I have a problem with PCB8574 in the type of INPUT. My code was validated and uploaded to the ESP8266. i2c working, the address of module is visible, but there is no reaction to the change state of the GPIO.

Please do these two things:

  • Use the latest dev image of ESPHome (contains a small fix) - see FAQ
  • Enable VERY_VERBOSE logs - see logger page

Thanks!

I installed the latest version ESPHome 1.13.0-dev and enabled the log level VERY_VERBOSE. After upgrade the outputs also stopped working.

I noticed that if ESP8266 is loaded without the connected PCF8574, and then on the hot connect PCF8574, then it works!

I ran into the same issue after upgrading to 1.13/1.13.1. Unfortunately I can only log remotely and the VV logs are discarded before I can read them.

@IvanHorban how have you been able to hot connect the pcf8574? At what moment do you connect it?

It seems a matter of initialisation order: on 1.12 I see i2c logging before pcf8574, on 1.13 it is the other way around.
