Our V2 and S2 switches introduce new types of wiring methods for multi-point control set ups that haven't been seen before among Z-Wave devices. For the S2 switches in particular, you can now add this model to a 3-way configuration without re-wiring the second box, and you can use S2 switches in 4-ways and 5-ways where load and line are separated between two boxes. You can even wire them in 6-ways and 7-ways provided that line and neutral are in one of the boxes.
But as a result you can only use regular 3-way on/off switches in your multi-point control set ups. That means no regular switches with LED indicators either - this is because the "dumb" switch (regular on/off) in the 3-way only gets an electronic signal through its neutral; it doesn't actually receive any power. The LED indicators on these switches require power to light up, so it may pose problems with the installation.
The switches should always be wired exactly as shown in the diagrams, following all specifications in the manual. You can find out more about wiring your V2 switch here, and your S2 switch here. In the meantime, we'll continue to work to find a solution that allows Zooz switches to be used with another electronic switch.
