I am on a rPi2 with a Razberry and having the same problem even after installing build #694. On the offline and the online build I get bundle:list | grep serial
175 | Active | 80 | 3.12.0.OH | nrjavaserial
(where I was expecting to see something like 3.9.x from comments above) and the error persists:
Controller is offline to OFFLINE (COMMUNICATION_ERROR): Serial Error: Port /dev/ttyAMA0 does not exist.
(Note on rPi2 the Razberry is /dev/ttyAMA0).
The apt-get install is still Build #688 so I will do an update and try there.
I have made other comments on Zwave Binding Uninstalls[SOLVED] and Razberry is Offline
Thanks to all those who have posted so we have had things to try with this issue.
