Multiple power failures, schlage z-wave lock now says "this device is unavailable"

Hi, Just tracking the problem and resolution here to help others in the future.

A power line got pulled down in my vicinity recently. After multiple resultant AC and Internet downtimes over the past couple days as they installed new poles and cables, then had to tension them correctly, my Schlage Camelot lock is showing as unavailable.

So this evening I’m going to restart the ST hub. Pull the power, pull the batteries, and let it boot fresh.
If that does not work, I will remove the lock from the door and bring it closer to the hub and repeat the process.
If that does not work… suggestions?

Problem solved.

Removed batteries and power from Hub, left alone 1/2 hour, re-powered. Didn’t work.
Took batteries out of lock. Re-inserted batteries.
