Roku ECP Client

This is a go port of the Roku ECP Client I wrote in Ruby.

TUI Client Usage

Install then run the client

$ go install github.com/shreve/go-roku/cmd/roku

$ roku

This runs an interactive remote control program. By default, it scans the network and connects to the first Roku device it finds. If you'd prefer to hard-code the address, use the environment variable $ROKU_HOST.

Here are some of the key bindings

Key	Command
arrow keys	navigation
h/j/k/l	vi-style navigation
ctrl+up/down	volume up/down
ctrl+left/right	toggle mute
space bar	play/pause
asterisk	info/options (asterisk button on physical remote)
esc	back/exit
backspace	back/exit
enter	select
ctrl+q	power off
q	quit the remote app
ctrl+c	quit the remote app
o	open app (search interface)

Library Usage

Create a client for a Roku device by passing it's IP to Connect. If you don't know the IP, you can search the network for it with Discover

import "github.com/shreve/go-roku/roku"

var client roku.Client
host := os.Getenv("ROKU_HOST") // 192.168.0.100
if host == "" {
    client, err = roku.Connect(host)
} else {
    client, err = roku.Discover()
}

Once you have a client for a device on the network, you can access the ECP API via various helper functions.

// Turn up the volume for one second
client.Keydown(roku.VolumeUp)
time.Sleep(time.Second)
client.Keyup(roku.VolumeUp)

// Press the power button
client.Keypress(roku.PowerOff)

// Print the name of the device
info := client.DeviceInfo()
fmt.Println(info.FriendlyDeviceName)

// Print the name of the currently running app
app := client.ActiveApp()
fmt.Println(app.Name)

// Launch last app on the list
apps := client.Apps()
client.Launch(apps[len(apps)-1].Id)

Todo

• Allow retrying discovery rather than quitting in place

Wishlist

• Add help screen to app
• Better reporting in app
• Onscreen keyboard tool
• Create MPRIS daemon to allow controlling remote device with media keys
