Does your incoming data really look like this without the opening curly braces?

Also if you parser.addString() you should make sure the original string is empty since when you already have a string stored that contains invalid data and add (aka append) to that you'll always ever see the old data and never parse the newly added.

Call function in loop

This would suggest the jsonParser has some issues validating the incoming data. In order to locate issues with your code one of the steps you always should take first is to add as many Serial.print() statements as you can to see what your code is internally doing and where it’s failing to do what you want. e.g. void myHandler(const char *event, const char *data) { bool b; Serial.printlnf("%s: %s", event, data); b = jsonParser.addString(data); Serial.printlnf("addString() ret…

Try reading out the JSON buffer via Serial.println(parser.getBuffer());

BTW, you are violating the 1/sec rate limit for Particle.publish() when the condition is satisfied.
