Music Assistant can start music on a speaker that is switched off through a configured power control, such as a Home Assistant smart plug. The player appears as powered off instead of unavailable; starting playback turns its power on and waits up to ninety seconds for it to reconnect.
This also covers announcements and playback requested through Home Assistant, voice assistants and Spotify Connect. A stop or power-off request during startup cancels the waiting playback.
A separate Power off when idle setting switches a stopped player off after a chosen number of minutes. It starts disabled, and each grouped speaker follows its own timer. This completes the cycle for speakers that would otherwise remain powered after a single announcement.
