Raspberry Pi Codesys Project

Paul,

I am definitely interested in your efforts regarding using Codesys at home. I have worked for the past 25 years in the real-time manufacturing control systems field. I have used multiple platforms, including Beckhoff’s Twincat PLC software and their I/O. This is the first I had heard of Codesys be able to run on a Raspberry Pi. Very cool!

As far as network connectivity to SmartThings, there are two basic methods.

  1. LAN connected device that communicates through the ST Hub.
  2. LAN device that connects directly to the ST Cloud via an OAUTH enabled SmartApp.

I have a project that implements the first method above when using an Arduino or ESP8266 based board. You may find some of the network source code useful for your project. My ST_Anything project allows bi-directional monitoring and control of the I/O pins on the Arduino/ESP8266 boards. In case you’re not familiar with the ESP8266 platform, you can buy a NodeMCU v1.0 ESP8266-12e board for under $10 on Amazon (under $5 on eBay from China). This little board provides 9 digital pins (input or output) and 1 analog input pin, along with built-in WiFi.

Good luck in your project and please keep us posted in this forum as you make progress.
