All Schlage lock Offline at same time

You may want to do a Z-Wave repair. Usually if one device in the chain is offline it should automatically pick a different route. A Z-Wave repair can help fix those routing issues.

This is the device handler @milandjurovic71 is referring to (which can access advanced features for Schlage locks and also fixed a few bugs in the locks firmware which can cause loss of information while communicating with the hub).
