Devices no longer reachable

[gelessor]

I have lost connectivity with about 10 z wave units (both lights and plugs). They suddenly lost control and when i tried to re-optimize I'm getting a message that they are not reachable. If I move them closer to the Z-Stick I can regain control. If this is a "mesh" network I don't understand why this is happening. I have about 70 total z wave devices throughout the house and before this problem occurred they all showed at least 5 or 6 "neighbors".

Is there a new plugin I should be using for HS4? Up until about a week ago this thing was rock solid. I'm at a loss as to what to check. Any help is appreciated..

When this sudden loss of communications happens it's typically caused by either a device that has gone bad and flooding the network, or bad routes in the routing tables from an optimization. Try only optimizing the devices that aren't working and test.

How do you optimize a device that is unreachable?

As usual... Rupp was right!

i had a couple devices go bad that were flooding the network. Life is now good again
