Hi everyone,
I’d like to share a small hobby project we recently built using Node-RED. The idea was to create an air quality dashboard that collects data from a BLE sensor and visualizes it in real time.
For this, we used a BLE USB dongle (BleuIO) to handle the Bluetooth Low Energy communication, together with Node-RED for the data flow and dashboard. The project covers scanning for the sensor, retrieving the air quality data, and presenting it on a simple UI.
We documented the steps in detail here: Using BleuIO with Node-RED to Build a BLE Air Quality Dashboard - BleuIO - Create Bluetooth Low Energy application
Hopefully this is useful for anyone interested in combining BLE devices with Node-RED. I’d be happy to answer any questions or hear suggestions for improvements.
