I Just have installed Openhab, i have had a lot of systems but all of them had problems, mainly using with Google (voice)
I have finally installed Zwave but the system had 4 ports and i had installed 4 times Zwave before i got zwave online. How to throw away the wrong devices? The trash gives a dialog and the only thing rest is cancel Too bad you can not edit just one device,
Zwave serial controller online
Zwave serial controller Offline communication error
Zwave serial controller offline bridge ofline
Zwave serial controller offline bridge offline

Very strange that you can not re edit a device so when you got the wrong usb device (4 times) you must re add again the controller. Also the trash icon is not working.
Where do i find the switches?
