gweempose Posted January 27, 2017 Posted January 27, 2017 It is my understanding that when you use the "Heal Z-Wave Network" command, the system automatically maps out the most reliable routing for each device on your network. Is this correct, and if so, is it recommended to perform this operation each time you add a new device?
mwester Posted January 27, 2017 Posted January 27, 2017 Yes*, and yes**. *note: battery-powered z-wave devices go to sleep, and do not usually respond to any network-initiated actions such as "heal" -- thus, if you wish your battery-powered z-wave devices to participate in the "heal" operation, you'll usually need to dash off to each while the "heal" is running and do "the right thing" (which depends on each device - check the manual for the device) to wake it up so that it responds and participates in the process. **note: the frequency used by z-wave is shared and often in close proximity to other devices that can interfere -- so you may find it useful to run a "heal" not only when you add a new device, but also whenever you move or introduce any OTHER 900-MHz devices (which can include baby monitors, wireless intercoms, etc, etc).

Thanks! The only battery-powered z-wave devices I currently own are some Schlage BE469 locks. I could be wrong, but I believe these are capable of being "woken up" by a controller or other z-wave device.

Because of this I would have thought it was unwise to have battery powered devices included in the heal. If a battery powered device is part of a route for a Z-Wave device and it doesn't wake up to forward a message then that message would fail. Better to let the heal complete without interference.

You are right, the locks are capable of being woken up and are processed by the route discovery process/"healing". "Battery-operated slaves that do not listen continually are disregarded by controllers when they calculate routes." http://zwaveworld.com/2011/all-z-wave-articles/ask-the-expert/may-23-2011/ So, there should be no danger that the controller will choose a battery operated device as a repeater.
