zwave operations question

[jkmonroe]

so im still learning about how zwave actually works. i came across this in a forum and it got me to thinking -

I feel silly writing that last sentence because of course it should work that way!
However, that's not how the Leviton VRCS4-MRZ works when I go through the Hub.
Pressing a button the first time sends an "on" command, the second time sends an
"off" command, on, then off, on, then off, and so on. It doesn't matter if the switch is
off, it will still send an "off" command. If the Hub would just toggle the switch when I press
the button, then there would be no need for two-way communication. But as it stands,
the VRCS4-MRZ needs feedback in order to send the correct command.

so let's see if i get this right, please correct me where im wrong:

right now a scene controller sends out a scene actuator message, which we can receive no problem in CQC. but when we go to turn the scene off, it always sends the same message.

assuming my understanding of the above is correct, if the VRC0P sees the incoming button press and then sends back some data that we'd have to extrapolate as acknowledgement, we would then see an identifiable 'OFF' message?

so for a scene controller - button 1 sends command identifiable as button 1, VRC0P receives command, driver then sends back acknowledgement that 'scene' was actuated and button light stays on. press button again to turn off, but this time the message would be different, so the scene knows to turn itself off. VRC0P receives message, driver sends back acknowledgement and button light turns off.

does that make sense?
