Z-Health™ is an exclusive HomeSeer Z-Wave feature designed to keep your Z-Wave network operating at its peak. Consider the benefits of network optimization, but done automatically while you sleep. If you are planning frequent changes to your network, if you move items in your house around often which can change the RF characteristics of your house, or if plug-in modules are found frequently unplugged in your home, then Z-Health™ may help.
If enabled, between the hours you specify, HomeSeer will optimize one node at a time, repeatedly, until the end time is reached or the entire network is successfully optimized four times. Four successful optimizations result in old routing information being completely cleared out of nodes and replaced with new or current routing information.
During the Z-Health™ optimizations, other Z-Wave functions may be delayed slightly. Detailed status messages about the nodes being optimized are displayed unless the "Suppress Z-Health™ Optimize Messages" option is checked. When the Z-Health™ operation is complete, statistics about the nodes in your system are displayed. If HomeSeer has been running for more than one iteration of Z-Health™, then statistics since the last time HomeSeer was started will be displayed.
A node that is on the "fringe" of your Z-Wave network, which means that it has occasional communication problems because there are no nodes near it, then optimization of that node CAN result in all communication with that node being severed if the optimize procedure is done at a time when the node cannot reach any other nodes or the HomeSeer Z-Wave interface. Z-Health™ should not be enabled unless you have a fully meshed network or are aware of no such communication issues like this.
If a node is not a "listening" node, which means it does not always have its radio turned on to hear Z-Wave signals, then it cannot be optimized, and Z-Health™ will skip those nodes. This typically applies to battery operated devices which turn on their radio only at certain times for short periods of time. Since these devices are not listening all the time, they do not typically participate in routing, so optimizing these types of nodes typically benefit only the node itself, and not the entire network. To optimize nodes like this, go to the device properties page for the node, wake up the node using whatever method is available as per the manufacturer's instructions, and then click the Optimize button to optimize just that node.
