How to build a web controlled home automation center.
This post describes the software used with the miniature router (OpenWrt), the PIC 16F628 lab board, the serial communication and radio protocol.
Lab board to connect almost anything to the web.
This low cost solution uses a 3$ PIC16F628 microprocessor and a 15$ OpenWRT router.

You don’t need to cut a hole in your router to mount an extra connector for serial communication.
Use the existing micro USB conector instead! (This example uses a TP-link WR703N running OpenWRT)
