Hi,
I am using the Arduino Port Expander to get 8 Digital Outputs and 6 Analog Inputs.

# SCL is D1 and goes to Arduino's A5

# define the port expander hub, here we define one with id 'expander1',
# but you can define many

lambda: |-
auto expander = new ArduinoPortExpander(i2c_component, 0x08, true);
return {expander};
# define binary outputs, here we have 4, as the relays are inverse logic
# (a path to ground turns the relay ON), we defined the inverted: true
# option of ESPHome outputs.

Problem is, that after I activate the Analog Input Section, the Relais 3,4,7,8 are not working. If I comment out the Analog Sensor part, all 8 Relais are working fine.
I am using
D2 → D9 for the Relays
A0, A1, A2, A3, A6, A7 for the Analog Input
