This looks lovely, but I wonder about the reliability for anything that touches living things.
I set up an Arduino-based programmable logic controller to manage the fogging and primary heating circuits for our commercial greenhouse, with a separate Node.js-based server component that handles only Arduino configuration changes, logging and alerting and it works beautifully. The idea of having a full Linux machine (especially in a RPi form factor) running the process control functions would be a bit scary.
Still, the capabilities here seem so far beyond what you could do with a single PLC that it's very impressive and I can definitely imagine using it for something non-critical, or with multiple hardware backup systems.
To be fair, the description at the top is really generic and the "Uses" section that clarifies it is buried pretty far down. Looks like a very cool project.
So it's like modbus but for raspberrys (both computationally and literally). It's really cool. I always wanted to do this to a small herb garden or tomatoes.
