home automation training -20-extend digital output & input in home assistant

1. extend output and input ports by hardware devicea. KC868-A series board  (integrate to home assistant by ESPHome)
   b. KC868-HxB series board (integrate to home assistant by MQTT)

   2. config ESPHome for KC868-A16

   esphome:
   name: kc868-a16
   platform: ESP32
   board: esp32dev

   # Example configuration entry for ESP32
   i2c:
   sda: 4
   scl: 5
   scan: true
   id: bus_a

   # Example configuration entry
   ethernet:
   type: LAN8720
   mdc_pin: GPIO23
   mdio_pin: GPIO18
   clk_mode: GPIO17_OUT
   phy_addr: 0

   # Optional manual IP

   static_ip: 192.168.1.199
   gateway: 192.168.1.1
   subnet: 255.255.255.0

   # Example configuration entry
   pcf8574:
   – id: ‘pcf8574_hub_out_1’  # for output channel 1-8
   address: 0x24

   – id: ‘pcf8574_hub_out_2’  # for output channel 9-16
   address: 0x25

   – id: ‘pcf8574_hub_in_1’  # for input channel 1-8
   address: 0x21

   – id: ‘pcf8574_hub_in_2’  # for input channel 9-16
