MQTT publish json

[JohnTH]

Hi,

I am using admin`s mqtt script from this post: https://forum.logicmachine.net/showthread.php?tid=1759

Is there a way to change this:

  object_to_mqtt = {
    ['1/1/1'] = 'out/topic1',
    ['1/1/2'] = 'out/topic2',
  }
 
to send a variable that is a json string with multiple values (something like this):

valueX= grp.getvalue('32/3/1')
valueY= grp.getvalue('32/3/2')
topic1 = '{"site": "building", "equipment":"ventilation3601", "current_mode":"'..valueX..'", "current_status":"'..valueY..'"}'

  object_to_mqtt = {
    [topic1] = 'out/topic1',
    ['1/1/2'] = 'out/topic2',
  }
