Send Signal K data to another Signal K server

[goosevlc]

Hello, I am using a system composed of Openplotter, with inputs through Signal k, and temperature sensors through Node red for motor control, using a raspberry Pi 4.
I have installed the Venus large system on another raspberry pi 3, which includes another Signal K server.
I have installed the Venus system on another Pi for touch screen control.
Until now, using Signal K's Venus plugin, it collected the data it sent to Node Red.
Connecting the data now to the Venus software on the raspberry Pi 3, I don't have the data on Signal K on the raspberry Pi 4.
I don't know how to do it, could the data from the raspberry Pi 3 be sent to the raspberry Pi 4, through the ship's internal Wi-Fi network using the Signal K servers?
Is it necessary to change the Signal K (3000) port on any raspberry? And if it is, how is it done?
I hope I have explained myself.
Thanks in advance.

Sorry, I have trouble understanding your setup. Please list explicitly what inputs and components are on which Pi. Like

Pi4 (OpenPlotter)

• Signal K
• Node-RED (standalone or Signal K plugin?)
  • temperature sensors
  • motor control

Pi3 (Venus OS)

• touch screen
• Signal K

When you say Connecting the data now to the Venus software what data are you talking about and what do you mean with "Venus software"?

Hello, sorry for my explanation, I'm trying to explain myself.

Raspberry Pi 4 (4gb):

• Openplotter 3
• Opencpn, I receive data from signal k
• Signal K with input data:

1. Ais
2. GPS
3. I2c (pressure, humidity and cabin temperature)
4. Vedirect-serial-usb (so far collecting information from my solar charger)
5. Seatalk 1 (wind, depth, HDM)

• Node Red (signal k webapp) where I receive the data from signal k and the data from 10 temperature sensors (engine, batteries, hot water)

Raspberry Pi 3 (2 Gb) in test:

• Victron Venus operating system for raspberry. I have the large version installed, where signal K and node red are installed.
• Raspberry 7 inch touch screen
• Performing tests with relays

Now receiving the data from Victron through the Raspberry Pi 3, I do not have that data on the Raspberry Pi 4, where I graphed it in Node Red and sent it to Grafana and InfluxDb.

My question is, is it possible to send data from the raspberry Pi 3 to the raspberry Pi 4 through Signal K? If so, how is it done?
Or if any other way to send the data.

The two raspberries are connected to the boat's Wi-Fi network.

it is understood? It is difficult to explain it with my basic knowledge.

Thank you

On your PI4, create a "Data Connnection" with Type Signal K, and Source WebSocket. Enter the ip of the other pi, port 3000. And choose "Map self to local self".

Thank you very much, I already have it working!!!

I had been thinking for a while about how to communicate two signal k servers.

Now I receive the data from the Venus operating system on the raspberry pi 4, where I collect the information from the Victron equipment.

On the contrary, I have also done it, from the Raspberry Pi 4, I have tried sending to the Venus operating system, and it also receives the data.
What I need is to see how this data is read by the Venus system, such as the temperatures of the batteries (1w sensors)

Thank you
