Re: File /!1! Flows by Type/RADIOS/HRD_ve9gfi_2022.06.08.2130.json updated #file-notice

Edited

Hi Adrian,

?

I created two dynamic dropdown lists, and each one works.

Then I added a Switch node to select what list should be used, based on the getradio response.? ? I'm stuck ... but I wanted to share that this will work for your radio and mine, automatically, if I can get the Switch node to cooperate.

I tried using both the msg.payload output from MQTT and the flow.getradio variables... same response (not working).

It's Saturday here, and I need to run the roads ...? If you see my error, please let me know.

?

EDIT>>>? The one thing that comes to mind is that perhaps the getradio and mqtt string is UTF16 and is not matching my typed in string.

Perhaps the file is in a directory that requires administrative privileges??

I suggest two ideas.

1- Move the file to different locations, like the documents directory.
2- prepend a "sudo" to your Node-Red read file command, with a password. ?The command will look like this: ? "sudo -S <<< "password"?

Permissions question...

#7966

Hi,

I am trying to read a file under Ubuntu...  The file is under my home directory, as shown in the screen capture...

I am using readfile, and all permissions are set to read/write for everyone on system, for the target file.

I know this is some sort of permissions issue, but I don't know what it is...  Any suggestions?

You can set a jumper in the meter or use a Y cable and connect two sensors parallel. The sensor with highest reading will show output.?

This is fine for amp output in SO2R but will not show input and output of amp at same time.

I set the jumper in the PM 2 meter which parallels the two sensors. Works fine.

Programming help needed - CRC8 calculations

#7962

开云体育

Hello all,

?

Working on a flow for the Array Solutions Power Master II watt meter.

?

I have most of it working except a couple of commands where I cannot determine the CRC checksum. I am NOT a programmer so therefore I have met my match and hoping some of the brain power in the group may have an answer.

?

The meter wants an STX + command + ETX + CRC + <CR>

?

I am attaching below the information I received from Array Solutions on how to calculate the CRC. According to their info the CRC is based solely on the payload and not the STX or ETX (hex 0x02 and 0x03). I would like this to be able to be put into a function node to calculate a msg.crc based upon payload.

?

If a payload of v? is sent the CRC is 0x42 0x42 hex or BB ascii.

?

The below info has the CRC table they use. So looking for someone with programming that can come up with a function to determine CRC for a payload.

?

PowerMaster VSWR Meter serial protocol

10-17-06

?

There are 3 baud rates selectable from the meter menu. The default is 38,400, no parity, 1 stop bit.

?

The first character of a packet is an STX ($02). This is followed by the packet payload. The payload is followed by an ETX ($03). An 8 bit CRC is appended after the ETX. The CRC covers the packet payload, not the STX or ETX. Finally a <cr> ($0D) is appended. Line feeds ($10) may be added, they are stripped by the receive protocol.

?

Here is an example of the packet CRC testing:

?

byte

CRC_Check(void)

{

byte *ptr, b_udata, b_crc;

?

ptr = c_UserInBuf + 1;? /* skip STX */

b_CRC8 = 0;

while((b_udata = *ptr++) != '\0')? /* end of string safety limit */

????? {

????? if(b_udata == ETX)

??????????? {

??????????? b_crc = MakeHex(*ptr++) * 16;

??????????? b_crc += MakeHex(*ptr);

??????????? b_CRC8 = ~b_CRC8;???????????? /* CRC sent complimented */

??????????? if(b_crc == b_CRC8)

????????????????? return(0);

??????????? else

????????????????? return(1);

??????????? }

????? else

??????????? CRC8char(b_udata);

????? }

return(2);? /* missing ETX */

}

?

void

CRC8char(byte d)

{

b_CRC8 = crc8revtab[b_CRC8 ^ d]; /*crc must be complimented elsewhere*/

}

?

A lookup table is used to calculate the CRC for speed.
const unsigned char crc8revtab[256] ={

Re: Stream Deck and Node Red

#7961

Hey David?
I have been following your stream on integrating Stream deck into Node Red.
I have managed to get my Icom IC-7300 to display the frequency on the display dashboard using the CIV get freq that works fine.
So now i have that working i was experimenting getting to display it on a button like yours.
I was looking at your Youtube video and one of the stream deck buttons second row 4th from the left displays the freq.
Im assuming that is a flex radio thing?
I couldn't see in the flow chart how you brought in the freq display to the stream deck.
Do you have any screen grabs or tips how I can replicate that now that im getting the freq to display on the web UI.
Im hoping i can share my progress on making some IC-7300 available to the group
Cheers Glenn

Basics of Node Red Presentation - Arizona Outlaws Contest Club

#7960

I gave a presentation to the Arizona Outlaws Contest Club last night, mainly about my contesting dashboard, but they wanted to know more about the basics of Node Red.? I put together about 3 presentations for them and this is what came out of it. I spent a good 45 mins brain dump of Node Red and basic configurations on how to get started.

At the end we talk about the contest dashboard, but I think the first part will help some of the new people get started with Node Red if you haven't already.

Re: Getting started with Node Red

#7957

Wow - Thank you Alan that payload.id worked in seconds - such an easy fix
It fixed up all my hours of attempts at failed patches.
Thanks?
- and Ron yes I could get an online weather service ( actually my sensors feed into those online services ) but as a true Ham I wanted to extract the radio version direct from my sensors. More of a learning first project for myself to tackle bigger Ham projects, I thought start simple with the temperature extraction. I actually might extract it and do a side by side comparison on the side of my display to see how far my sensors are from the online data.

I was struggling because Now I know those sensors have a lot of data and i wrote a function script to test the extraction of the data that worked but i couldn't extract the numbers. Thanks again Alan I wouldn't have ever gone down that payload.id path.

Now that I have that as my first dip my toe in the water experiment.
The next project is integrating an elgato stream deck and an Icom IC-7300. Alan I think it was your video i was looking at that has integration for the Flex radio
I noticed there was an Icom CIV and i thing a 7100 control so i might give those a go and see if I can adapt that to the 7300

This is the script i did in the function to extract the temp/humid/etc
(var o = msg.payload

msg.payload = o.temperature_C;

return msg;)

Re: Getting started with Node Red

Glenn,

I don't have an answer to your question as I have not looked at the flow.?

I am going to offer a different solution that you can feel free to ignore. I elected to get my WX data from an online service and use Node Red to display the data on my dashboard. It eliminates the need for local sensors and, in my case, since I'm sheltered, wind data would be very inaccurate.

You can check out the data for Sydney at the link below.

Use requires registering to get an API key (no cost). This would also allow you to pull data from different locations which might be useful based on your QRZ page. If you'd like, I'll share the flow.

Hey there?
Great group here
I am taking the advice and starting small before i get onto bigger things
So i have started with taking the weather data from an sdr dongle
I can get it to display no problem but it mixes the values
i have been trying to use RTL-433 as the inject to display weather on my shack display.
The problem i have is the temperature value coming from the SDR is mixing multiple sensors.
So the same display rotates the different temps from the different sensors .
the sensors have different channels and different ID's. if i try and block the ID it seems to block everything
one sensor is?id:?339746605 the other id:?-2139593976
i thought the obvious way would be to block the alternate ID
maybe its too late in the night but i just cant seem to divert one sensor?
i have attached the map?
any tips would be good
I have been trying everything but my json knowledge is poor.
I tried functions/gates/seperate switches/filters but cant think of the correct way to do it?

Also, and to correct my first response. ?I just noticed the id text were blue in the debug window. ?This means they are a "number" variable type. ?If they were red text, they would be a variable type of "string".

In the switch node, you must specify the type of variable you are using. ?Here is a corrected screenshot using a variable type of "number". ?My first response showed a variable type of "string".

Re: Getting started with Node Red

#7950

Glenn

An easy method is to use the "Switch" node.

I see the the "id" comes thru as "msg.payload.id". ? FYI, if you expand the JSON by clicking the small arrow next to the object in the debug window, you can see a more straightforward path to the desired variable. ?Click on the "copy path" to move that into the switch node, "Property" box.

The switch node can use "msg.payload.id" property, to only allow the full object to flow, only if the value meets the value set in the selection. ?Here is an example using your data. ?Each sensor's variable will flow to the respective output of the switch as msg.payload, or whatever you have set up in the source nodes.
