I don't define pins in this sketch, this is intentional. I only send "on" or "off" to 7 sensors at regular intervals... To prove that the HC2 and Z-Uno can "understand each other", but only if I remove both checkmarks in S and M column, save, and then add M checkmark!

If you want an example of "reading a digital pin" and you are new to Arduino I can recommend the examples on the Z-Uno site. See:

https://z-uno.z-wave.me/examples/SimpleSensor/

Thanks for your support!
Finally I've got 5 input sensors and 2 switches with zuno by this sketch
Also I had to change param 12 into value =1 and switch to MultiChannel associations mode any of zuno devices (obviously it takes into MC mode all the rest zuno devices automatically).

But leakage sensor I got on pin 7 instead 12 (as defined in sketch)

actually, based on my experience I might say that Z-uno is black box (on current firmware I hope) IMHO

UPD: two switchBinary channels aren't works with mentioned sketch
