Publishing a topic in JSON Format

[David Tschank]

Dear developer,

I'm using the MQTT Dash app and i enjoy it very much. Im currently trying to publish a topic in the JSON format but it doesnt seem to work. do you have an example for me which i can use?

Im trying to use a dimmer and my device expects a JSON in the format below:

/my/topic/

{

  "state": "ON",

  "brightness": 10

}

How can i do it with the MQTT Dash app.

Thank you in advance

Best regards

David

on Receive

if (!event.data) { event.data = {}; }
event.data['obj'] = JSON.parse(event.payload);

on Tap

event.preventDefault = true;
if (event.data['obj']) {
 s=event.data['obj'].state=='ON';
 event.data['obj'].state=s?'OFF':'ON';
 app.publish('/wrt/butt', JSON.stringify(event.data['obj']), false, 1);
}

mosquitto_sub -h  host -t /my/topic/
{"state":"OFF","brightness":10}
{"state":"ON","brightness":10}
{"state":"OFF","brightness":10}
{"state":"ON","brightness":10}
