Hi need to send message through internet when valves turn on and off. The setup is:
I have a OSPI system and trying to use stations as HTTP
On the other side I have an arduino with a ethernet (5100) shield waiting for those messages (when station goes on and off).
After that I simply send messages by modbud (the arduino is simply an interface for me to receive messages from ospi and redirect actions by modbus)
I have some experinence (not much) with arduino but perfect newbie with ospi.
