UniPi 1.1 communicates with external Rpi
I wonder if anyone ever tried to build up a communication between a unipi and a raspberry pi?
As I have a lack of digital ins on my unipi I would like to use the raspberry's GPIOs to forward a switch action to the unipi.
I already have two unipis which communicate over sscp, but I have no idea if and how this can be done with the raspberry.

if you use Mervis on UniPi 1.1, then you have practically no other option other than to use ModbusTCP. On the RaspberryPi you can create a Python script utilizing the pymodbus library and program the logic in a way the DIs and ROs are mapped to the coils and AO/AI are mapped to registers.
