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.
Web controlled home automation
Web access lab board (internet of things)
Lab board to connect almost anything to the web.
This low cost solution uses a 3$ PIC16F628 microprocessor and a 15$ OpenWRT router.

Access serial communication on a mini router (no extra connector)
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)
Using a Sony Ericsson dock as an USB2Serial adapter
Getting serial connection (5v RS232) from a USB SEMC DSS-20 SyncStation.
Guide for: Disassembly, Attaching serial communication cables, Remove serial EEPROM to avoid custom drivers for the FTDI232 chip.
