Hi Mike.
Haven't? used it myself, but have you considered node-red-contrib-string ?
?

I have a workable solution
(Dave, no driving and texting)? :)
Take the string and convert it to csv.? I can manage the rest.??
But, I will like to see your idea.

Re: INA-219 Node Fixed/Updated, no longer requires downgrade to Node.js v10
Thanks Neal. I am going to spend some time updating the Groups.io site tomorrow including fixing the order of FRStack install in the WiKi.?
There are other node updates I have noticed also.?

Summary:??This node WILL NOT install if your system is using Node.js v12.x or higher.
So if you did a fresh install of a raspberry pi OS in 2020 or later, you will need to roll back

Re: Getting started with Node Red
Thanks for the feedback Fred. ? I have to admit, I do not know JS. Everything I have done in Node Red I have been able to figure out or learn from Google searches and loading example flows from different sites I found using Google. ? It is really a 3 step process in creating a flow: - Getting the data into Node Red
- Manipulating the data into format for viewing
- Laying out the dashboard to display data
? There are tutorials on using the Raspberry OS via telnet (terminal) and/or VNC or local desktop to Pi (monitor keyboard and mouse connected to Pi). I’ll try to ferret out a good video and provide a link. ? I think the next Zoom session we could work on building a couple of flows. One for getting and sending info to a device and another for controlling simple relays. I actually saw a video online the other day where the author used 3 relays to create a traffic light system. It was very good in explaining how to wire things up. ? 73 Dave wo2x ? ?

Alan, Dave ... thanks for the Zoom meeting last night. I appreciate your taking the time to host that.?
I have a very extensive? multi-state remote radio system in place and have been remoting since the 1990's. As automated as I am, I often have to bring up multiple systems. There is an appealing elegance to the Node Red dashboards I'd seen.? I was attracted to Node-Red for the control simplicity it offered.
I had a steep learning curve over the past few days to get where I am on Node-Red. I have done a lot of work with Arduino and C++, but I've never played with an OS, the RPi or JavaScript. In future lessons, you might help others along by realizing that there are really 4 steps to mastering this for someone like me (an RF engineer):
1. Learn how to run the Rasberry Pi itself. How to interface to a terminal, etc.?
2. How to load and run the OS.?
3. Learn how to load simple flows in Node-Red using GPIO interfaces.?
4. Learn programming in JavaScript and building the dashboard.
Most Node-Red "beginner" tutorials assume you already know steps 1,2, and 4. That was not the case for me. I felt there was a lack of mid-level tutorials out there. For example, I could find little about how to build and arrange a dashboard. Your meeting last night filled that gap and got me heading in the right direction.?
That said, sometimes the only way to drink from a fire hose is to start drinking.
Thanks for making yourselves available to true beginners and for your patience.?

we can receive the UDP broadcasts from our various Ham apps and use the results

functions to build the command to display the "Name>Call Sign" as a spot on

TX frequency, until I look up a new call or when I trigger the "remove all

your own connector to extract Name and Call from other popular Logging
Applications.? I am sure Dave and/I could help/write the adapters....just
ask. Here is a screenshot of my Maestro's Panadapter. Alan.
