The current progress of study in PICNIC as a web-based actuator are accessing socket to getStatus and commanding lamps via web based. This code was written in PHP and using javascript for improving the button.

This is the page views of above code, I know that code above need to be check about the udp connection and how to supervise the lamp directly using socket connection.
