take a photo, maybe you have not connect power wire with Vin terminal. see this diagram, all RED "12v/24v DC Input" should be connected.

what's your I2C address used in ESPHome config yaml? i think you need to use new i2c bus address will solve your problem, see here details:

FYI
I changed back I2C address 0x24,0x24,0x21,0x22 , now All my Input are working as expected like before.
But Output 2,3,5,6,7 and 8 not working other outputs are working as expected
