I use DLI switch that energizes a Packard 340B 3 pole 40 amp relay. It has a 120 volt coil so you just need an open spot on your switch. I have two of these and use one for an Alpha 9500 and one for a

I use one of these IP relays to control 2 higher current relays similar to the one Mike has shown. Amazon.com: LAN Ethernet Controller Module, TCP/UDP Controller Module with 2-Way Relay Board Delay

HI ..... Help from anyone who is using k3ng-rotor whit the SER2NET.... still fighting to get the rotor flow to work....... On output-5 I can see the command I send to my rotor, if I ned the Beam dir I

I built my own switch that is operated by 12V using a Potter and Brumfield DPST relay. I then switch the 12V to this relay with my KMTronic relay board. This is how the commercial world does it. They

I picked up a Suraielec model UBTW01B from Amazon which I can control through Alexa and the Smart Home app on my phone. Having a single pane in NodeRed to control all of the devices would be nice. My

I figured it out. Had to refresh myself on how the Dashboard layout works. Cheers.

I have the Denkovi USB 8 Relay board.? I'm using it to control my K9AY Loop System box. The free software works with MQTT. Steve WA8Y

Frank, I really like your layout and am trying to reproduce it.? Can't quite figure out the spacer(s).? Can you post it?? Thanks.

I looked a while back to program an interface (in Delphi) and I swear they do not want anyone to sell software except theirs! I looked at their free "sample" and did not care for the UI and put mine

Hi Harry, While there are many relay boards out there, actually have the LP Remote extension board (the one with the 16 relays on it), which uses 2 8-port MCP23008 i2c port expanders, which drive a

Thanks Alan for the info. So far all I have done with Node-Red is down load it to my win 10 machine. I have connected to the palette and watched a utube video which described the process for creating

Harry There are several relay board types, and everyone has a favorite. My favorites are the DLI Relay switches and the GPIO pin-based relay boards. Both have flows posed on this site. You asked about

Hi...I am new to this group and Node Red. Currently I am using a product called LP-REMOTE (N8LP product) to control up to 16 relays. It is starting to have problems and I would like to replace it. So

Good Luck! I run my main shack dashboard on a Debian mini-pc but it should work on the Pi4 as well. The biggest issues I had getting the flow working was the timing to get the 9500 streaming the

Thanks George, I’m building up a Pi4 to send to Hawaii where the 9500 is located. I’ll pick the TX frequency off my FlexRadio flow. I have to change a few things around with the rotor flow for the

One more comment. In the ARRL RTTY RU this weekend I found running with the 9500 much quieter than my PGXL! I generally set the 9500 to 1k out and only cranked it up to 1.5k if someone moved in on my

Here is a picture and the flow. I do have another version that I set up for rig 1 as I can configure my Node-Red dashboard for MS instead of SO2R. There are some extra nodes in the flow from

Thanks George. I have an idea on “fixing” the split issue. I’ll take a look at the flow and see if my idea will fly. 73 Dave wo2x Sent from my waxed string and tin cans.

Hi Dave, I have one. It’s integrated with N1MM UDP so it reads my rig frequency and changes to the correct band segment. It doesn’t work well split as it hunts between segments but I have it set

Nick, the Read Me node will have the flow version. The "Log" button starts a CSV (command separated value) log on the Node Red server logging the vdata returned form the SPE flows. I import the data
