A node module for interacting with an Apple TV (4th-generation or later) over the MediaRemoteTV protocol.
node-appletv
is a node.js
implementation of the MediaRemoteTV protocol which shipped with the 4th-generation Apple TV. This is the protocol that the Apple TV remote app uses, so this should enable the creation of an Apple TV remote app for various platforms. It can also be used in a homebridge
plugin to connect Apple TV events to HomeKit and vice versa. node-appletv
can be used as a standalone command line application, or as a module in your own node app. Keep reading for installation and usage instructions.
# Install
$ npm install -g node-appletv
# Display built-in help
$ appletv --help
The appletv
cli supports several commands, such as:
pair
: Scans for Apple TVs on the local network and initiates the pairing process
command <command>
: Execute a command on an Apple TV (play, pause, menu, etc.)
state
: Logs state changes from an Apple TV (now playing info)
queue
: Requests the current playback queue from an Apple TV
messages
: Logs all raw messages from an Apple TV
help <command>
: Get help for a specific command
$ npm install --save node-appletv
node-appletv
makes heavy use of Promises. All functions, except for the observe functions, return Promises.
import { scan } from 'node-appletv';
return scan()
.then(devices => {
// devices is an array of AppleTV objects
let device = devices[0];
return device
.openConnection()
.then(device => {
return device.pair();
})
.then(callback => {
// the pin is provided onscreen from the Apple TV
return callback(pin);
});
})
.then(device => {
// you're paired!
let credentials = device.credentials.toString();
console.log(credentials);
})
.catch(error => {
console.log(error);
});
import { scan, parseCredentials } from 'node-appletv';
// see example above for how to get the credentials string
let credentials = parseCredentials(credentialsString);
return scan(uniqueIdentifier)
.then(devices => {
let device = devices[0];
return device
.openConnection(credentials);
})
.then(device => {
// you're connected!
return device.sendKeyCommand(AppleTV.Key.Menu);
})
.then(device => {
console.log("Sent a menu command!");
})
.catch(error => {
console.log(error);
});
The uniqueIdentifier
is advertised by each Apple TV via Bonjour. Use an app like Bonjour Browser to find it. The identifier is also the first value in the string value of the Credentials
object.
node-appletv
is written in Typescript. Edit files in the src
directory and then run npm link
to clean, build, and create the symlinks to use the library and cli.
node-appletv
would not have been possible without the work of these people:
- Jean Regisser who reversed the protobuf spec of the MediaRemoteTV protocol
- Pierre Ståhl who implemented the protocol in Python
- Khaos Tian for reversing the HomeKit protocol which also uses SRP encryption
- Zach Bean for implementing the HAP client spec
