Do you have the serial package installed --> org.openhab.io.transport.serial-1.8.2.jar?

Did you add openhab to dialout group -> sudo usermod -a -G dialout openhab

What is the error on you logs?

@zeblong

for me I had to put -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB0\ right at the begining for it to work at usr/share/openhab/bin/openhab.sh - i removed from /etc/init.d/openhab it did not make a difference. below is how it looks for me. also check the output if dmesg for changes in tty. I also use jessie on a RPi3

Thank worked with change to openhab.sh - I had to put -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB0 at the begining to be able to work. I'm not sure why it would workthere and not on the /etc/init.d/openhab. Also there is not start.sh when you install using apt-get it is named opendhab.sh

Thanks!!

@ted said:

-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0

I tried that but it did not work - this is how part of the /etc/init.d/openhab looks - any other ideas - i did not needed this with the RPi2 and wheezy

I recently moved my OpenHab install from a Raspberry PI 2 to a Raspberry Pi 3 from wheezy to jessie and now the biding is not working. Everything was working perfectly with the previous install now i keep getting the following message, serial port exist and it works. I suspect it has do to with the change from wheezy to jessie but nothing i tries is working.
