MQTT subscribe

Check the latest log entry, it shows what data was published to the topic named "100". Modify the ON_MESSAGE callback function to execute actions based on the received payload:

Code:

mclient.ON_MESSAGE = function(mid, topic, payload)
  log('ON_MESSAGE ', topic, payload)
  if topic == '100' then
    if payload == "11" then
      grp.write('0/0/1', true)
    elseif payload == "10" then
      grp.write('0/0/1', false)
   end
  end
end

You can use MQTT explorer (http://mqtt-explorer.com/) to connect to LM and send any data to any topics to test your scripts.
