Re: K3NG arduino-based rotator interface via Pi4 with NodeRed?

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.

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 :... but where do I find this specific address in the flow so I can browse to it?

?

Thanks,

?

Chris

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 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 .
