Usage Example

with Hub IP 192.168.0.50:

const util = require('util');
const HarmonyHubWS = require('harmonyhubws');
const IP = '192.168.0.50';
 
let harmonyHubWS = new HarmonyHubWS(IP);
harmonyHubWS.on('online', () => {
    console.log('connected to hub', IP);
    //request config
    harmonyHubWS.requestConfig();
});
 
harmonyHubWS.on('config', (config) => {
    //be careful, config could be very big!
    console.log('config', util.inspect(config,false, null, true));
    //request hub state
    harmonyHubWS.requestState();
 
    //if there is a device press first button of device
    if (config.device.length) {
        let device = config.device[0];
        if (device.controlGroup.length && device.controlGroup[0].function.length) {
            console.log('pressing key', device.label, device.controlGroup[0].function[0].label);
            harmonyHubWS.requestKeyPress(device.controlGroup[0].function[0].action);
        }
    }
 
    //if there is an activity start it
    if (config.activity.length) {
        let activity = config.activity[0];
        console.log('starting activity', activity.label);
        harmonyHubWS.requestActivityChange(activity.id);
    }
});
 
harmonyHubWS.on('state', (activityId, activityStatus) => {
    console.log('state', activityId, activityStatus);
    //if an activity is started turn it off and close client
    if (activityStatus === 2) {
        console.log('activity started, turn off', activityId);
        harmonyHubWS.requestActivityChange('-1');
        harmonyHubWS.close();
    }
});
 
harmonyHubWS.on('offline', () => {
    console.log('lost connection to hub', IP);
});

new HarmonyHubWS(ip, watchdog)

Returns the state object of the robot. Also updates all robot properties.

• ip: string - IP of your Harmony Hub
• example:

const HarmonyHubWS = require('harmonyhubws');
const IP = '192.168.0.50';
 
//start client without automatic connection handling
let harmonyHubWS = new HarmonyHubWS(IP, false);

Functions

requestConfig()

Asks Hub to send Config. To retrieve config use event config.

requestState()

Asks Hub to send current state. To retrieve current state use event state.

requestActivityChange(activityId)

Asks Hub to start activity with ID activityId. Results in multiple state events, activityState will be 2 when the activity is completely started.

• activityId: number|string - ID of the activity you want to start, use '-1' (string!) to turn off any activity. To retrieve activity IDs see requestConfig.

requestKeyPress(action, hold = 'press', delay = 100)

Asks Hub to press a device key.

• action: string - whole action string (deviceId, keyId, type) as retrieved from config.
• [hold]: string 'press' or 'hold' - defaults to press, hold is a long press for ~250ms, if you want to hold longer you need to request hold repeatedly.

or

requestKeyPress(deviceId, keyId, type = 'IRCommand', hold = 'press', delay = 100)

• deviceId: string - ID of the device you want to control. To retrieve device IDs see requestConfig.
• keyId: string - ID (name) of the key you want to press. To retrieve key Ids see requestConfig.
• [type]: number - defaults to IRCommand. To retrieve key types see requestConfig.
• [hold]: string 'press' or 'hold' - defaults to press, hold is a long press for ~250ms, if you want to hold longer you need to request hold repeatedly.

Events

.on('online', () => {})

Fired when connection to hub is established.

.on('offline', () => {})

Fired when connection to hub is lost.

.on('state', (activityId, activityState) => {})

Fired when hub sends its current state.

• activityId: number|string - ID of current activity, '-1' for powerOff.
• activityState: number - state of current activity, where
  • 0: off
  • 1: starting (hub blocked until activityState is 2)
  • 2: started
  • 3: stopping (hub blocked until activityState is 0)

.on('config', (config) => {})
