Access Extension Module IO via Modbus TCP
I want to test out controlling the unipi via Modbus TCP.
Got accessing the Neuron working, but how do i access the Extension Modules?
I have 1 xS11 connected to the Neuron, how can i read it's inputs and set the relays?
I could only find the normal Modbus mapping of the xS11.
My guess would be that i have to offset them??
How does it work when adding a second Extension Module?

accessing the Unipi Extensions over ModbusTCP is not possible at the moment, although we are thinking about it.
You need to access the devices via ModbusRTU over the corresponding serial device. Here you can find the mapping of the physical RS485 ports: https://kb.unipi.technology/en:hw:02-neuron:portmap
