Z Wave Stick (S2) dying?

Hi,

at my father's system, suddenly I get "waiting for Z-Wave Interface"; when I try to send a command, everything hangs, interface gets lost (Z-Wave with red bar bottom left) and nothing works; then it reconnects for few minutes, and then again.
Unplug/Plug nothing changed
Reboot nothing changed

Stick dying?
Which is the best way to replace? AFAIK no backup available, only chance to exclude/include again everything?

Thanks

Sounds to me like the stick may be dying. If you can't back up and restore the data, then the best bet is to exclude/include the devices into the new stick. You won't have to redo all of your Indigo stuff; just assign the new node ID to the existing device definition. Best practice is to do one (or a few) at a time so you don't lose track of which device is which.

I replaced the extension USB cable and now it works

Nice find. Glad you were able to find a simple solution.
