The SteppIR controller is most likely a DTE com port while the Pi is a DCE. You will probably need a null modem adapter.

OK

I removed the TCP Request Node and routed the Inject Node to the HEX to string Converter node. Test that with a simulated KENWOOD serial frequency command string <FA00007150000> and it outputs the desired relay command. in the DEBUG window...So far so good

Next I replace the INJECT node with a Serial-In Node. After the proper baud rates(4800-N-8-1), etc the node registers "Connected". I take the serial cable from a known working connection ( Radio to Stepp-IR controller) and attach it to the USB serial connection on the R-PI. My USB/Serial dongle has a series of LED's in it that allow to me monitor activity. When the frequency is changed the RXD line flickers with activity so I am pretty sure traffic is flowing in to the serial in node but apparently nothing coming out to the HEX/String converter

What did I miss??

Think of Node Red as a flow chart. Input data, pass it to next node, do something with dat, pass it along, do something, etc.

Do Google searches for example Node Red flows, especially for Home Automation. They will give you an idea on how Node Red works. It is very easy once you start playing around. There are plenty of flows in the file section which will give ideas on how to accomplish a number of things.

I finally found a good beginners tutorial <Workshops.opto22.com> which helped me a lot. Though I usually dislike U-Boob videos this kid's Midwest accent was flat enough and his voice had enough bass for my 160M static damaged ears to understand

Thanks again as this sounds exactly what I was going to try and do

?Hi Randy

I finally got this going. Took me a bit to work out that with my ERC-M set up to use GS-232B, I needed to change some nodes so that the trim and? parsing used + not AZ=

Anyway, working now and looks good. I also added a graphic centred on VK1 so all the directions had to be changed too.

Double click on the Antenna Button, you want to changes. ?Revise the "Label" as shown below.

Some other buttons have an in-line configuration function for the labels, but not so in this case.

Hi all,

I have been looking how to change the antenna name on the HF-Auto flow. The default port one is showing as Dummy load on the UI page.

I must be missing a setting in the flow to change this

Thanks,

I used a Webrelay and then installed a 25 amp contractor in 4 by 4 handy box with SO 10 ga in and out. 12 volt coil so on my other 12 volt devices had it anyway!

?I need a web based switch to turn my amp on and off with. Any ides would be great.
