Watch: Getting Started with Raspberry Pi kits
The video above unboxes and sets up a Raspberry Pi kit for Node-RED duty. Below we map the fastest setup paths and the first three flows worth building on any kit.
Scope note: this guide covers setup and first flows. Still picking hardware? The kit-selection guide compares four starter kits, and the written kit guide covers the full picture.
Quick answer: Flash Raspberry Pi OS, run the official Node-RED installer, then build three starter flows: inject-to-debug, a scheduled switch, and a dashboard gauge.
Each starter flow teaches one reusable concept — messages, triggers, and visualization — that every later automation builds on.
What is the fastest way to set up a new kit?
- Flash Raspberry Pi OS and boot the Pi (with monitor, or headless over SSH).
- Install Node-RED locally using the steps in the official local-install guide.
- Open the editor in a browser and deploy your first flow.
What does your first Node-RED flow look like?
Two nodes: an inject node firing on demand or on a schedule, wired to a debug node that prints the message. Deploying and watching messages travel teaches the core mental model — nodes passing message objects — described in the editor guide.
How do you add a dashboard?
Install the node-red-dashboard module from the palette (module page) and drop a gauge or chart onto a dashboard tab. Point any flow’s output at it and you have a live control panel in minutes.
When should you add MQTT?
The moment a second device joins the party. Run Mosquitto (mosquitto.org) alongside Node-RED, publish sensor readings to topics, and subscribe from your flows — it scales cleanly from two devices to two hundred.
Which setup path fits you?
| Path | You need | Best for |
|---|---|---|
| Desktop with monitor | Screen and keyboard | Absolute beginners wanting visual feedback |
| Headless over SSH | Network connection only | A hub hidden in a closet |
| Preloaded microSD kit | Kit with preloaded card | Fastest hardware start |

Frequently Asked Questions
Can the Pi run Node-RED 24/7?
Yes — with a proper power supply and some cooling it is the canonical always-on Node-RED host.
Do I need to write code?
No. Wiring nodes visually covers most needs; code stays optional.
How do I back up my flows?
Export flows as JSON from the editor menu and keep copies — the export/import workflow is part of the editor.
What comes after the first three flows?
Sensors, MQTT devices, and eventually a Zigbee coordinator — each adds a new input family without changing the fundamentals.
