led doesn't light up

[2sdaymars]

I bought it and used it, but it doesn't work.

I put the code on esphome and turned on the switch, but the led doesn't light up.

i use this code 


esphome:
  name: a16

  platform: ESP32

  board: esp32dev





# Example configuration entry for ESP32

i2c:

  sda: 4

  scl: 5

  scan: true

  id: bus_a



# 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

switch:

  - platform: gpio

    name: "light1"

    pin:

      pcf8574: pcf8574_hub_out_1

      # Use pin number 0

      number: 0

      # One of INPUT or OUTPUT

      mode: OUTPUT

      inverted: false



  - platform: gpio

    name: "light9"

    pin:

      pcf8574: pcf8574_hub_out_2

      # Use pin number 0

      number: 0

      # One of INPUT or OUTPUT

      mode: OUTPUT

      inverted: false

      mode: INPUT

      inverted: false



  - platform: gpio

    name: "input9"

    pin:

      pcf8574: pcf8574_hub_in_2

      # Use pin number 0

      number: 0

      # One of INPUT or OUTPUT

      mode: INPUT
      inverted: false

# Enable logging

do you have connect power with MOSFET output's terminal?
need connect with DC12V, every 8 channel MOSFET output use a common DC power supply input.  see "12/24V DC input" in photo.

thanks so much its work
is there no 16-channel Arduino coding?

[admin]

there are many arduino IDE demo source code, you can download at here: https://www.kincony.com/forum/forumdisplay.php?fid=25
[Arduino IDE demo source code for KC868-A16] series topic.

I am looking for a code to control 16 channel MOSFETs with Arduino mqtt communication~
i couldn't find

[admin]

you can modfiy with this demo source code: https://www.kincony.com/forum/showthread.php?tid=1843
this is KC868-A4 wifi work with MQTT, you just need add I2C code for mosfet output with A16.

THANKS YOU SO MUCH

you are welcome
