Notice: This port runs per default using uid:gid domoticz:domoticz to avoid security problems. Some code of Domoticz may needs root access. If you are ok with that change the following rc.conf to: domoticz_user="root" domoticz_group="wheel" And restart domoticz. If you have issues with domoticz listen option, you can add net.inet6.ip6.v6only=0 to /etc/sysctl.conf If your install is a new one, a default user has been created : User/Password: admin/domoticz Please modify password ASAP in menu Setup -> MyProfile
