In the Z-Wave Node View for a battery powered device I see a button labeled “Wakeup” which I guess is a Device Command to wake the device up.  Where I’m not clear is to the right is a box “Interval” along with a Drop Down for the units of time.  The wakeup interval is configurable using a Parameter.  Does pressing the “Wakeup” button simply send a wakeup command to the controller or does it overwrite the Parameter in the controller with the values contained in the boxes to the right of the button?

That's device specific. You'll need to refer to your device others manual usually going on their website.

 

Yea, I was doing a little reading on the Z-Wave protocol, the WAKE_UP Command Class allows a battery powered device to notify another device that's it awake... not necessarily a "wake up" command to bring the device to life.  It looks like it is just used to set the WAKE_UP_INTERVAL, the time between Wake Up periods.  Looks like maybe Command Class, version 3 introduces the capability to request a wake up on demand, but the node has to support it too.  I don't know if ISY supports Command Class version 3 and I can't find any detailed specs on the device.  So, more reading & experimentation and consideration of getting the Silicone Labs Dev. Kit.  Finding the time to learn a new protocol is what is difficult.
