  title: Roku External Control Protocol (ECP) Apps Query API
  version: '1.0'
  description: 'The External Control Protocol (ECP) is an HTTP-based API exposed on port 8060 of every Roku

    streaming device on the local network. It enables third-party applications, mobile remote-control

    apps, automated testing systems, and home-automation hubs to discover Roku devices via SSDP,

    inject simulated remote-control key presses, launch installed apps with deep-link parameters,

    query device state, and retrieve diagnostic information.


    The protocol is plain HTTP/1.1 (no TLS) and is intended for trusted local-network use only.

    Most control operations require the user to enable "Control by mobile apps" on the device.

    Additional diagnostic endpoints (chanperf, sgnodes, registry, etc.) are gated behind Roku

    Developer Mode.
