I wrote a a centralised alarm clock and reminder integration for Home Assistant which plays alarms and reminders on media players, with HA Media Browser support for selecting media and companion cards:
It builds on HA-Alarms-and-Reminders (thank you!), with changes via vibe coding.
Overview
- Alarms and reminders repeat in a loop until stopped; stopping playback on the target player (“Hey Google, stop” or pressing the hardware button/satellite control) stops the alarm to imitate a traditional alarm clock feel (in addition to the ability to stop alarm and reminders via service calls, voice and companion cards).
- Playback sequence is configurable per-item: loop announce time → announce name → announce message → media playback; all announcements are optional
- HA Media Browser support for media selection; supports multiple sources: local media, Music Assistant, DLNA, SpotifyPlus, Plex, Jellyfin, Radio Browser
- Pair it with the Noise Generator for more traditional alarm playback.
- Tested media players include Google Cast devices, Home Assistant Voice preview, Music Assistant media players, Spotify media players, and SpotifyPlus players; others may behave differently, especially around looping and user stop detection.
- Entities (alarm/reminder and a switch) per item plus a dashboard sensor that exposes the entire schedule for automations.
- Services exist for creating, editing, rescheduling, snoozing, stopping, deleting, and stop-all actions, along with metadata helpers for the UI and HA Assist/LLM intents for voice/AI control.
- Repeat patterns cover one-off, daily, weekdays, weekends, or a custom list of days, and can be edited after creation.
- Override volume can be set for each item
- Snoozing is available per alarm/reminder via services, the companion cards or assist, and you can set a global default snooze duration in the options flow.
- Entities (lights, switches, script, etc.) can be turned on when an alarm or reminder fires; available entities are configured in the integration so only approved entities appear in the UI.
- Companion cards for alarms and reminders to display, add, edit, control and delete alarms and reminders including support for media browsing and searching and media sampling
Limitations
- The integration was only tested on Google cast devices and Home Assistant Voice PE. Amazon, Apple, Sonos, and other media players have not been verified; expect fragile looping or stop recognition if you try them.
- Some media players, especially untested ones, may mis-detect the transition to the next loop as a user stop (which means that the loop will only run once) or user stops may be missed (and the alarm/reminder will continue looping despite user stopping playback)
- Spotify and SpotifyPlus cannot run TTS, so are not supported on reminders
- Artwork and media icons in the HA Companion app appear only when the phone is on the local network.
- Limited testing overall, integration likely contains a lot of bugs
- LLM functions has been updated but not tested at all, expect problems
