Using 2 x PCF8574 with esphome

Hi,
I am try to set up esphome to use two pcf8574 devices. I have the model that can be connected one to eachother, If I load on esp32 a scan i2c code with arduino I can see both devices on addresses 0x20 and 0x24 (i changed address on the second one).
I2c bus is wired on 21/22 on esp32.
However I can t manage esphome to see and use both of them,
This is my code

captive_portal:

i2c:
   - id: bus_a
     sda: 21
     scl: 22
     scan: True

pcf8574:
  - id: 'pcf8574_hub_0'
    address: 0x20
    pcf8575: false
    i2c_id: bus_a

  - id: 'pcf8574_hub_1'
    address: 0x24
    pcf8575: false
    i2c_id: bus_a

switch:
  - platform: gpio
    name: "relay_01"
    pin:
      pcf8574: pcf8574_hub_0
      number: 0
      mode:
        output: true
    inverted: false
  - platform: gpio
    name: "relay_02"
    pin:
      pcf8574: pcf8574_hub_0
      number: 1
      mode:
        output: true
    inverted: false
.......

and this is the log after load the code

Seems it can t see both pcf and also get that error communicating with pcf…
Any idea what I am doing wrong ?

Thank you very much
