Lesson20 - extend hardware digital output and input channels in home assistant - admin - 04-27-2022
1. extend output and input ports by hardware device
a. 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
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
address: 0x22
# Individual outputs
