Run mqtt locally?

[Sailoog]

@Sailoog - does this work the other way round? Can you send a mqtt message from a signalk value in openplotter? I use node-red but if you could send from inside openplotter it might help anyone to monitor away from the boat without having to get into node-red.

Yes you can.

Set a general MQTT topic "xxx" and create an action "Publish on topic: xxx", press "Add Signal K key" button and select the key you want to be published.

There is another way using the signal k plugin "signalk-mqtt-gw" on signal k app store but I have not played with it yet.
