I have installed Openhab 3 on a Raspberry Pi and can connect to a Philips Hue and Unifi system successfully.
I then connected the Pi via a USB to Serial adapter to my Niko PC-Link module 05-200. As far as I can tell (but I have never done this under linux, only on Windows) the device seems connected properly (checked with lsusb, and dmesg tells me ‘pl2303 converter now attached to ttyUSB0’), the openhab user has rw access to /dev/ttyUSB0’ (courtesy of being in group ‘dialout’), and stty of the device tells me ‘speed 9600 baud; line = 0; -brkint -imaxbel’ (which I think is correct??).
I then installed the Nikobus add-on, but when adding a PC-Link thing the status goes from ‘uninitialized’ to ‘unknown’ and I do not know how to troubleshoot further.
Can somebody point me in the right direction ? How can I for example check if the serial settings are indeed ‘Baudrate: 9600/no parity/no handshaking/Number of bits: 8/stopbit: 1’ ?
