2x Relay without Wall Switch?

I’m looking to put a couple of the 2X relays into my system in places where I won’t have a manual wall switch (e.g. to control a pair of ball valves).

  1. To do that, do I just leave the S1 and S2 terminals open?
  2. How do I include the device in the system given that I won’t be manually able to turn on and off 3 times quickly?

thanks!

Yep.

2) How do I include the device in the system given that I won't be manually able to turn on and off 3 times quickly?

Most devices also have some kind of built-in inclusion button. The Fibaro ones, for instance, have a recessed switch which you can poke with a toothpick to include the switch in your Z-Wave network.

Thanks!
