Remote operating and Node Red

I never, or not often, shut down the 12VDC supply to the Flex.  I believe this is the "Flex" preference (others can jump in here).   

I monitor the amp draw to the Flex and if you want to know the "boot status", you could use that to see when the Flex boots down.  Here are some typical values I see:

- 12 VDC off:   0 amps
- 12 VDC on, but not booted up;   0.5 amps
- 12 VDC on, booted up:     1.8 amps
- 12 VDC on, booted up, transmitting:  depends on the power level selected.

I am sure you could use the Flex Server API commands to ascertain the radio status.  One idea is to use the UDP-VITA49  broadcasts as an indicator.    Whenever the Flex has power, booted or not, it is doing the UDP-VITA49 broadcast.  A few nodes to detect the "absence" of the broadcast, will give you something you can work with.   Point a Node-Red UDP listener to port 4992 and you will see the broadcasts.

On second thought, the lack of UDP broadcast would not tell you boot up or boot down, only no 12 VDC.

I input the amps to my Node-Red Dashboard.  That seems your best solution to know boot status.

Hello, can anyone help me with the interface between 4992 and 4991 and Node-Red? I have already been able to implement individual values according to the specifications here in the forum. I would like to be able to see whether the Flex has been connected and which client is currently accessing it. Current voltage, PATemp, SWR, RFPower should also be displayed.
Since the Flex can only be reached remotely and there is a RaspberryPi already in use for controlling the power supply and antenna switch, I wanted to expand this node.
Everything works via FRStack and the corresponding RadioStream - but I don't have a Windows PC at the remote location.

I would be happy about new ideas. Stay healthy.

And....for the Flex meter data, Flex includes the actual data embedded within the VITA49 CODEC.   Decoding this CODEC is beyond my Node-Red abilities.

Mark of FRStack came to the rescue.  On the FRStack Options page, you can set up UDP broadcasts of the  Flex meter data.   Here is a flow I made for using the FRStack UDP Meter data, within Node-Red.

Hi Alan, thanks for the flows. It seems as if I have to operate FRStack directly at the remote location in order to realize all my wishes. The processed FRStack stream is very, very good.

Thanks for the quick help.

Hi Mike:

Could you send me a copy of your SteppIR Node-Red Flow?

I am preparing to install a Stepp IR Vertical.....in preparation for that PG-XL.

Neal;

Regarding font size.   Add your desired font information formated like this;    <font size = 10px color = red>   in front of the label text.   Here is a screenshot of an example where I adjusted the font for the "Value".   You can do the same for "Label", or any other text you want to modify.

I would love to do this , looks hard, I have windows 10 working great with UDP relays and  all remoted  . via  PSTrotator and  SPE amp. 

Michael,

I saw the mention of NodeRed in the video you posted about your remote station. This section of the forum is like drinking from a fire hose! I have a million questions more or less but a couple of simple ones to start:

1. Which of the KMTronic web switches are you using?
2. Is your switch connected right on the LAN or is it attached via USB or serial to one of the Raspberry Pi computers?

I was able to add my amp to the mix today. 

Tim, if you have a million questions, and want to save some hours of reading, we should talk on the phone to get you kick-started. My email is good on QRZ.com. N6YFM. At. A R R L. Dot. Net Neal
