Firmware to be loaded to WiFi Bee ESP v1.0 module (DFROBOT) ESP8266 chipset using Arduino IDE.
Relay board TOSR-04 (TinySine) will be used with default preset firmware (protocol) in its ATMEL MEGA328P chipset.
Implemented HTTP server with buttons for manual relay control.
URI = "/FF" + relay number + command.
Relay numbers: 00 = all ; 01 = 1st ; 02 = 2nd ; 03 = 3rd ; 04 = 4th.
Commands: 00 = turn off ; 01 = turn on ; 02 = swap state.
Swap all is not supported.
Example command: http://1.1.1.1/FF0101
