Distributed Raspberry Pi running Node Red #basic-training-sessions

 

I would like to have a distributed raspberry pi system with one runing the dashboard. For my station I woud have raspbery pi¡¯s talking to my Setppir, rotor, and antenna switch, then send that back to the raspberry pi in my station. ?Then I only need a network cable to the between the tower and station. ?

Now my question is do you need node red running on both Raspberry pi¡¯s. If so what do I run on the remote one. ?

Hi Tim,

Are the SteppIR, rotor controller, and antenna switch all located at the tower? Do you have anything else in the shack that needs to be connected to Node Red (not including network)?

If so, then you don¡¯t need a Pi in the shack, just access the dashboard over the network.?

If you need to plug in equipment into a Pi at each end then Node Red on both, send info to and from tower Pi to shack Pi via MQTT. Have shack Pi present dashboard via web access.

I do that now.?

At one end, run Node-Red, with the connection nodes (serial and TCP).? At the shack, run the full dashboard.

Connect via ethernet?TCP using a MQTT broker (like mosquitto?running on one of the Raspberries).

I also use the same for operating remote GPIO based relay boards.

Here is a screenshot of an example?where I use a remote Node-Red to connect to my SteppIR controller.? You can see the MQTT nodes to send the data packets.? Also, I always trigger the device, at the COM connection, for the periodic update packets.

Alan,

Thank you and now do you connect to your STEPPIR? ?I jsut picked up a 3 element one and with a rotor and antenna switch I am hoping a RS-232 to usb will work for the STEPPIR. ?

Also, I will look up MQTT for the com link. ?Looks like i have something new to learn.?

Lower DB9 connection.

FTDI chip based serial to USB with a null modem cable.? Be sure to use an authentic FTDI based cable for trouble free operation.

My SteppIR flow is in the group file section.

Dave,

I'm putting it together now, the tower goes up in the spring. ?I also want to control the radio, amp, and tuner in the shack. That looks easier than discreet relays for the antenna switch.?
