One of the greatest features on [BlueOS 1.1](https://discuss.bluerobotics.com/t/blueos-1-1-0-release/14931) is the possibility to install extensions and extend the funcionalities of the system.
**Node-RED** extension is one available in our store. There you can read data from serial ports, receive and send mavlink messages, write to a file and much more!

You can also create your own dashboard to visualize the information or send messages to vehicle or ground station.
Flow used in this example: [example.json](https://discuss.bluerobotics.com/uploads/short-url/kRrxfzN9eXTLFdmn2ya1ghvOjAg.json) (1.4 KB)
> Note: You need to install in node-red the following plugins: `node-red-contrib-web-worldmap`, `node-red-dashboard`, `node-red-node-serialport`

Great news!
I want to use a joystick to move the ZOOM on my IP camera.
Can I use Red-Node to get custom\_1 input?
The IP camera can be configured for Zoom at http put.

Hi @Itaru,
You may want to try this extension:
> **[node-red-contrib-onvif](https://flows.nodered.org/node/node-red-contrib-onvif)**
>
> A Node-RED node that interacts with ip cameras using the ONVIF protocol

Thank you very much.
I understood that there is also an onvif extension.
What I want to know is how to write mavlink and message.
How do I receive custom\_1 input from joystic?

@patrickelectric are you able to share the Json file for the entire example flow and not just the graph node?

@Itaru thanks, this is perfect - so looking forward to making use of this functionality. Great job on BlueOS, the mavlink rest api and Node-Red extension.

Is the original flow available somewhere? I am looking for info about the Websocket out part (bottom right part). This can be use to send custom command to the pilot rigth?
