The code explores MQTT library (Thanks! Tuan PM), JSON APIs (Thanks! Jan Penninkhof). Code can be extended for devices such as build status monitoring etc. Anyways the code is available at <url>https://github.com/anupak/esp8266-samplecode/tree/master/mqtt_alarm_clock</url>. Description is in the blog post <url>http://forgetfullbrain.blogspot.in/2015/09/mqtt-experiment-solving-real-world.html</url>.
Feedback is welcome.
