                  Did you edit the /etc/owfs.conf file? It should contain the following:

                  !server: server = 127.0.0.1:4304
                  allow_other
                  server: port = 127.0.0.1:4304
                  server: i2c=ALL:ALL
                  timeout_volatile = 2
                  

                  You will need to restart owserver for these settings to have effect. Or reboot the Raspberry Pi.

                  Can you post here the output of the owdir command? Please start with only 1 expansion module.

                  Jaroslav
