[admin]

IIC Bus:

SDA:GPIO11
SCL:GPIO12

PCF8575/XL9555:U22 (output1-16): i2c address:0x25

PCF8575/XL9555:U17 (input1-16): i2c address:0x24

Note: after 2026-11-01 KinCony begin use XL9555 i2c extend chip. you can use KCS v3 "SYSTEM" webpage to scan device show the model or config by ESPHome to scan i2c bus, will find the chip model.
