RE: Installing Node-Red on a Raspberry Pi
No pressure for tomorrow morning then.....(grin)! If you ever want a sample of one of my flows, they are easy to download and the upload into another Node-Red machine. I use this process to backup my flows

RE: Installing Node-Red on a Raspberry Pi
In my opinion, Node-Red is a GUI for node.js. It allows you to easily generate complex programs with a simple to use and understand User Interface. I don't know node.js and when I look at the code I've

RE: Installing Node-Red on a Raspberry Pi
Great question! It's built on node.js but it also has the flow editor that allows you to build the software by joining the pieces of the flow. In their words "Node-Red provides a browser based flow

I'm not talking to it yet, I was hoping someone might find the pi software they had used to decipher the serial data coming from the controller (hint, hint, grin!)! I was able to connect my laptop into
