Auf dem Master hab ich das hier ausgeführt:

root@rock64:~# iobroker setup custom
Type of objects DB [(f)ile, (c)ouch, (r)edis], default [file]: f
Host / Unix Socket of objects DB(file), default[127.0.0.1]:

Type of states DB [(f)file, (r)edis], default [file]: r

creating conf/iobroker.json
root@rock64:~# iobroker multihost enable
Miltihost activated.
Authentication activated.
Enter secret phrase for connection:
Repeat secret phrase for connection:
Server accept connections for objects on all IP addresses.
Please check the binding of redis service. By default it is only local: http://download.redis.io/redis-stable/redis.conf
Change "bind 127.0.0.1" to "bind 0.0.0.0" or to others.
Please restart ioBroker: "iobroker restart"


Miltihost:      enabled
Authentication: enabled
Objects:        file on 0.0.0.0
States:         redis on 0.0.0.0
root@rock64:~# sudo service iobroker restart
root@rock64:~# sudo service redis-server restart

Zusätzlich hab ich die redis.conf editiert und das bind 0.0.0.0 eingefügt.

Auf dem Slave hab ich

 sudo iobroker setup custom
Type of objects DB [(f)ile, (c)ouch, (r)edis], default [file]: f
Host / Unix Socket of objects DB(file), default[127.0.0.1]: 192.168.1.190

Port of states DB (redis), default[6379]:
Host name of this machine [ubntcontrol]: ubntcontrol
creating conf/iobroker.json
pi@ubntcontrol:~ $ iobroker multihost connect

Nach dem multihost connect kommt dann leider

events.js:183
      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRNOTAVAIL 192.168.1.190:9001

Hab ich irgendwas falsch konfiguriert ?

Auf dem Slave laufen noch Adapter. Muss ich die erst löschen damit es läuft ?
Der Fehler sieht eher nach was anderem aus.
