MQTT addon for Kodi

Written and (C) 2015-16 Oliver Wagner owagner@tellerulam.com

Provided under the terms of the MIT license.

Overview

This is a Kodi addon which acts as an adapter between a Kodi media center instance and MQTT. It publishes Kodi's playback state on MQTT topics, and provides remote control capability also via messages to MQTT topics.

It's intended as a building block in heterogenous smart home environments where an MQTT message broker is used as the centralized message bus. See https://github.com/mqtt-smarthome for a rationale and architectural overview.

Dependencies

Build Status Automatically built addons can be downloaded from the release page on GitHub at https://github.com/owagner/kodi2mqtt/releases

Settings

The addon has multiple settings:

  • the MQTT broker's host name or IP address (defaults to 127.0.0.1)
  • the MQTT broker's port. This defaults to 1883, which is the MQTT standard port for unencrypted connections.
  • the topic prefix which to use in all published and subscribed topics. Defaults to "kodi/".
  • MQTT authentication and TLS settings
  • update frequency intervals
  • keyword filtering on content details, to prevent certain kind of content to be e.g. displayed in a SmartHome visualization

Topics

The addon publishes on the following topics (prefixed with the configured topic prefix):

  • connected: 2 if the addon is currently connected to the broker, 0 otherwise. This topic is set to 0 with a MQTT will.
  • status/playbackstate: a JSON-encoded object with the fields
    • "val" for the current playback state with 0=stopped, 1=playing, 2=paused
    • "kodi_playbackdetails": an object with further details about the playback state. This is effectivly the result of the JSON-RPC call Player.GetItem with the properties "speed", "currentsubtitle", "currentaudiostream", "repeat" and "subtitleenabled"
    • "kodi_playerid": the ID of the active player
    • "kodi_playertype": the type of the active player (e.g. "video")
  • status/progress: a JSON-encoded object with the fields
    • "val" is the percentage of progress in playing back the current item
    • "kodi_time": the playback position in the current item
    • "kodi_totaltime": the total length of the current item
  • status/title: a JSON-encoded object with the fields
    • "val": the title of the current playback item
    • "kodi_details": an object with further details about the current playback items. This is effectivly the result of a JSON-RPC call Player.GetItem with the properties "title", "streamdetails", "file", "thumbnail" and "fanart"

The addon listens to the following topics (prefixed with the configured topic prefix):

  • command/notify: Either a simple string, or a JSON encoded object with the fields "message" and "title". Shows a popup notification in Kodi
  • command/play: Either a simple string which is a filename or URL, or a JSON encoded object which correspondents to the Player.Open() JSON_RPC call
  • command/playbackstate: A simple string or numeric with the values:
    • "0" or "stop" to stop playback
    • "1" or "resume" or "play" to resume playback (when paused or stopped)
    • "2" or "pause" to stop playback (when playing)
    • "toggle" to toggle between play and pause
    • "next" to play the next track
    • "previous" to play the previous track
