A network rediscovery is a Z-Wave command that determines the optimal routing path for Z-Wave commands based on the network layout. A common cause of Z-Wave network communication issues is a lack of repeating nodes between the Z-Wave controller and the affected Z-Wave node.

A good solution is to add repeating nodes between the Z-Wave controller and the Z-Wave node experiencing communication issues. However, because Z-Wave networks are designed to be static, network rediscoveries must be run to re-determine optimal routing paths to Z-Wave nodes when devices are added, deleted, or even moved on a Z-Wave network.

Note: For information about selected device network rediscovery (i.e., single node rediscovery), see Selected Device Rediscovery.

Two types of network rediscoveries are used: non-wiping rediscoveries and wiping rediscoveries.

Types of Network Rediscoveries

Non-wiping rediscovery

Non-wiping rediscovery commands are the more commonly used rediscovery command. Unlike the wiping rediscovery, a non-wiping rediscovery does not erase and recreate the Z-Wave network routing table; it merely looks for new routing paths to add onto the network.

This is the type of rediscovery to run after adding, moving, or deleting a Z-Wave node from the network. It is also the type of rediscovery that is performed by a panel that is capable of network rediscoveries.

Wiping rediscovery

Wiping rediscovery commands, which are only available with Z-Wave firmware older than the Lock OTA firmware, completely erase and recreate the Z-Wave network's routing table. It is generally used while troubleshooting (e.g., if a Z-Wave device is within range of other repeating nodes).
