INSTEON: Troubleshooting Z-Wave Communications Errors

From Universal Devices, Inc. Wiki

In most cases, communication errors can be solved by either Healing the Network (Z-Wave | Tools | Heal Z-Wave Network) or adding additional range extenders.

Please note that once you change the location of any Z-Wave device, you must Heal the Network so that the routing tables are updated by the underlying Z-Wave algorithms. The link below provides more details as far as healing the network and range extenders specifically for door locks and other RF devices.
