By the virtue of blooming automation industry and wireless connectivity,all the devices within the home,college,offices and so on can be connected.This improves the comfort,energy efficiency,indoor security,cost savings..In such case,power usage and network bandwidth become a major question.We need a low capacity device that transmits messages through a less vebose protocol.Owing to the ubiquitous availability of wifi, all the appliances with in a region can be commonly connected.This paper presents an overview of a prototype,attempt to implement MQTT on ESP8266, a wifi based development board.Realys are connected to ESP8266, a wifi based development board.Realys are connected to ESP8266 MQTT broker is established for remote control.
