study the schematics of relay. the connections used for turning light ON/OFF works depends on the pin configuration of NC and NO. The light is ON when relay is at low state. Therefore in this case, NC (Normally close mode) is selected for turning ON/ OFF of light.

why we need variable "rly =0, or rly=1" 15:32
Madam kindly show the circuit diagram of the project
Bulb got ON momentarily before sms , in that case it may be problem for other device..
