Understanding Z-Wave Network Rediscovery
A network rediscovery is a Z-Wave command that determines the optimal routing path for Z-Wave communication based on the layout of a network. It helps resolve issues caused by devices being moved, added, or deleted within a Z-Wave system.
One of the most common causes of communication issues in Z-Wave networks is a lack of repeating nodes between the controller and the affected device. Adding additional repeating devices—such as powered light switches, plugs, or thermostats—can help strengthen network reliability. After doing so, a rediscovery must be performed to update the routing paths.
Tip: For information on rediscovering a single device, see Selected Device Rediscovery.
Types of Network Rediscoveries
Non-Wiping Rediscovery
The non-wiping rediscovery is the most common type and does not erase existing routing information. Instead, it updates the network by adding new communication paths while preserving existing ones.
- Recommended after adding, moving, or deleting Z-Wave devices.
- Helps maintain stable communication without disrupting the current network.
- Supported by most panels capable of Z-Wave rediscoveries.
Wiping Rediscovery
A wiping rediscovery completely erases and rebuilds the Z-Wave network’s routing table. This command is available only on older Z-Wave firmware (pre-Lock OTA updates) and is primarily used for troubleshooting severe communication issues.
- Clears all existing routing paths and re-creates the network map from scratch.
- Can be useful if devices within range are still experiencing connectivity problems.
- May take longer to complete and temporarily affect connected devices during the rebuild.
