Hello,
I have several wireless radiator valves around the house that I have had intermittently working with the FHT binding and CUL transport. Getting the CUL transport to work was very hit and miss. Sometimes it would start correctly, other times it would output the “can’t open CUL” error but checking the log would show that the binding was, in fact, working. Other times it would simple not work. Yesterday I rebooted the Ubuntu 16.10 VM that OpenHAB is running in and since then it has been impossible to get the CUL transport to work.
I have OpenHAB 1.8.3 running in an Ubuntu 16.10 amd64 VM on ESXi 6 build 4510822. The CUL device is a CC1101-USB-Lite 868MHz (CULv3) from busware.de and it appears in the VM as /dev/ttyACM0. I’ve added the openhab user to dialout group. The config in openhab.cfg is:
fs20:device=serial:/dev/ttyACM0
fs20:baudrate=38400
fs20:parity=NONE
fht:housecode=6178
fht:device=serial:/dev/ttyACM0
fht:baudrate=38400
fht:parity=NONE
Connecting to the CULv3 using screen with the command “sudo screen /dev/ttyACM0 38400” showed it receiving data.
I’ve installed the latest snapshot version of the CUL transport and FHT and FS20 addons from cloudbees:

The error I always see in the logs is:

I’ve read other posts that state that the problem has been solved either by running OpenHAB as root or by installing a newer version of the serial transport. However, I can’t find how to run OpenHAB as root in Ubuntu nor can I find a later version of the serial transport.
Can anyone suggest how I can fix the above error?
Thanks,
Steve.
