MQTT text string?
I have a device (ESP32) that is sending data to signalk MQTT broker,
for values (eg /vessels/self/electrical/generator/Oil/pressure ) which works fine.
however Im also trying to send a text string which is the generator status (eg “Running”)
when using MQTT tool (or similar) to look at messages on MQTT server, … i see two entries , the second of which is reported as NaN
(& in signalk data browser it reports as null)
It looks like MQTT is ok with me sending simple values, but it doesnt like a string?
Am i correct that i need to do some specific formatting in the MQTT.publish( ) message?
