 inputs from two switches (S1 and S2). I think this applies to the non dual units too though (one out but 2 switches)
When paired with ST I see both outputs as devices - great - I can switch them through ST fine. But I can’t see the inputs from the external switches.
I know there is a parameter to change how the external switch(es) are handled - docs are incredibly opaque about what it does with regard to SPDT (L1 on switch connecting to S1) and DPDT switches (L1 to S1, L2 to S2) …avoiding 2 and 3 way as terms as they dont mean the same everywhere.
Anecdotal evidence suggests that a load on S1 turns on OUT1 and a load on S2 turns on S2 by default but there are options to
a) use a DPDT (and set parameter 121 to 3 way??) and I have seen posts that seem to say that the resultant S1 and S2 simultaneous change has a toggle effect on (both?) outputs, resolving the issue otherwise then you cannot turn the load on remotely and turn it off locally. I can’t see notes on this at all from Aeotec - any experience in this? and for dual switches?
b) it is possible to decouple the external switches from loads (parameter 122) - but where on earth does it announce to (in terms of ST devices/attributes)?
Does anyone have these and can explain how they work or is it just as obvious as S1 on, OUT1 on and vice versa?
[NB I would try to make a rig and test this with the 4 modes and a multimeter but I don’t have the bits and more importantly right now ZWave Tweaker isn’t working in the app, I am waiting in hope that the tiles finally appear in the device rather than the controls for the switch that relate to the default DTH - the settings page works for tweaker DTH but these tiles refuse to appear!!]
