Node Red Contrib Homekit Docker

Abstract

1. Introduction

Node-RED-homekit-docker is a Node-RED based project with support for homekit. It is based on the official Node-RED Docker images with the necessary tools and npm module node-red-contrib-homekit-bridged installed to run homekit within a docker container.

Node-RED-homekit-docker is supported by a manifest list, which means one doesn't need to specify the tag for a specific architecture. Using the image without any tag or the latest tag will pull the right image for the architecture required.

longer supported. Use a 64-bit OS on supported Raspberry Pi hardware, or stay on an older image tag that still contains the required 32-bit architecture.

2. Objective

Node-RED-homekit-docker is a Node-RED based project with support for homekit.

This project demonstrates how JavaScript, Docker, Raspberry Pi can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Node.js (LTS) and npm
• A modern web browser
• VS Code or any code editor
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/NRCHKB/node-red-contrib-homekit-docker.git
cd node-red-contrib-homekit-docker

1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
4. The Docker daemon streamed that output to the Docker client, which sent it

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a mobile dashboard using Blynk or Firebase
• Store readings in a cloud database for history charts
• Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
