One thing to keep in mind is that battery powered Z-Wave units cannot provide you any information until something actually happens (or they come up one of their, fairly widely spaced, wakeup intervals.) So, if you cycle the automation system for some reason, you can't get any information from the sensor. It could be a number of hours using the typically configured default wakeup period before the automation system can see the state of the sensor, or unless it changes state before then and reports that state change.

So if it was already in 'run away or die' state when the automation system comes up, you won't know that. Or if you need the temperature info it provides in some logic, or other thing like that, then that logic will fair or do the wrong thing until such time.

That's a particular annoying thing about Z-Wave battery powered devices.
