This document describes RumahPintar, an Internet of Things mobile app for controlling devices and monitoring sensors in a smart student housing environment. The app uses NodeJS and socket.io to enable real-time communication between Raspberry Pi devices, a virtual private server, and Android mobile apps. Websockets allow for fast, simple event-based communication compared to conventional HTTP requests. An early prototype demonstrated controlling a lamp and monitoring temperature and humidity from a DHT11 sensor. The source code is available on GitHub under the MIT license.

2. Goals

Controlling devices : bulb lamp, washing
machine, television, etc. Check their status,
whether it is on or off. Save more energy.

Monitoring : temperature, humidity, image,
video, check for gas leak, smart alarm, etc.
More secure and controlled environment.

Almost everything in your hand

3. Technology we use

NodeJS


Internet of Things framework, nf-iot-*

Native socket.io (for Android) for realtime
communication

Raspberry Pi <---> VPS <---> Mobile Apps

4. Why websocket instead of
conventional http request (rest API)

The simplicity of event and emit

Fast

We could learn new thing

How about COAP?

5. Early Prototype

Controlling a lamp, switch on and off

Monitoring a DHT11 sensor : temperature and
humidity
