1. PCF8574 GPIO can't use for send IR signal. i have told you set the IIC bus frequency is for testing IR, now it confirmed, can't use by PCF8574 GPIO, if you want to use A32 send IR signal, chose a free GPIO for ESP32, then you can have a testing. i don't know your IR sender module circuit, maybe it only need a ESP32 GPIO connect to it directly.
2. you can test short digital input with GND for trigger, if it's ok in ESPHome. i think you can set the PIR, usually open it, have a "NC" or "NO" jumper. maybe you need to change it, just let it dry contact output, chose "NO".
