Great presentation. Got hooked on the Node-RED stuff!

Mike-VA3MW

My hope is that we all share our NodeRed flows so it helps people get started.

This is where most of the chat is happening https://community.flexradio.com/flexradio/topics/remote-operating-and-node-red

+1 on Node Red. Mike and Andreas, N6NU got me hooked when I was in the hospital, bored. I wrote flows for controlling and monitoring a KPA1500 amp, DLI Web Switch Pro, and Idiom Press serial interface for my rotor. Good stuff indeed. The DLI Web Switch Pro can be set up to ping multiple sites. If it fails ping to all sites three times then it reboots user defined outlets. (Cable modem, router, local maintenance PC). Nice thing is the switch also supports several programming languages to remotely control it. Dave wo2x

Hi Craig

On the PI, none.  All my switches are controlled by HTML links.    This is the switch I use https://www.kmtronic.com/lan-ethernet-ip-8-channels-web-relay-board.html

You can see the examples here https://info.kmtronic.com/control-kmtronic-lan-relays-using-browser-bookmarks.html

Hi Craig

The KMTRONICS has status XML that it echos back that I capture and that is what sets the LED colour.  So, I have some full circle communication.   As for Temp, that is done on an I2C buss.  The web server runs on the same RPI and is part of the NodeRed installation.

If you want to monitor a bunch of sites, I would look into MQTT to manage the distribution of the information.  In the Steppir and Rotator flows that N6NU wrote, he uses MQTT to send messages to other operating stations.

Thanks Alan.  Today was a hectic and long day and I am a bit behind on emails.  I will get to them.  73

Thanks, Mike.   No problem.   I caught the end of your afternoon video and heard you also had a morning of working on your water supply in the lake.

Not sure if you sent the "completed" SteppIR code.  See my screenshot with questions noted.  If it is not finished, that OK.  I was just trying to make it work without success.  I have other options if yours is "work in progress".

Hi

My flow is heavily modified and is not the flow I am currently using.  Dave WO2X sent me the one we received from Andreas, N6NU.

However, let me see what I can piece together.

TCP 4002 is from a PSTRotator output.  You can ignore that injection point.


Steppir IN is from the RS232 Port that is connected to the Steppir.  If you open it up, you'll see more about it.  The Steppir controller is 4800 8N1 for a baud rate.

Steppir1Status is from the MQTT server and that is where we get the frequency.  That flow, attached is a work in progress.  What it does is connect to the radio on port 4992, send a command and then look for a variety of things.  

From Flex Queries also comes from the MQTT server that the flow (attached) sends to.   I am not sure I sent that in the beginning.

Sorry, I know this is clear as mud.  You may have to dig into it a bit.

Mike

Thanks Mike.

I understood the inputs and outputs, just could not get the SteppIR commands to work.

I am using the Flex API flow, above, in several of my flows.  I have learned a lot about the Flex API by understanding how the flow works.

Thanks for working up a flow to share.  I would like to add a "retract" button to my dashboard and was looking at how to use Node-Red, alone, to get this done.  If you can share your working flow, that would be great.

I am making progress with the Node-Red SteppIR flow.

I have added the command buttons to the GUI flow for "Home", "Calibrate" and "Re-Enable".

I added code to the flow to add the necessary HEX commands to position 8 on the 9 byte ASCII message for each of the new set command buttons.

My flow now receives all of the status information from the Stepp IR.

However, my SteppIR SDA100 controller will not respond to commands from Node-Red.

The serial cable from Node-Red, in and out, both look good.

Questions:

How do you have the SDA100 configured with regards to serial in/out connectors and configuration?

- are you using the "data-in" DB9 from the Flex USB cables for frequency input?
- are you using the lower DB9, data-out, for your Node-Red Serial in and out?
- how do you have the transceiver configuration set up on the SDA100

Hi Alan,

I just loaded your SteppIR flow and going to look at the code to see if anything stands out at me. I do not have a SteppIR so will need you to test any changes. We can do it via TeamViewer whenever you have time.

Thanks go out to Mike, Dave and the SteppIRs developer, Andreas for helping me set up a working flow.

I now have the SteppIR flow incorporated into my Flex 6600 Dashboard.  I had to modify the flow from a multi-element yagi to a single element vertical antenna. (mainly removing the code for "180" and adding code for "3/4" and eliminating unused  element motors).

I have a separate tuning board in the SDA100 controller that operates the "Tuning" LED and provides a direct TX inhibit to the Flex if the SteppIR is moving.

I also have and use the SteppIR Transceiver board.  That provides frequency information to the SteppIR SDA100 controller independent of the Node-Red Flow.  If I have "Track" selected, the Antenna will track the Flex Frequency.

In my Flex 6600 Flow, I have a "Master" button.  When I push this button, everything shuts down including grounding the HF antenna.  I added logic from the "Master" button to "Home" the SteppIR element.  When I restart the Flex, if the Stepp IR mode is in "Track", the SteppIR will automatically go to the frequency sent directly from the Flex Radio.

Here is a screenshot of the dashboard.

Awesome... You read my mind on the Master button.  I need to code one for Lightning that does that over a 2 minute period.  Shut down the radios, then the power supplies, etc.  Nice work!

Alan

Mike..... ...About that lightning.....  You have discussed that in your videos and I was wondering.....is there an API Key, like one can get from Weather Underground, to do HTTP requests for, in this case, lightning, in my (your) area?

I already shut down the station automatically on low voltage (if I lose power and my UPS battery power is discharged).  It would be useful to add "lightning" to the ways to shut down the station.

I have seen simple flows that use Weather Underground, for trigging Node-Red, but I have not yet looked to see if the same can be done with a Lighting API Key.

Shutting down the station has been a neat project.  Of course, you don't just "pull the plug".  Some devices are shutdown but need power, such as the Flex.  Also, I must maintain a UPS source for the LAN infrastructure, so I can remotely get it going again.  More on that if you are interested.

I found a way to get a Lightning trigger.  Full description is in the Remote Operating discussion.

Thanks Mike this was great info and super video!!!

Christopher Platt

Thanks for the video Mike. I have a remote station down in VK. I use the Remote Rig web switches to control stuff - very stable over the last 5 years. I also use Lantronix 240V switching unit to control LAN switches, 24V power supply, 12V power supply with a battery backup via a West Mountain Radio PSG40. I use the Microtik 4G routers/firewall which are also nice and reliable but hard to setup.

Just got a Flex 6600 to replace the K3 and K3/0 setup.

Questions

How to you cope if the SteppIR SDA100 box power cycles (as it doesn't turn back on)?

Do you concert your RS232 to a LAN Port using the Lantronics and/or Moxa products? This may I can control the rotators and the Alpha 9500 etc with out having to remote in (using Splashtop Personal)

Thanks again for the video which had given me some more ideas
