Looking for this K6HN azimuth flow
I am looking for just the azimuth flow in this group, I scoured the file section but don't see it.  .

Changing font color by value of msg.payload
I'm trying to make my OUTPUT SWR font change from GREEN to YELLOW to ORANGE to RED as the SWR value climbs past certain levels. Here is what I've been trying to use, but it doesn't work.?

Hi Roger.?
Check out the file section on this site. Alan posts his flow there. (I do need to start working on “housecleaning” there).

Re: ERROR:Input not a JSON Array (FRSTACK)
I figured it out, the tabs showed disabled because they were ...wait for it.... DISABLED. Thanks Alan for you help, you put me on the right track.

Re: ERROR:Input not a JSON Array (FRSTACK)
Alan, that helped alot, Since those json files were included in the same folder where I got the sample file frstackNodeRedV108.json,? I thought I had to import those also (only at this for 5 days). I? added the IP address of my raspberry pi that frstack is installed on with port 5025? in the connection tab as you mentioned. The problem I can't figure out is why a bunch of the flow tabs are inactive as shown in the attachment. All other features of frstack seem to be working with my? 6700.

Re: ERROR:Input not a JSON Array (FRSTACK)
First the "ERROR:Input not a JSON Array" message. ?Typicaly means the nodes that parse to JSON are not seeing an input from FRStack. Confirm you are running FRStack on a Linux (Raspberry Pi" device. ?If you are running on Window, there are different setups. Confirm FRStack is running: ?run command, " systemctl status FRStackWebApi" and look for the "active" status. If not, reinstall dot.net and FRStack.Perhaps you did not set up the IP to your device running FRStack. ?On the Connection Tab, double click the "Set Parameters here" node. ?Enter the IP address of the device running FRStrack, port 5025.  Now for the other "errors".
appsettings.json
FRStackWebApi.deps.json
FRStackWebApi.runtimeconfig.json
These are not errors, rather files contained in the " /usr/local/frstack" directory. ?Strange you are seeing these.

Serial Control of the ERC-4 Rotator Controller
Hello Everyone, I have uploaded a flow to control my ERC-4 Rotor Controller via a USB Serial output of my Raspberry Pi running Node-Red. I haven't posted much on Groups.io, so I hope it shows up.? Hopefully it will be in the wb0smx Flows directory.? (Note** Moved to !1! Flows by Type/ROTORS/ERC Controller) This is the first Node-Red programming I have attempted.? While I have some experience with older structural languages, I am finding the Node-Red process intriguing.? I really like having the web interface. ERC_Control.json This flow is used to send commands to and receive responses from an ERC-4 Rotator Controller made by https://www.schmidt-alba.de/eshop/ The flow uses the Yeasu GS232B protocol to talk to the controller via a serial data connection. This flow is an adaptation of one created by WO2X located in the [email protected] filesystem.? The original was in the wo2x Flows directory and named PSTRotator.json Dave's original flow used network connections to talk to the PSTRotator program running on a Windows machine. I took Dave's flow and modified it to talk directly with the ERC4 Rotator Controller via the serial USB port on my Raspberry PI 4. That way I didn't need a Windows machine in the picture. There are two major functions involved in rotor control. ? 1.? You must send commands to and receive responses from the control box. 2.? You must interface with the human by accepting input and presenting output. #1 is accomplished by a Serial Request Node that accepts inputs from a variety of buttons and input nodes that the human manipulates.? Commands are sent out the chosen USB port as a serial stream, and the program waits for a response from the controller.? There is a 2-second configurable timeout, in case no response is received. One of the inputs to the Serial Request node is a periodic request for an Azimuth position from the controller.? I have this set at 1-second rate, and it runs all the time. The other inputs are commands to Start Rotation CW or CCW, Stop Rotation, or Rotate to specific headings input or selected by the operator.? Once one of these commands are sent out, the flow continues polling for azimuth position data. #2 is accomplished via a set of buttons dedicated to moving to specific azimuth headings, 1 for Europe, 1 for Russia, 1 for North Africa, etc... There are other buttons for starting CW or CCW rotation without a target. Anther button sends a STOP command to the rotator controller. There are two input fields to manually enter a heading.? The top one is a numeric heading that may be stepped up or down one with arrow keys.? The other is a text input field that lets you freely type in a new heading. A tab or key will send the heading out. The headings entered are all validated to insure that they are in the range of 0 - 360 degrees, and that only numbers were input.? If non-numeric data is encountered, or the heading is out of range, no command to move is generated. Finally, response from the ERC-4 controller is parsed to extract only the numeric heading, and sent to a compass control for display. -- Randy WB0SMX

ERROR:Input not a JSON Array (FRSTACK)
frstackNodeRedV108.json? imported fine.? Three of the FRSTACK flows show this error when attempting to import. ERROR:Input not a JSON Array
appsettings.json
FRStackWebApi.deps.json
FRStackWebApi.runtimeconfig.json
I am only five days into NodeRed, is there something common to look for when this happens?

Re: Node Red article in QST September issue
I'd like that Dave.? That would be very helpful to me.? I've been learning JavaScript as I think it would be helpful to understand some things.? Maybe that is the wrong approach.? I wanted to understand the basics of Javascript to be able to interpret the payloads. Things like setting variables and arrays and some basic?programming statement.? Perhaps there are some other rudimentary?things one should review before attending a session like you propose????? On Fri, Jul 30, 2021 at 2:28 PM David De Coons wo2x < RocketNJ@...> wrote: Hi Bruce
A follow up article taking a dive “under the hood” is a good idea for QEX.
Not sure on a book. There are plenty of reference sites and videos available. I am not a programmer by trade but love to find answers on how to get things accomplished (not just Node Red). Through my whole career I’ve never been afraid to take on a challenge.
My best advice to people here that might think Node Red is too difficult is to start with a couple of basic flows. Make use of debug nodes and connect the debug node to various node outputs to watch the payload (data) and observe how it is manipulated with each previous node.
I’d love to do a Zoom session open to all where I start with making a connection to the Flex SmartSDR CAT via IP (easier for me than serial) and go step by step to get info, parse it, then format to display on the dashboard. This is pretty straightforward for some but will assist others who want to have a CAT (or CI-V) connection and be able to communicate to and from the radio.

Re: Node Red article in QST September issue
Dave,
I think it's great that you and others are very willing to help members of this group both individually and collectively. However, I think a book that covers the basics of Node-RED and then explains how to apply those basics to typical ham radio problems would be useful to a wider audience and seems consistent with some of the other softcover books published by the ARRL. This group appears to consist of people with a wide range of technical backgrounds, so some just need a little nudge in the right direction to solve a problem, while others are mystified by the basic components and terminology. Many will perfectly understand your last paragraph below, while others will be lost.
