HAP Router

A Middleware HAP Router for bringing HomeKit functionality to your Home Automation.

HAP Router is a middleware NodeJS server that allows you to take advantage of Apples HomeKit technology, and bring it in to your automation ecosystem.

This is achieved by creating simple, software based accessories, that can be enrolled into HomeKit.

The difference however, compared to most implementations of this kind, is that the events that occur on them are directed (or routed) to a transport of your choice.

These transports can be a UDP broadcast, a message sent to an MQTT broker, sent to Node Red or any other automation platform.

The accessories have also been created for you, and you simply select the type of accessory you wish to create
and set their associated information.

Transports are the medium, in which the event is travelled. By default, the following transports (or routes) are as follows:

• HTTP
• UDP Broadcast
• File
• MQTT
• Websocket
• Console (Mainly for testing)

When I say 'by default' - what I mean here, is that you can develop your own route modules.

The transport/route will receive the following JSON payload.
There are 3 event types: characteristicUpdate, pairStatusUpdate, identifyAccessory

pairStatusUpdate

{
  accessory: {
    AccessoryID: '8D6497BC70A1',
    AccessoryType: 'Fan',
    AccessoryName: 'My Fan',
    AccessorySerialNumber: '2ND2PB12EQO3',
    Bridged: false
  },
  route: {
    Name: 'Output To Console',
    Type: 'Console Output'
  },
  eventType: 'pairStatusUpdate',
  eventData: true
}

identifyAccessory

{
  accessory: {
    AccessoryID: '8D6497BC70A1',
    AccessoryType: 'Fan',
    AccessoryName: 'My Fan',
    AccessorySerialNumber: '2ND2PB12EQO3',
    Bridged: false
  },
  route: {
    Name: 'Output To Console',
    Type: 'Console Output'
  },
  eventType: 'identifyAccessory',
  eventData: true
}

characteristicUpdate

{
  accessory: {
    AccessoryID: '8D6497BC70A1',
    AccessoryType: 'Fan',
    AccessoryName: 'My Fan',
    AccessorySerialNumber: '2ND2PB12EQO3',
    Bridged: false
  },
  route: {
    Name: 'Output To Console',
    Type: 'Console Output'
  },
  eventType: 'characteristicUpdate',
  eventSource: 'iOS_DEVICE',
  eventData: {
    characteristic: 'RotationSpeed',
    value: 62
  }
}

If you're a Home Automation Enthusiast, or just a tinkerer, Hap Router allows you to explore Homekit, and build with it.

Nice! how do I get started

The server is managed by a gorgeous looking Web User Interface (if the above images haven't already suggested so), It is a breeze to use, and at the basic level you:

• Create a Route (Routes can be used by more than 1 accessory)
• Create an Accessory
  • Contact Sensor
  • Air Quality Sensor
  • Intruder Alarm
  • Multisensor - Combinations of:
    • Motion
    • Lux
    • Temp
    • Humidity
  • Power Outlet
  • Basic On/Off Switch
  • Fan
  • Lock
  • Light Bulb
  • Smart TV
  • Garage Door Opener
  • Thermostat
  • Smoke Sensor
  • Leak Sensor
  • CCTV Camera
• Enroll the device in HomeKit.
• Have Fun.

Devices can be 'published' in 2 ways:

• Attached to a bridge (HAP Router can also act as a Bridge)
• Exposed as a seperate device.

If you have Enrolled HAP Router in your HomeKit environment as a bridge, then any accessories attached to this Bridge, will be seen when published. else, you enroll the accessory as a separate entity.

Manipulating accessories using non apple devices.

HAP Router has a web based API, as well as an MQTT client built in.
The web API uses BASIC HTTP Authentication, and the login details are the same as the management UI.

Method	Address	Description
GET	/api/accessories	Lists all accessories and there current characteristics
GET	/api/accessories/{{AccessoryID}}	Same as above but for the identified accessory
POST	/api/accessories/{{AccessoryID}}	Sets characteristics for the identified accessory

To turn the fan accessory on at full speed using the web API, you will:
Send a post request to: http://{{IP ADDRESS}}:7989/api/accessories/8D6497BC70A1
And include the following POST body (with a type of application/json)

{
  'On': true,
  'RotationSpeed': 100
}

If you have enabled the MQTT client in the UI, the same message will be sent.
Just ensure the topic of the message ends with the Accessory ID.
By default the subscribed topic is HAPRouter/IN/+

Command line arguments

Argument	Description
reset	Completely resets HAP Router to a default state
installmodule {{Name}}	Installs the specified route module from NPM
passwd {{Username}} {{Password}}	Set the UI and API login information

Installing and Running

Make sure you have Node >= v14.14.0 installed

Simply install via NPM npm install hap-router
to run the server just call node HAPRouter.js

Credits

HAP Router is based on the awesome HAP-NodeJS library, without it, projects like this one are not possible.
