I am developing an iOT system for my school project.

I have this setup with a DHT11 Temp/Humidity Sensor and a Raspberry-Pi(with Node-Red)

I am able to get data from the sensor by using Nodes on Node-Red ,and I can send those data to Xively.

The Question is I want to display the data from Xively on a free web dashboard.(Freeboard,etc.)

(I have written some C# pages to connect with Xively to activate/deactivate the sensor and view the statistics on my laptop.) I am able to convert the sensor's data to JSON or XML through Node-Red.

There are two solutions to my problem.

  1. Connect Freeboard with Node-Red on your device

  1. Connect Freeboard directly with a datasource (Xively, Local-Harddive ,etc)

(For the second method, I guess there's a bug in Freeboard where the value is not updated regularly. Link to my Issue request on Github : https://github.com/Freeboard/freeboard/issues/55 I will update about this matter ASAP.

Update : Freeboard have solved this issue.
