Information on performing a full optimization of your Z-Wave Network
When first setting up your Z-Wave network, devices will not always readily recognize their neighbors to fill out the mesh network. The same can happen if you move a device from one location to another. Performing a full optimization on a device will help HS4 determine the best routes to get to your device and back to ensure proper communication speeds.
