HAS is a Homekit accessory server written in NodeJS which lets you create your own Homekit-enabled accessories on your computer, Raspberry Pi or everything else which can run NodeJS.

It provides you a rich and simple API to create your own servers, accessories, services and characteristic.

This project is based on Homekit accessory protocol(HAP) specification which you can find it here(Requires Apple developer account).

npm install has-node 

import * as HAS from 'has-node';

let config = new HAS.Config('NodeJS Fan', '82:E6:B6:63:BC:2C', HAS.categories.fan, __dirname + '/fan.json', 8091, '200-20-200');

let server = new HAS.Server(config);

//Fan
let fan = new HAS.Accessory(1);

let fanIdentify = HAS.predefined.Identify(1, undefined, (value, callback) => {
        console.log('Fan Identify', value);
        callback(HAS.statusCodes.OK);
    }),
    fanManufacturer = HAS.predefined.Manufacturer(2, 'Hamyar'),
    fanModel = HAS.predefined.Model(3, 'Model2017'),
    fanName = HAS.predefined.Name(4, 'Fan'),
    fanSerialNumber = HAS.predefined.SerialNumber(5, 'ABCDEFGHIJ'),
    fanFirmwareVersion = HAS.predefined.FirmwareRevision(6, '1.0.0');
fan.addServices(HAS.predefined.AccessoryInformation(1, [fanIdentify, fanManufacturer, fanModel, fanName, fanSerialNumber, fanFirmwareVersion]));


let on = HAS.predefined.On(1, false, (value, callback) => {
    console.log('Fan Status', value);
    callback(HAS.statusCodes.OK);
});
fan.addServices(HAS.predefined.Fan(2, [on]));

server.addAccessory(fan);

//server.onIdentify will be used only when server is not paired, If server is paired identify.onWrite will be used
server.onIdentify = fanIdentify.onWrite;

//Starts the server
server.startServer();

Configuration

let config = new HAS.Config(name, deviceID, category, configDir, TCPPort, setupCode);

Parameters:

• name: (string) Name of accessory.

• deviceID: (string) ID of accessory.

• category: (HAS.categories) Category of accessory.

• configDir: (string) Path of config file. Will be created automatically if does not exists.

• TCPPort: (number) Port of TCP server.

• setupCode (string) Accessory setup code(User will use this code for pairing).

Methods:

• config.getHASID(UUID): number: Maps UUID to persistent unique integer.

• config.resetHASID(UUID): Resets mapped integer for an UUID.

Server

let server = new HAS.Server(config);

Parameters:

• config: (HAS.Config) Config object.

Methods:

• server.startServer(): Starts the server.

• server.stopServer(callback?): Stops the server.

• server.addAccessory(accessory): Adds an accessory to server.

• server.removeAccessory(accessoryID): Removes an accessory from server.

Properties:

• server.onIdentify: ((value: any, callback: (status: HAS.statusCodes) => void) => void) This function will be used to identify the server.

Characteristic

let characteristic = new HAS.Characteristic(ID, type, valueFormat, isHidden, hasNotifications, hasValue, isReadonly, additionalAuthorization, valueUnit, description, minValue, maxValue, stepValue, maxLength, validValues, validRangeValues);

Parameters:

• ID: (number) ID of characteristic. Should be unique at service level.

• type: (string) Type of characteristic. Read HAP specification for more information.

• valueFormat: ('bool' | 'uint8' | 'uint16' | 'uint32' | 'int' | 'float' | 'string' | 'tlv8' | 'data') Data type of characteristic.

• isHidden: (boolean?) Whether or not this is a hidden characteristic.

• hasNotifications: (boolean?) Whether or not this characteristic supports notifications.

• hasValue: (boolean?) Whether or not this a write-only characteristic.

• isReadonly: (boolean?) Whether or not this a readonly characteristic.

• additionalAuthorization: (boolean?) Whether or not this characteristic needs additional authorization.

• valueUnit: (('celsius' | 'percentage' | 'arcdegrees' | 'lux' | 'seconds')?) Characteristic Value Unit

• description: (string?) Description of this characteristic.

• minValue: (number?) Characteristic Min. Value

• maxValue: (number?) Characteristic Max. Value

• stepValue: (number?) Characteristic Step Value (characteristic.value % characteristic.stepValue should be 0.)

• maxLength: (number?) Max. length of this characteristic(Only if characteristic is string or buffer.)

• validValues: (number[]?) An array of valid values.

• validRangeValues: (number[]?) characteristic.value >= characteristic.validRangeValues[0] && characteristic.value <= characteristic.validRangeValues[1] should be true.

Methods:

• characteristic.setValue(value): Boolean Sets the value of characteristic and returns result as boolean.

• characteristic.getValue(parse: Boolean = false) Returns value of characteristic.

• characteristic.onWrite: ((value: any, callback: (status: HAS.statusCodes) => void, authData?: Buffer) => void) Set this function to handle value write requests.

Service

let service = new HAS.Service(ID, type, isHidden, isPrimary, linkedServices);

Parameters:

• ID: (number) ID of service. Should be unique at accessory level.

• type: (string) Type of service. Read HAP specification for more information.

• isHidden: (boolean) Whether or not this a hidden service.

• isPrimary: (boolean) Whether or not this a primary service. Each accessory can not have more than one primary service.

• linkedServices: (number[]) Array of IDs of linked services. Linked services should be already added to accessory.

Methods:

• service.addCharacteristic(characteristic) Adds a characteristic to this service.

• service.addCharacteristics(...characteristics) Adds a group of characteristics to this service.

Accessory

let accessory = new HAS.Accessory(ID);

Parameters:

• ID: (number) ID of accessory. Should be unique at server level.

Methods:

• accessory.addService(service) Adds a service to this accessory.

• accessory.addServices(...services) Adds a group of services to this accessory.

Each accessory needs to have an information service with serviceID = 1.

Predefined

Instead of creating your own services and characteristics, you can use HAS.predefined.

let characteristic = HAS.predefined.characteristicName(ID, value, onWrite);

• Parameters are described in Characteristic section.

let service = HAS.predefined.serviceName(ID, characteristics, isHidden, isPrimary, linkedServices);

• Parameters are described in Service section.

You can find predefined items by looking at HAP specification or source code.
