/*
* This sketch demonstrates how to set up a simple HTTP-like server.
* The server will set a GPIO pin depending on the request
* http://server_ip/gpio/0 will set the GPIO2 low,
* http://server_ip/gpio/1 will set the GPIO2 high
* server_ip is the IP address of the ESP8266 module, will be
* printed to Serial when the module is connected.

in EventHelper.ModuleChangedHandler before you filter event for particular node. If you have three programs with this, then you see three output messages for one event.
