Guys, you made my day!
I have a z-wave network with 26 nodes (Fibaro switches, plugs, smoke detectors, motion sensors… on a Aeotec gen 5 stick.
Every now and then it became unstable and two range extender (I bought to improve the signal strength) went dead.
Healing, pinging restarting did not help.
So i thought I need to re-include them (?).
Then I tried your usb cable truck with a cable laying around and voilà!
After a restart of the Zwave integration both dead notes came back to life.
I hope that this will have fixed the issue.
Thank you so much for this thread
