[Bestgear]

KC868-AI have 40 digital input ports. where you seen have 40 ports?
tasmota support MAX 32 channel GPIO, so you can use total 32 channels.
just download tasmota fimrware, enable PCF8574 function is ok.

I understand that the current Tasmota release binaries has support for four only of the  PCF8574P chips - Question - can I compile Tasmota for all six?

I understand that the limitation is by design due to potentially having duplicate IDs on the I2C bus - but I would be surprised if that is likely with six devices - what are your thoughts?

Thanks for your help.
