Some Z-Wave devices (including the Aeon Labs 4-in-1 Multisensor, but there may well be others) do not update properly when the open z wave option to verify value updates is set to true. From my research it is unclear whether this is a bug in open z wave or the actual devices, but for these devices to work properly with openzwave, SetChangeVerified must be set to false. Since for many devices verifying changes is a desirable behavior, I propose adding an option to verify changes globally as part of the node module config.
Here's an example from a log file showing the problem:

Basically, for this particular sensor the initial read of the temperature is correct, but all of these attempts initiated by the controller to verify that value fail, and this generates A never-ending stream of traffic to attempt to verify the value.
