is the Z34 paired S2?
Edit... Either way, try these steps to do the firmware update (yes, they are very similar to the Leviton update steps I posted previously - basically the same process)... I don't have a Z34, but I have a bunch of other Zooz stuff and these steps have never failed me.
I don't know what the manual wakeup process is for the Z34, but its instructions should tell you.
