If a Z-Wave device dies for some reason, there is a facility in the Z-Wave controller to “remove failed node” which will remove the dead node from the controller.
I don’t see that ST has the ability to run this command.
The Repair Network just goes around and does a network rediscovery which is fine if all the nodes are still there (and maybe they’ve moved around a bit so the routing tables need to be updated). Repair Network is a good thing and with 500 series Z-Wave chip controller in the hub (in the V2 hub) it will be really important to do on a regular basis.
A dead node in a Mesh network is bad because the routing algorithms will keep trying and keep trying all the different ways to get to the dead node. But its dead so it will never respond.
As a result, the entire Z-Wave network appears to be flakey to the user because there will be this huge lag at times while the controller is busy trying all possible ways to get to that dead node. When it finally gives up, then the other commands will get thru but until then the user keeps pressing the button and nothing happens ARRRGGGHHHH.
The only solution I see now is to reset the hub and re-join all the nodes to eliminate the dead node… VERY BAD…
@duncan - any insight here?
