Hi All, For anyone getting started with Node Red, first check out the WiKi to get your Pi loaded with an OS and Node Red. Next, check out these videos that Andy, VA3CW found on YouTube. The videos will help you to start using Node Red. https://www.youtube.com/results?search_query=opto22+node+red In the files section in this group there are plenty of flows to get you started. If you use a Flex 6000 series radio you can load my VITA49 and FlexRadio flows. I am modifying the FlexRadio flow shortly to automatically detect the model number of your radio and set the meter subscriptions accordingly. Please look for a read.me file in each file folder which describes any node dependencies and any other info required for those flows. A note to people who have uploaded flows - Create a folder with your callsign then upload your flows to that folder. Create a read.me file with Notepad or other text editor listing any extra nodes that you have installed for your flows. This will help new users to get up and running. I can assist in moving previously uploaded flows from the main file folder to your callsign folder. If there is anything else you can think of to help please let me know. 73 Dave wo2x

Hi all (10 of you! :) I want to make sure that everyone knows that this forum is not for just FlexRadio projects. It just happens that it started with Flex 6000 series radios. If you are working with other radios and amateur hardware, you are welcome to be part of this group as well. I would like all of you 'core' members to help reinforce that as we get new members to join. 73 Mike va3mw

For those using RPi - what are you using to break out the GPIO header? For our club station the RPi is contained in a Pi4 specific plastic chassis (really cheapo box) but I'm pretty sure that's not a good long term solution. Where possible I'd like to avoid making it into an octopus. Thoughts and pics graciously welcomed! 73 Andy VA3CW

Thanks to Alan and Dave for their help! This is Just a start on my station's NodeRed and looks kind of caveman compared to the others on here, I have very little time to work on this project right now but making some headway. I have 3 DLI WEB switch's (These flows work with older units and Pro switch's) a Flex 6600M, and Flex 6700 ( Problem with VITA49 running 2 radios, toggles back and forth really fast) HF Auto (need to add PTT drops when Radio tunes) FLEX PGXL Amp (Looking for a Flow if one exists) WN2 Power Switch (working on Flow) 73's and thanks for the help Bret WX7Y

Has anyone played with this yet? https://tech.scargill.net/lcd-display-for-node-red/ Mike va3mw

I have seen issues with certain devices using two flex radio's on the same network because both radios are stuck using port 4992, This causes the Flow's using UDP port 4992 to toggle between the two radio's frequency and band's This happens on Green Heron, HF-Auto and the VITA49 flows and I'm sure others, I being very much a NEW_BEE to Node-Red have dabbled with trying to change these FLows to work with the CAT TCP port numbers instead that we can set how we want and not stuck on 4992 so maybe some of you guys who are seasoned Node-RED code writers can figure how to change these so we CAN use these flows with two radio's on the same network. Thanks guys and have a great day Bret WX7Y

I changed the subject This worked 3 days ago before I pulled out the W2 and replaced it with the LP100A. oh, wait... maybe not as this looks like the LP100A settings now. You might have to revert to Dave's notes. 73 and Mike On Sun, Jul 12, 2020 at 10:23 AM Alan Blind <a.alan.blind@...> wrote: Dave and the group Good thought about using the full name of the FTDI cable. Here is a screenshot with the Rasberry Pi DEV file on the left, and the Node-Red Serial In node on the right. Node-Red found the DEV file, so that seemed like good news. However, the W2 Wattmeter does not respond to Node-Red. I am using the "official" Elecraft serial to USB FTDI cable. Node-Red appears to see and like the cable. Dave and Mike, you each use the W2. Could you send me screenshots of your serial in/out "advance" configurations, for the W2?

It was recommended to address them by the serial number of the cable which is unique with real FTDI chipset cables. I believe that is also how Flex keeps track of the cables plugged directly into the radio. Dave wo2x On Jul 11, 2020, at 9:15 PM, Alan Blind <a.alan.blind@...> wrote: ? Thanks, Mike. I will continue to try different settings. Alan On Sat, Jul 11, 2020 at 7:09 PM Michael Walker <va3mw@...> wrote: Hi Alan You might have to play in this area, edit serial port node. The LP100A starts with a ; that I use to start the listening process. However, I have found a bug on my USB ports that they don't listen at times until I change the Split Input time (or something) that caused the something to get reloaded it seams.

I have had success with serial to IP converters for remoting the ports. I am now trying to co-locate the Raspberry Pi and use cables for the serial connection. However, when I use a Serial to USB FTDI cable, my Node-Red sees the cable connected to the USB port, Node-Red says it is connected to the port, but will not pass data thru? All of the basic serial settings are per the device's instructions. My current instance is with the W2 Wattmeter. I am using the Elecraft supplied serial to USB FTDI cable plugged into the Raspberry Pi USB2 port. Are you using FTDI Serial to USB cables? I know you have previously used the Serial to IP convertors which I too have used successfuly. Did you find any other settings or drivers necessary to make the cable work on a Raspberry Pi?

I'm adding more display info. I took out the Gate since the LP100A handles clearing the display nicely. I'm reading every 100ms to try to catch a nice Peak value, but I am checking with Telepost to see if I actually need to do that or if the LP100A actually holds peak from the last x-milliseconds. Still a play in progress! :) Mike <image.png> [{"id":"6bf0f43f.f0ad1c","type":"tab","label":"LP-100A","disabled":false,"info":""},{"id":"98aa4756.b21c48","type":"serial in","z":"6bf0f43f.f0ad1c","name":"LP100A In","serial":"8c8041f4.047d2","x":200,"y":340,"wires":[["ada0955c.a21b08","1bbc73c5.a5115c","8b20a0ee.cc4e2"]],"info":"Under normal operating conditions, if the W2 is sent either an \"I\" or an \"i\", it returns a string of information about the state of\nthe Sensors, the Range settings, some internal settings, and which Sensor is active.

The following files have been uploaded to the Files area of the [email protected] group. /wo2x flows/ElecraftW2_beta4.json By: David De Coons wo2x Description: Node Red flow for the Elecraft W2 wattmeter

Hi all, I have finished the display portion of the W2 wattmeter flow. What control functionality would you like to see? Forward power meter in auto range or manually set? (I personally like auto range). Sensor auto scan or manually selectable? Or a choice between the two? What other controls? Once I get some feedback I will be able to have a flow publicly available to test. 73 Dave wo2x
