Do I need to Exclude and re-Include a device when changing its battery?
Short answer is No, you do not need to re-Include a device after changing its battery.
Sometimes we've found that some users will inadvertently reset a device while replacing the battery thus stopping all Z-Wave communications.
We show how this can accidently happen here.
Under normal circumstances you don’t need to do anything else other than replacing the batteries.
Keep in mind though it could take a couple of minutes for the sensor to stabilize and start reporting back on the Z-Wave Network.
