MQTT Client app

[myg]

UPD: i moved all my rules to the new application (54 total) hope it won't break anything :-D

so regarding throttle, the following approach seems to be working, with the knowledge that i should use unique names per each script

"In" event:

Code:

ls_bedroom_throttle = ls_bedroom_throttle or require('user.mqttclient_common').throttle(60)

local data = json.pdecode(payload)
if type(data) == 'table' then
  return ls_bedroom_throttle(data.illuminance)
end

user library:

Code:

return {
  throttle = function(timeout)
    local last_update = 0
    return function(val)
      if(val ~= nil) then
        local now = os.time()
        if((now - last_update) < timeout) then
          return nil
        else
          last_update = now
          return val
        end
      end
    end
  end
}

SUGGESTION: 
1) in error log make it obvious which script contains error, so i can fix it easily. For example this error does not have information where to look:

error: failed to run script - [string "in-26"]:9: attempt to compare nil with number

2) output errors in global error log so they can be noticed in time
