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:

  - id: 'pcf8574_hub_out_2'  # for output channel 9-16

    address: 0x25



  - id: 'pcf8574_hub_in_1'  # for input channel 1-8
