//trigger next event.
handler.postDelayed(runnable, SAMPLE_INTERVAL_MS);
private Runnable runnable = new Runnable() {
//this class deals with generating periodic events,

johnty / ESP8266-hue-sensor.ino
Created April 2, 2016 03:28
Arduino ESP8266 sketch for updating the status of a generic CLIP status sensor. hardcoded AP/password and Hue IP/API strings.
/**
Custom ESP8266 CLIP sensor for Philips Hue system
GPIO2's high/low state will emit two different status values
which can then be used to trigger Hue bridge events
You will need:
0.) Wifi network and Philips Hue bridge connected to it and set up, with an API key
1.) A custome IP sensor (CLIP) created in the Hue bridge
2.) A rule hooking up the status of the IP sensor and events we want
