#11558 im not sure if outside world cant send data to your esp module without opening a public port.

what you can do maybe is ask esp to get data from a webservice.
for example, a latest status of your sensors pushed to thingspeak can be pulled in by the esp.
even the latest tweets in your tweeter account can be pulled in to by your esp module.

can you post your scenario here?
