K3NG arduino-based rotator interface via Pi4 with NodeRed?

 

开云体育

Welcome to the group!

?

You could export the flows from the cloud based server and install Node Red on a Raspberry Pi at the radio site. In the WiKi section of this site are some articles on setting up Node Red on a Pi as well as securing the Pi for remote access to the dashboard.

?

The flows in the file section are available to download and modify to your specific use.

Dave WO2X suggested I visited this forum with my query.

A friend built for me an Arduino-based rotator interface for my Yaesu G-1000DXA ( ) . I’ve been using PST Rotator to control it via a remote PC and TeamViewer so that was fine. However, I wanted to do away with the PC and TeamViewer at the remote location because the internet speed is not great.?

?

I am currently controlling the Yaesu rotator and antenna switch via the Node Red flow attached. The Node Red is hosted temporarily by Remotetx.net. So here are my noob questions:?

?

What are the steps if I wanted to migrate this flow from remotetx.net to another server? Does it have to be cloud-based and are there hosts you recommend??Assuming I upload the flow to a cloud-based server, how do I access it remotely via the Pi4??

?

I saw other NR controller flows for antenna switch, rotator and amp control on this forum, like Dave's below.

Would it be possible to modify my current NR flow or configure an existing flow, assuming the owner is sharing it???I am attaching my json and a screen grab of how the controller currently looks at remotetx.net.

I use K3ng rotor setup, and you can download my Flo w here at the group.

After the IP:1880, add a forward slash "ui" for the Dashboard.

Hi Dave

Sorry for the noob question but I did what you suggested and I'm stuck. I used the Wiki section instructions to install Node Red on the Pi4 at the remote location via the PuTTY app, then installed the nodes recommended by your list (node-red-contrib-stoptimer3 gives errors and I couldn't install) and then imported a couple of flows which I used for controlling my antenna switch, rotator and KPA-500 on remotetx. However, I don't know where to go next. I read and re-read examples like 'create your first flow' and maybe I'm not used with the terminology, but how do I 'browse locally' these flows? Where do I find the address of the flow I deployed so I can access the panel and the automation process? I read about a http://localhost:... but where do I find this specific address in the flow so I can browse to it?

Thanks,

Chris

Hi Chris,

?

Welcome!

?

To access the Node Red editor you use the IP address of the Pi followed by :1880

Example 192.168.1.25:1880

?

The Node Red dashboard can be accessed by using the IP address of the Pi followed by :1880/ui

Example 192.168.1.25:1880/ui

?

In the editor, clicking the down arrow in upper right corner and selecting dashboard will allow you to edit the groups and main page for the flows. That will allow you to move dashboard nodes between groups and customize the dash to your liking.

?

Maybe we can do a Zoom session some time for our new members to help go through the basics to get started.

On pain meds in hospital currently so if any typos in reply, I am sorry.?

I would recommend all external equipment to be connected to the Node Red server.?

Then Node Red server (PI4) be on same LAN as radio and other network equipment.?

Now when you want to access and monitor the dashboard you have several ways. The most secure is to use a VPN to access the LAN IP of the Pi followed by:1880/ui?

You can use a service such as TailScale which is free. TailScale allows only registered devices outside your LAN to access other registered devices on your LAN. You control the actual devices that have access via the TailScale VPN. So you can enable the Pi for TailScale and your remote laptop but not your home PC which may contain more secure information. Your decision.?

Another way is to password protect Node Red editor and dashboard then poorer forward a non-standard port to the Pi’s LAN’s Ip and port 1880. Not as secure as a VPN.?

Others can make decisions on various ways you can do it, then choose best method you would like.?

[Edited Message Follows]

Hi Dave,

I've now managed to access the various flows designed for my antenna switch, rotator and the KLA amp, and they all work but only when my laptop is connected to the same IP router that the RPi is. As soon as I connect from another IP address or internet router or via 4G there is no access to the flows. Any idea why that is??

Did you "authenticate" your Tailscale on the Raspberry Pi? ?If not, on the Pi, run this command:

sudo tailscale up

You will get a URL for a web connection, plug that into a browser, and that will take to a page to authenticate the Raspberry Pi TailScale to your account.

Now on the Windows side, in the bottom right tray, right-click on the Tail-scale Icon:



You will see a "log in" line. ?Go to that and authenticate your Windows Tailscale.

You connect devices by using the "Tailscale" IP address for the device. ?This will work from device to device via the Internet or on your LAN.

To find the Tailscal IP address for the desired device, again, right-click on the Tailscale Icon in the lower right tray and to the "Admin Console." ?Here you will find a slit of your devices, their status, and their TailScale IP address.



Alan
 

From any PC, also running and logged into Tailscale:

In a web browser, enter the Raspberry Pi's Tailscalale address, port 1880. ?And a /ui at the end to go to the dashboard.

Or, id you are local, with both PCs on the same subnet, just use the IP address of the Raspberry Pi.

For example:

100.4.3.5:1880 ? goes to the Node Red Editor
100.4.3.5:1880/ui ? goes to the Node-Red Dashboard.

I don’t believe TailScale passes the broadcast packets from the radio.?

?Alan, I got it to work. Thanks for your great help. I needed to convert the 192.168.... address to the tailscale-generated PI address 100.10...as per your example.?

Next challenge will be to see if I can get FlexRadio 6400 to work using tailscale. SmartLink doesn't work because the router at the remote site doesn't allow port forwarding.
