Re: Hamvention 2025 Node Red Presentations
If you missed my Node Red at Hamvention, here it is:
?
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
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.

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

Re: How To : ser2net - Serial to Network Media Converter with a Raspberry Pi
¿ªÔÆÌåÓýHi DomenickIs 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? 73 Dave wo2x Sent from my waxed string and tin cans.? On May 15, 2025, at 11:23?AM, Domenick Fusca via groups.io <domenickfusca@...> wrote:

Re: Solar 2.0 Released
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.

Dashboard for Kuhne MKU2424B up converter
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: Feedback / pull requests welcome. vy73 de Florian DF2ET -- Florian Wolters, DF2ET LOC: JO31ol |

Re: W8BE Toolbar Flow
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

Re: Flex6xxx and ESPHome or ESP_Async_TCP_Webserver
¿ªÔÆÌåÓýAnd to add a V3 layer of security, you can use TailScale or other VPN to access the Node Red web page. I do that with both remote accessible stations.?TailScale works very well.? 73 Dave wo2x Sent from my waxed string and tin cans.?

Hamvention 2025 Node Red Presentations
Hamvention is upon us!? Hope you can make the show.? If you want to learn more about Node Red at the show, here are some things you might want to put on your calendar.
?
Saturday Forum Room #4 at 9:15am - Remote Ham Radio.? Mike Walker (VA3MW) and myself will be presenting how to remote your radio, with a special guest on a new product announcement!? You don't want to miss this announcement.? We'll be touching on some Node Red flows within the presentation.?
?
Saturday Forum Room #4 at 2:40pm - Node Red How To.? I'll be presenting a few slides at the beginning of the forum and then head directly into a hands on demo.? I'm not going to side show you to death with this one.? I've already done that and the guy in the front row napping after lunch in the air conditioning made it real clear the slides were a substitute for some Trazodone pills, so we are changing it up.? We'll start with a blank canvas and build some easy flows then we will plug in a KX3 and control the radio from Node Red with only a few nodes.? Easy stuff.? We will also load some flows we downloaded from the files section in this group for a KMTronics 8 port relay board and control the relays.? At the end we will take 15 mins to talk about the Sierra Radio Station Controller Node Red install and talk about some real world uses.
?
If you want to see the full Node Red presentation from years past: https://youtu.be/0G1RXr9k_jA?si=UJiJ37heXNCLK4Kb
?
I think some of the forums will be streamed live and/or recorded for later posting.? Watch the Hamvention YouTube page for those streams. ?
?
Come say hello before or after the forums!??
