Re: Challenges while installing the LP700 Flow in Nodered 4.0 with node.js version 20.xx and npm version 10.8.2 and workarounds

RocketNJ@... (Dave wo2x) — Fri, 23 May 2025 10:13:14 -0700

Thanks for this!

I am going to test it here. I have been using Virtual Here to forward the USB ports for the LP700 and Shack Master 600 power supply to my operating position PC. Then use the native apps for each.

Just need to carve out time to play.

Thanks Vinod for the contribution and instructions. Yes, Stoptimer 2 will work in place of Stoptimer 3.

Vinod,

Thank you so much for the guidance for the Node-Red LP-500/700 installation guidance. I recently built a new Node Red 4.0 server and delayed putting it into production due to issues with the LP-500/700 flow. Your guidance was spot on. Thanks again!

KMTronic Panel

va3mw@... (Michael Walker) — Thu, 22 May 2025 18:11:10 -0700

Hi All

I have always wanted to tidy up my KMTronic 8 relay web relay so it takes up less space.

I wanted 1 button that had the name in it and the button to be GREEN when on and GREY when off. GREY seemed better than RED.

I also started using some global variables, so you only have to set the IP address in 1 place and not 8 places! :)

Now, with this, you just have to edit the name in the UI TEMPLATE - the Turquois button.

I will upload the flow to the files section.

73, Mike va3mw

Thank you Mick

Node would not download yesterday using either the pallet manager or command line

I successfully downloaded this morning using pallet manager without having to reinstall Node-Red

Appreciate your help

The OpenWeather node is located here in the flow...

You will probably need to install the node from the pallet manager

Once installed you will need to create a account and get an api key. I also see you are getting a not found when trying to install from the cmd line. I checked the npm registry and the node is there..

If you can't load it from the pallet manger, then your node red install has issues. You may have to reload node-red.

I am having a problem locating the openweatherMap Node module which I need to run your weather flow

Can you point me in the right direction??

HamLib and Node Red

A really good video on how to install HamLib on a Raspberry Pi and use a standard set of commands no matter what device you plug in.

If you missed my Node Red at Hamvention, here it is: https://www.youtube.com/live/4pyNZPshXZ0?t=19943s

We did something a bit different for this forum. I didn't want to run through the slides that I've presented over and over so we tried a LIVE demo. Which is always dangerous. LOL.

We connected my KX3 to a Raspberry Pi and controlled it via Node Red.

Re: How To : ser2net - Serial to Network Media Converter with a Raspberry Pi

kylekrieg@... (Kyle AA0Z) — Tue, 20 May 2025 05:58:04 -0700

Sorry for the delay here. Hamvention has delayed everything as I'm just getting back into the swing of things. The CP2102N should be included in the kernel. Not sure why it's not showing up. I don't think it matters but have you tried another USB port on the Pi?

I control my WA4MCM switches with no issues. We are using Triplite USB hubs and plug 3 of them into that.

Once you get it working I'd be interested to hear what the issue was.

Doing some more research I'm thinking I need to install the USB driver for the Silicon Labs CP2102N onto my nodered RaspPi. I downloaded the linux driver and have these instructions. I'm not sure which instructions to follow ubuntu or Redhat? Or perhaps there is a single line command I can enter similar to the single line command I entered to install Ser2Net?

I think Ubuntu step #1 is to execute the file Makefile. An executable came with the download of the driver called Makefile. At least I think it is an executable file.

Makefile content:

obj-m = cp210x.o
KDIR = /lib/modules/`uname -r`/build
SRCDIR = $(PWD)
# try this instead if you don't have PWD defined
# SRCDIR = $(shell dirname $(realpath $(lastword $(MAKEFILE_LIST))))
all:
$(MAKE) -C $(KDIR) M=$(SRCDIR) modules
clean:
$(MAKE) -C $(KDIR) M=$(SRCDIR) clean

Build instructions:

Ubuntu:
1. make ( your cp210x driver )
2. cp cp210x.ko to /lib/modules/<kernel-version>/kernel/drivers/usb/serial
3. insmod /lib/modules/<kernel-version/kernel/drivers/usb/serial/usbserial.ko
4. insmod cp210x.ko

RedHat:
1. yum update kernel* //need to update the kernel first otherwise your header won't match
2. yum install kernel-devel kernel-headers //get the devel and header packages.
3. reboot //your build link should be fixed after your system come back
4. make ( your cp210x driver ) // should be able to build successfully at this point
5. cp cp210x.ko to /lib/modules/<kernel-version>/kernel/drivers/usb/serial
6. insmod /lib/modules/<kernel-version/kernel/drivers/usb/serial/usbserial.ko
6. insmod cp210x.ko
7. sudo chmod 666 /dev/ttyUSB0
8. sudo chmod 666 /dev/ttyUSB1

Thanks Giorgio for suggesting an alternative method. From what I've seen so far I believe it should be possible to communicate with the WA4MCM RAAS-8 via the Rasp Pi USB port. I'd prefer that approach, avoiding the need to add hardware. Thanks for taking the time to explain an alternative.

If I understood correctly your needs I solved 232->Eth conversion between my Node Red "Acom 600s web console" and the PA via its rs232 port by using an external (cheap) box (https://www.waveshare.com/rs232-485-422-to-poe-eth-b.htm). It's really useful and easy to implement by its administration web page. From node red I drive it via a TCP in TCP Out nodes and the module cares of converting into rs232 buffering and so on, absolutely transparent. Unique limitation is that it handles only rs232 Rx-Tx lines (so no control lines). Power it On and nothing else is required. For more details download my flow here: https://www.ik1bxn.it/wp/2025/02/13/acom-600s-lan-web-console-v-2-3-cat-synch-to-flrig-macloggerdx-rumlog-n1mm-flow-cleanup/

Hi Dave. Been a while. I originally had the RAAS-8a plugged into a PC and was using WA4MCM application to control it. It worked well from the PC. When I plug it back into the PC I see the followed defined for ports. The Silicon Labs one is the RAAS-8a.

The by-path directory is present and this is what is in there. I'm not familar with an USB HID device.

Hi Domenick

Is it possible the USB device is showing as a USB HID device?

The LP700 wattmeter is like that.

What happens when you plug it into a USB port on the PC?

Hello. Thanks Kyle for the information! I'm following your instructions and also using the YouTube video to install Ser2Net. My goal is to make use of the NodeRed flow to control the RAAS-8a Antenna Switch by WA4MCM. I have the RAAS plug into my RASP PI's USB port. The Rasp Pi is also running Nodered. I have run into snag. The /dev/serial/by-id folder is not present. The RAAS-8a is the only item plugged into any of the Rasp Pi USB ports. How can I get the folder by-id to be present?

Re: Solar 2.0 Released

groupsio@... (Scott Dupuie) — Wed, 14 May 2025 06:05:02 -0700

Version 2.1 addresses a minor bug that occurred when the probability of the predicted R value for 1-2 and 3-5 was the same but very small (e.g. 1%). This brings up a problem with a lot of APIs that I work with. They are not well documented. It's easy to call the API and see what the returned fields are, but often I don't know all of the possible values that those fields can have. This was one of those cases. I had considered doing more error checking on the predicted R value, but having a predicted value of R be 1% for R1/2 and also 1% for R3/5 made no sense to me. The code was modified to handle these fringe cases better.

73,

Dear group,

G0ABI asked me to also announce in this group. I created a dashboard for the Kuhne Electronic 2.4GHz up converter to visualize some of its values available on the serial port. The code has just been pushed to github. The repo is at:

https://github.com/phl0/MKU2424B-Dashboard

Feedback / pull requests welcome.

Re: W8BE Toolbar Flow

w8bea2b2c2@... (Mick , W8BE) — Tue, 13 May 2025 17:22:40 -0700

Craig,

Attached is my flow for the navbar. The flow shows the current solar idx's along with any geo magnetic storm alerts. It uses OpenWx for the current temp, wind direction, conditions, and barometric trend (up, down, flat). You will have to get an api key from them. The lightning indicator shows the current radius and last strike time if the icon is green. When the icon is red it shows the actual strike distance and updates the last strike time. There is a default configuration in the flow and a page where you can dynamically set the parameters.

In addition, I have css code for all the flows in the attached flow. If it blows up please disable the css ui template. You will have to modify it or use your own template in such a case.

Please see the attached flow
