As noted by jeremywillans this no longer works in HA 2021.7+. In October of last year the core media_player service has been updated and has added some of the functionality (repeat, shuffle) that this plugin provided. This repository will be archived and it's no longer supported.

This component creates a service sonos_player_modes.set_mode that lets you change playback modes on any one of your Sonos speakers. Requires the sonos component to be already setup.

1. Copy the custom_components forlder in your HA configuration folder (or install with HACS).
2. Add

   sonos_player_modes: 

   to the configuration.yaml

• entity_id: entity id of the speaker (eg. media_player.bedroom)
• mode: playback mode. Supported modes: NORMAL, REPEAT_ALL, REPEAT_ONE, SHUFFLE, SHUFFLE_NOREPEAT, SHUFFLE_REPEAT_ONE
