Zwave problem

[ulf_slask]

Hi
I have installed and added a lot of units to my domoticz installation. The problem is that I can't control them now. I get this message
Error sending switch command, check device/hardware !


I have restarted the system and unplugged the USB stick but nothing helps.
What can I do?
