Hello @sknobloch,
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

Hello @sknobloch,
if your program is some script or binary, you should use systemd for starting and keeping alive. This tutorial shows how to work with it: https://medium.com/@benmorel/creating-a-linux-service-with-systemd-611b5c8b91d6

Seems like the problem was a bad Connection or so.
Testet something else and had to reconnect the rs485 wires and now it works.
Bit weird that mbpoll worked without a problem...
