Try this driver, should work better for you: [DRIVER] Zooz ZEN Switches Advanced (and Dimmers)
EDIT: Actually my driver may not fix your issue, I think that parameter was removed by Zooz shortly after the first version came out a while ago, no idea why. I have brought it up but they never have said anything. Let me check my notes I will get back. I do not have that setting in my driver so you at least wont get the pending changes errors.
You are trying to get instant on/off when you control it via the hub correct?
