News How to Use Raspberry Pi Pico W With Node-RED

[Admin]

The Raspberry Pi Pico W is cheap enough to forget about it and in this project we do just that. We build a sensor platform from the Pico W and send live data to the cloud using Node-RED to create our own web application.

Do you HAVE to send the data to the cloud if the devices are both on the same local WiFi network?
I wanted to use this type of thing to have Pico Ws read various boat sensors (tank levels, temps and stuff) and send that data to a central Raspberry Pi 4. The issue with how you have this is that when we're out sailing, we're often out of cell range, so the cloud isn't an option.
Given that I can already send simple data from the Pico W via a self-generated webpage, I was wondering if it could be streamed via maybe a particular IP : Port straight to Node Red on the central Pi 4, which is already reading marine NMEA data and sending it out over WiFi using Signal K.
