Due to the long distance and a higher number of stations, I would like to control the valves via modbus. I already have Arduino boards ready that can be controlled via modbus. From the Raspberry I can switch them on and of via modbus. Now I would like to use modbus commands (which are python function calls) instead of GPIO pins. What would be the best way? The most clean way would be to write a plugin. But I am not sure if that would be appropriate here as it would influence a central part of the control architecture.
