This is my first prototype for Home Automation.
ESP8266There are two buttons - ON/OFF.
Four relays, one door sensor and a reset button are connected to the Arduino UNO. All this is in the old PC case.
Two modules are connected to Raspberry Pi.
There is the BMP180 (for temperature, pressure); it's ready for DS18B20.
There is the MCP23008 module. There are one MCP23008, one level converter and eight input/outputs.
Arduino Mega is ESP8266.
