Moderated Re: Copying flows for a new Pi

 

Assuming your nodes are recognized,? I would check which group the nodes are in.? Usually I see that when I import flows,? only 2 things really get in the way,? I do not have the correct nodes installed and or they are in a group 'unassigned'.? Node red will throw an error when this occurs.? ?Use the drop down to see what group the offending nodes are in.? Odds are it is in an unassigned group.? If this still does not resolve the error, then post the actual error message you are seeing.

Moderated Copying flows for a new Pi

 

I exported all my working flows, and wanted to put them all on a new Pi that I can mount in my rack with the radios.
I used "Export All Flows", then I imported them into the new Pi. There were a lot of Unrecognized Nodes. I tried installing those in the palette but the whole thing isn't right.? When I tried to deploy, it says that several items are not configured correctly.
Am I doing this all wrong?

Re: Sub Meter SWR

 

My idea to move the SWR to 4998 actually worked.? ?Now Fan speed and SWR don't step all over each other.? ?I need to clean the code up to get the start up sequence for each udp port done but that should be easy..

I learned a couple of things doing this.? ?1st when you are looking for data in the array and expect varying size look at the node look at the node buffer size.? This will tell you which msg differs in size.? 2nd.? is you can run multiple tcp connects into port 4992 into the Flex.

Re: Sub Meter SWR

 
Edited

Thanks to Mark,? I am now able to do the math to get the correct SWR value,? however I ran into an interesting situation.? ?I am subscribing to 2 meters 'fanspeed' and 'swr'.? ?I noticed that the return values seemed to be stepping on each other.? Take a look at this debug output... The first payload has 32 bytes and is the SWR output.? 30: 0 and 31:144.? ?The math gives you an swr of 1.125.? ?I am subscribe to 2 meters and the data does not come in at the same time.? I found that when there is no fan speed data the swr data comes on byte 30 and 31.? ?The 2nd payload is 36 bytes and contains both fan speed and swr data.? However when the fan reports it's data it occupies that array slot and now the swr data move to the 35 and 36 byte slot.? Also the data in that array is now in hex not decimal.? ?



I am thinking maybe the way to go is to run the swr on a different udp port (i.e 4998).? ?Wondering if anyone has ran into this..??

Re: Node Red Overview Zoom (Youtube) Summary

 

Just to add to the above comments...

Node-Red can run on any computer and likely many of us do have it running on multiple machines for testing and development. A Raspberry PI is attractive as it is inexpensive, is easy to maintain OS software, it can left running indefinitely without the need for a monitor or keyboard, and lastly, the IO interface built into a PI can be used for direct interface to control external hardware together with the fact that a PI is so small, it can also be deployed remotely.

Dave:

?

Here is an idea to help the new people that don't yet grasp what is going on with Node Red:

?

Do you notice how many times we get questions about "Why do you run Node Red on a Raspberry Pi?
Why don't more people run it on their Windows 10 PC?"

There is a natural tendency for most people to think of any computer topic as "A Program", a single part
thing that you put on your windows PC and just click to run.

?

But why:

This is because (in my opinion), that none of the introductory videos or articles start off explaining with a diagram
that there are TWO parts to any node red installation (and that is what makes it so popular):

?

1.? ?The controlling User Interface:? ?A Web Browser
2.? ?The Flow:? A collection of javascript and node.js code that runs on a computer.

AND, that #1 and #2 do not need to be on the same computer.? ? AND, that since we want "The FLOW" listening
24 x 7 (just like Alexa), we usually?place the FLOW on a small computer that wastes very little electricity, hence
a Raspberry Pi 3 or 4.

?

The four major benefits that are creating the popularity seem to be:

?

1.? Node Red can easily interface to and control a wide array of dissimilar hardware, sensors, and control
boxes and relays.? It can easily tie all your dissimilar station equipment together for remote or local control.

?

2.? I can run it on very low cost, small, and inexpensive to run (24 x 7) micro-computers like the RPi.

?

3.? Using a web browser user interface, I can talk to it (control it) from my cell phone, tablets, or any PC
anywhere (you can even tie it into Alexa for voice control).

?

4.? I can develop/edit/create in Node Red using a web browser based graphical Editor, again, from anywhere.

?

Extra Credit:
5.? There is a large and growing community of users, who share ideas on forums and have a passion for helping
each other.

?

= = = = = =?

?

If more of the first timer, first day, tutorials and introductions started off with JUST THAT ABOVE, people would
have much less confusion during their first week or two of Node Red learning.

?

Cheers,

simple flows Amplitec remote antenna switch + YAESU GS232 rotor

 

¿ªÔÆÌåÓý

I uploaded the following two flows:

?

  • Amplitec SW3000-6 antenna switch via node-RED

The switch is available with in several versions with 4/6/8 antenna ports and consist of the switch itself and a seperate control box. Both are connected via a 9-pin DSub 1:1 cable. The control box has a USB port, which is connected to my Raspberry.

Antennas can be switched manual via the control box or via web browser. Current settings are updated every second.

?

  • Yaesu GS232 rotor interface

I am using a ERC Mini DX interface with my Yaesu G2800 which uses standard GS232 protocol. The simple flow shows the antenna direction and buttons to turn the antenna.

?

Both flows are very simple and do not contain any error handling. I am sure there¡¯s an easier way to do it, but it works. ?

Michael

Thanks Dave. It takes a lot to excite me and I have to confess I am very excited after I came across you guys and node-red is bringing everything together in one GUI was always my hope.

I will chime in on this with a comment.

I have a flow which sends the radio¡¯s TX frequency to a GHE antenna switch. I wrote that for Santiago. That flow can probably be used as a starting point for having the Pi talk to the GHE equipment across the network, then build the interface to the equipment in Node Red to consolidate all normally used controls, meters, etc on a single web based dashboard.

Alan,

in my case I am running GH server on a windows PC and all rotors are also connected to the server PC. If I ad a Raspberry Pi to this does that mean the PI will connect to my GHE remote devices via the network?

Also, can you recommend what to buy when I order the Raspberry Pi. What about for USB port expansion as I need a lot.?

Re: N1MM SO2R radio indicator

 

You will want either fans or heat-sinks. You almost certainly don't need a fan if you use heat-sinks.

I don't run fans, but I do run with little stick-on aluminum heat-sinks. They are included with the CanaKit.

There are also full rpi cases you can buy that are made of aluminum and have excellent heat dissipation. I use one of those for my home automation pi which constantly has high cpu.

If your pi is in a server closet with poor ventilation then perhaps fans would be helpful.

I would suggest a Pi 4 with minimum 4 GB in case you want to run more things on the Pi in addition to Node Red. I have installed a dynamic dns client on the Pi which updates my dynamic dns provider with my public IP address.?

Node Red and FRStack will run on a Pi 3B but not a big price difference between a 3b and a 4 with 4 GB ram.?

The "Canakit" has consistently been very reliable for my ops. I have a dozen or so of them--some 5 years or older--and none of the components included in them has failed, and the power supply they provide has no noticeable RFI (but I put a choke on them just in case). You can piece the canakit components together yourself for a slight discount if you prefer or if you already have a clean PSU and a cooling solution etc.

Once you are satisfied, you can put the RigPi card back in and sell it (if you desire) and get a new Pi. Keeping the RigPi SD card intact is recommended if you ever sell it or want to use it again in the future.

Re: N1MM SO2R radio indicator

 

Some prefer it but I would recommend having a pi be dedicated to only node-red+frstack. I say this because it's easy to wind up with different software stacks that require different versions of system libraries or that cause temporary high periods of CPU/memory/disk-io.

This happened to me when I was running node-red+FRStack on the same pi as some home automation software. There would be CPU spikes at random times which prevented me from SSHing in or accessing the dashboard during extended QSOing. The pis are inexpensive enough and I really don't want them to stall out while controlling my rather expensive radio equipment.

My node-red+frstack is based heavily on Alan WA9WUD's flows and it runs quite comfortably on a pi4 with 2gb of ram.
