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.

Installable packages are available on the GitHub release page https://github.com/owagner/kodi2mqtt/releases/
The addon has three settings:
* the MQTT broker's IP address or host name (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/".
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"
- 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" and "file"
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" to resume playback (when paused)
- "2" or "pause" to stop playback (when playing)
- "next" to play the next track
- "previous" to play the previous track
