You got it.
To set the local broker in 10.10.10.1:1883 (mosquitto) you have just to set name and password on MQTT tab, if you also define a remote broker, topics will be defined local and remote at the same time. If you are on board connect to the local broker, if you are at home connect to the remote broker.
Looking forward to saying people RTFM but I am afraid first I should WTFM
