Hi,
Testing both lcd 2004 and 1602. This is the issue : the 2004 does’nt work and the 1602 do .
I’m working with ESP32 Wroom.
The code :

i2c:
  sda: 21
  scl: 22
  scan: true

display:
  - platform: lcd_pcf8574
    dimensions: 20x4
    address: 0x27
    lambda: |-
      it.print("Hello");
      it.printf(0,1,"%.1f",id(temp).state);

Result :

esp2002-1602

I’ve used the same components with the same ESP+micropython for years without any problem.

ideas, advice?

Thanks a lot !
