I have a Schlage Z-Wave deadbolt paired to my v2 Smartthings hub. Recently the lock has been blowing through batteries and it will often show the lock as unavailable even though the lock touchpad works. I also have noticed that the hub is pinging the lock very frequently as well. The first set of batteries lasted about 9 months but now I get about 2-3 months per set.
What could be causing the increased battery use and instability and how can I fix the issue?
