Re: File /wo2x flows/Kenwood CAT to relay example.json
Dave, WO2X
OK
I removed the TCP Request Node and routed the Inject Node to the HEX to string Converter node. Test that with a simulated KENWOOD serial frequency command string <FA00007150000> and it outputs the desired relay command. in the DEBUG window...So far so good
Next I replace the INJECT node with a Serial-In Node. After the proper baud rates(4800-N-8-1), etc the node registers "Connected". I take the serial cable from a known working connection ( Radio to Stepp-IR controller) and attach it to the USB serial connection on the R-PI. My USB/Serial dongle has a series of LED's in it that allow to me monitor activity. When the frequency is changed the RXD line flickers with activity so I am pretty sure traffic is flowing in to the serial in node but apparently nothing coming out to the HEX/String converter
What did I miss??

If you need to share Kenwood CAT with other programs then you can take the Kenwood CAT payload and send back to a PC.
Think of Node Red as a flow chart. Input data, pass it to next node, do something with dat, pass it along, do something, etc.
Do Google searches for example Node Red flows, especially for Home Automation. They will give you an idea on how Node Red works. It is very easy once you start playing around. There are plenty of flows in the file section which will give ideas on how to accomplish a number of things.

I finally found a good beginners tutorial <Workshops.opto22.com> which helped me a lot. Though I usually dislike U-Boob videos this kid's Midwest accent was flat enough and his voice had enough bass for my 160M static damaged ears to understand
Thanks again as this sounds exactly what I was going to try and do

Double click on the Antenna Button, you want to changes. ?Revise the "Label" as shown below.
Some other buttons have an in-line configuration function for the labels, but not so in this case.

Re: QST Magazine Sept 2021
Thanks! We should be seeing new users as some get QST and get interested in Node Red.?
I was working this afternoon on integration of the 4O3A OM module into the 2x8 antenna switch flow. Since there are MANY different configurations of the OM module use I will not be publishing it on the file section but anyone who wants it, just ask. I customized it for a ham with a 30 meter array where he has East, Omni, and West as three profiles on the OM switch. It allows selecting the profile from Node Red and sets the button for active profile to green when he is on the band that uses the array. When on other bands all buttons are grey.?

Re: Backing up Flows (and the entire RPI)
I would recommend attaching secondary storage and then using to manage backups of the system to that.? It will make good use of the space?and will give you not only the ability?to restore from a catastrophic failure but also from more subtle failures (corruption over time, accidentally blowing up a config, etc) far more easily.? It's fast, supports a lot of backend options, and will minimize the load on the device when actually doing the backups.
You don't have to do local storage though.? You could also set up?something like Minio on your windows machine and use that for the backend.? Just local storage will usually be faster than over the network.

Re: Backing up Flows (and the entire RPI)
Mike,
I've been using a script for years to do this. I find just making a clone of the running Pi is more convenient as it ends up making a run-able SD card in the process. All you need is a USB adapter with the target SD card in it. Make all the incremental copies you want, and you never have to shut down the Pi to do it.
You run it from a shell prompt, so no VNC / GUI required.
It's not my work, but can vouch for it's abilities.
Get the script from here:
OR, from the Pi shell prompt, just install it like this:
git clone
cd rpi-clone
sudo cp rpi-clone rpi-clone-setup /usr/local/sbin
For instance, after you stick the USB adapter it the Pi, run dmsg to see the last few lines of the system log. You should see the USB device was mounted on one of the serial devices, sda, sdb, etc. Mine usually show up as sda, so:
sudo rpi-clone sda
In a few minutes, you have a bootable clone of your running SD card, cloned to the SD card in the USB adapter.
Read the readme for rpi-clone so see how it supports systems that are booting from Jump drives too.
