Homie server

(broken)

A Web server for Homie, an MQTT convention for the IoT. Built with Node.js. The project is currently in alpha.

Features

• Simple but efficient dashboard
• OTA updates
• Compatible starting with Node.js v0.12 (0.10 might work, but it is not CI-tested)

Installation

npm install -g homie-server

Usage

The Homie server can only be started using the CLI interface. Start Homie by calling homie. You can optionally provide a --dataDir argument that will be used to store the Homie data. By default, this directory is located at <home directory>/.homie. You can also configure the HTTP server serving the UI with --uiPort, else it defaults to 80. Finally, you can change the log level of the output with the --logLevel parameter followed by the minimum log level to show (0 for fatal, 1 for error, 2 for warning, 3 for info, 4 for debug).

Configuration

Three files define the behavior of Homie, and are all contained in the data directory:

1. The config.yml file. It contains some configuration like your MQTT broker address.

mqtt:
  url: mqtt://127.0.0.1:1883
  clientId: optional client ID
  username: optional username
  password: optional password

1. The infrastructure.yml file. This file contains the representation of your Homie devices. You can also group devices there.

devices:
  - id: abcd0123
    location: Marvin's room
    nodes:
      - type: shutters
        id: shutters
        name: Shutters
  - id: efab4567
    location: Mathys's room
    nodes:
      - type: light
        id: main
        name: Main light
      - type: light
        id: bed
        name: Bed light
 
groups:
  id: first-floor
  name: First floor
  devices:
    - abcd0123
    - efab4567

1. The ota/manifest.yml file. It contains a definition of the firmwares for your devices, like so:

firmwares:
  - name: light-firmware
    version: 1.0.0
    devices:
      - marvin-lights

For this example manifest, you would put the firmware binary in ota/firmwares/light-firmware.bin, otherwise, OTA won't be handled. You can update the manifest while Homie is running, it will be hot loaded.

Contribute

Contributions are very welcome!

To work/start the git Homie version, just run npm run dev. This will build the public directory, and watch for changes in the app folder. To start the server, run npm start. The GUI will be listening on port 3000.
