MQTT subscribe

[admin]

Add custom logic to the MQTT callbacks:

Code:

mclient.ON_CONNECT = function(res, ...)
  log('mqtt connect status', res, ...)

  if res then
    mclient:subscribe('100')
  else
    mclient:disconnect()
  end
end

mclient.ON_MESSAGE = function(mid, topic, payload)
  if topic == '100' then
    if payload == "C,1,1,\r\n" then
      grp.write('0/0/1', true)
    elseif payload == "C,1,0,\r\n" then
      grp.write('0/0/1', false)
    elseif payload == "C,2,1,\r\n" then
      grp.write('0/0/2', true)
    elseif payload == "C,2,0,\r\n" then
      grp.write('0/0/2', false)
    end
  end
end

Using one topic for controlling multiple entities is bad system design. Each relay should have it's own topic for control if possible.
