Heal Network
Z-Wave is a mesh network, which means that if 2 Z-Wave devices want to talk to each other but they are too far apart to communicate directly, they will relay messages off other Z-Wave devices that are in-between. This means every device needs to know where it is in proximity to all the other devices, so it knows which devices it can use for relaying. This network map is created when you first add the device to your Z-Wave network. If you later move devices around, the map can be wrong, and the relaying might not work, so your Z-Wave devices may become unreliable.
To fix this, go to Devices on Vera's setup page, choose Z-Wave options, and Heal Network.
NOTE: This can take hours to complete. So it's best to let it run overnight.
This will go through all the devices one by one and have each device broadcast signals, and all the other devices around record those signals, and, in turn, the map gets rebuilt. At the same time, the 'device is configured' flags are reset, meaning Vera will attempt to re-configure your devices again. So the green 'device is configured' cog wheel icons (see: Device_Control_Status) will turn gray or blue as Vera re-configures the devices. Battery operated devices are normally sleeping and may not be configurable until the next time they wakeup, which can be several hours. So you may see some red cog wheel icons, which means Vera couldn't configure the device, for several hours.
After you've left the heal network run for a few hours, all the configure cog icons should be green again, and your network should work better. If you click the '+' icon next to each device, you will see a list of the 'neighbor nodes' for that device, which means a list of all the other Z-Wave nodes that are in close proximity.
