After more than 15 days, the z-wave stick switched to offline.
I did not do anything special, appart perhaps installed a reboot-shutdown-switch following rpwong clear explanations.
I think that it stopped working when I rebooted the raspberry.
Option 1 and 2 are ticked on the raspberry config “prepare serial port” page; serial port of the stick is set to /dev/ACM0
Any idea of what could have happened ? And suggestion to solve my problem ?
Honestly, I am fed up with this Zwave stick problems …
