i'm triyng to add a pcf8574T via i2c but the kc868-a8 (I'm using esphome) doesn't see it during the scan. I checked the pcf with an Arduino Uno and everything works properly.
with Arduino I at first did a scan to find the right address. then i added the following code on the KC868-a8
#additional pcf8574t
- id: 'pcf8574_hub_in_2' # for input channel 9-16
address: 0x27
but I had no result
many thanks for your suggestion!
