Temp and voltage

in FLEX-8000 Signature Series

Seems that the 8x00 is aware of its own internal temp and supply voltage. I see that when connecting via smartsdr software. Is there a way I can easily access this data from a raspberry pi or Arduino which is at the site sitting alongside the 8400? Via USB or API or some way?

My setup will be..:

  • 8400 will be a 2 hr drive from my place
  • Using maestro C for the shack end.
  • No 'computer' involved (locally or remotely)

    load Node Red server on the Pi with requisite nodes then load the Flex Radio flow. It contains voltage, fan and temp readings.

    I'm seeking to make the setup as simple as possible at the remote site. I may go down the node red path at some point (appreciate the idea, had forgotten about that tbh!) but for the moment just seeking a pointer on how to get this data simply, directly, if possible. I can easily make an API call from python on the Pi etc.

    Just had a look at node red...does it just use CAT commands to get all of its data?

    Im new to CAT but this looks good if so!

    Node-RED flows typically use the TCP API (FlexRadio nodes) or the SmartSDR API (FRStackWebApi). You can fetch data with CAT but it does not make sense as it is limited compared to the APIs.

    SDR monitor is a nice little app that connects to your flex and gives a small window for temp and voltage.

    This does need a PC so node red is probably your best and easiest bet, the flows are already written for you so its just a case of some config to get up and running.

    Thanks W8BE.. exactly the pointer I am after!

    Give NodeRed a try. It isn't as hard as you think and it really opens the door to a lot of options.

    Couple that with TailScale for the VPN stuff and will have a lot of growth options.

    I use KMTronic Temperature sensors and they are invaluable as they are also web based.

    This is my very 'dated' control console running on a PI4. Check out the temperatures.
