My Setup:
PC, Windows 10, openHAB designer (working well with OH1 under Windows)
Raspberry 3, openhabian, OH2, Samba (everything working well)
On my Windows PC I can access the directory /etc/openhab2/ on my Raspi as a Samba share (shared as “openHAB-conf”) which I mapped as windows drive letter “O:”
I can read and write all configuration files in all subdirectories on my Raspi with a Windows text editor like notepad++ , for example edit files in O:\persistence or O:\sitemaps .
But if I try in my openHAB Designer under Windows to set O:\ as the configuration root, I get the error: “The choosen directory is not a valid openHAB configuration directory.”
