Zwave devices have disappeared after re-including a device in the zwave network

Configuration Z-Wave
1

Hello,

after installing hass.io, one of my zwave devices disappeared (a Fibaro smoke detector) from my Aeon Z stick.

i initially thought that the device battery was out so I changed it -> no luck.
I did try to include the device -> no luck
I did reset the smoke sensor and re-included it -> super bad luck…

All the zwave devices are now missing from Home Assistant and the zwave log is now showing me the following:

Could anyone give me a hint of what’s currently happening?

Is there a way to dump the list of devices registered on the stick (in order to check if there is any conflict)?

Any help will be greatly appreciated.

Your stick is no longer detected. If you can SSH in issue the following command: ls -al /dev/tty* | less see if ttyACM0 still shows up or if it may have been named ttyACM1.

@firstof9: Thanks! that was it. thanks.
I did use a different USB port when I plugged back the Z stick.

You can use ls /dev/serial/by-id/usb-* and add the device to your configuration.yaml in place of the /dev/ttyACM* That name will not change even plugging into a different port.
