yoto-api 4.0.0

A python package that makes it a bit easier to work with the yoto play API. Not associated with Yoto in any way.

yoto_api

Async Python wrapper for the Yoto API: control players, browse the card library, react to live MQTT playback events.

Quick start

import asyncio
from yoto_api import YotoClient

async def main():
    async with YotoClient(client_id="your_client_id") as client:
        auth = await client.device_code_flow_start()
        print(auth["verification_uri_complete"])
        await client.device_code_flow_complete(auth)

        await client.refresh()
        for pid, player in client.players.items():
            print(pid, player.device.name, player.model)

        async def on_update(player):
            print(player.last_event.playback_status,
                  player.status.battery_level_percentage)

        await client.connect_events(list(client.players), on_update=on_update)
        await client.pause(next(iter(client.players)))
        await asyncio.sleep(60)
        await client.disconnect_events()

asyncio.run(main())

If you already have a refresh token:

async with YotoClient(client_id="your_client_id") as client:
    client.set_refresh_token(refresh_token)
    await client.refresh()

For consumers managing OAuth + session externally (e.g. HA core):

client = YotoClient(session=my_aiohttp_session)
client.token = Token(access_token=..., refresh_token=..., ...)
# caller owns the session — won't be closed by client.close()

Data model

YotoPlayer aggregates typed sub-objects (one per data source) plus a root-level is_online:

• player.device (Device): immutable identity from /devices/mine.
• player.info (PlayerInfo): settings, mac, firmware from /config.
• player.status (PlayerStatus): basic live telemetry from MQTT data/status (battery, volume, charging, day mode).
• player.extended_status (PlayerExtendedStatus): the richer telemetry from MQTT status/full or the REST /config shadow (network, disk, uptime, raw battery). A superset of PlayerStatus. Yoto doesn't document this one, so it can be incomplete or change without notice.
• player.last_event (PlaybackEvent): live playback state pushed via MQTT (track, position, volume).
• player.is_online (bool): connection state, from MQTT presence and REST.

All are always present (default-initialised). The *_refreshed_at, last_event_received_at and online_refreshed_at timestamps tell you whether data has actually been received. On top of that, status and extended_status carry updated_at: when that telemetry was current device-side. Gate on it if you care about freshness.

Common methods

All public methods are async.

Refresh over REST (update_*): a one-shot snapshot, returned and stored, works even when the device is offline.

await client.update_player_list()           # /devices/mine
await client.update_player_info(device_id)  # /config — info + info.config
await client.update_player_extended_status(device_id)  # /config shadow — extended_status (offline/cold-start fallback)
await client.update_library()               # /card/family/library — client.library
await client.update_groups()                # /card/family/library/groups — client.groups
await client.refresh()                      # list + all info

Refresh over MQTT (request_*): ask the device to push fresh data. It arrives on your on_update callback, so connect first with connect_events.

await client.request_player_status(device_id)           # -> player.status
await client.request_player_extended_status(device_id)  # -> player.extended_status

Groups are user-defined labels over library cards (a card can sit in several groups at once). Each Group in client.groups carries the card IDs in card_ids; cross-reference them against client.library for the card metadata.

MQTT:

await client.connect_events(player_ids, on_update=cb, on_disconnect=cb)
await client.subscribe_player_events(device_id)
await client.unsubscribe_player_events(device_id)
client.is_mqtt_connected
await client.reconnect_events()
await client.disconnect_events()

Callbacks may be sync or async.

Player commands (MQTT, ~50 ms):

await client.play_card(player_id, "card_id", chapter_key="01", track_key="01")
await client.pause(player_id)
await client.resume(player_id)
await client.stop(player_id)
await client.set_volume(player_id, 50)            # 0-100
await client.set_sleep_timer(player_id, 600)      # seconds
await client.set_ambients(player_id, 255, 0, 0)   # RGB
await client.next_track(player_id)
await client.previous_track(player_id)
await client.seek(player_id, position=30)

Settings (REST PUT):

import datetime
await client.set_player_config(
    player_id,
    day_time=datetime.time(7, 30),
    night_max_volume_limit=8,
    day_ambient_colour="#40bfd9",
    repeat_all=True,
    day_display_brightness_auto=True,  # or day_display_brightness=80
)
await client.set_alarms(player_id, alarms=[...])
await client.set_alarm_enabled(player_id, index=0, enabled=False)

JWT helpers (no API call):

from yoto_api import get_account_id, has_scope
account_id = get_account_id(client.token.access_token)
can_status = has_scope(client.token.access_token, "family:device-status:view")

Errors

All failures raise a subclass of YotoError:

from yoto_api import YotoError, AuthenticationError, YotoAPIError, YotoMQTTError

try:
    await client.refresh()
except AuthenticationError:        # token expired or invalid
    ...
except YotoAPIError as err:        # HTTP / parse error (err.status_code on 4xx/5xx)
    ...
except YotoMQTTError:              # MQTT broker / aiomqtt error
    ...
except YotoError:                  # catch-all
    ...

Migration from 3.x

See MIGRATION_4.md. Short version: player.status splits into player.status (basic, MQTT) + player.extended_status (rich, MQTT or REST shadow), is_online moves to player.is_online, update_player_status → update_player_extended_status / request_player_extended_status, and the REST /status endpoint is gone.

Migration from 2.x

See MIGRATION_3.md. Short version: YotoManager → YotoClient, flat fields on YotoPlayer → sub-objects, and every method is now async.

Development

pip install -r requirements.txt -r requirements_dev.txt
python -m pytest tests/                      # unit, no creds

End-to-end tests need a .env at the repo root:

YOTO_CLIENT_ID=your_client_id
YOTO_REFRESH_TOKEN=optional_refresh_token

Then:

python -m pytest tests/e2e -m e2e -s

The first run prompts for a verification URL and writes the new refresh token back to .env. -s keeps the prompt visible. E2E tests are read-only and opt-in (-m e2e).

Scripts:

python scripts/check_unmapped.py   # list API/MQTT keys we don't parse
python scripts/debug.py            # rich TUI: pick a device, watch live state
python scripts/probe_mqtt.py       # 30s MQTT capture → mqtt_probe.log

MQTT vs REST notes

• data/events is pushed in real time. Subscribe and react.
• data/status is never pushed spontaneously. The firmware responds to MQTT command/status/request within ~150ms. The REST POST /command/status is acked but doesn't trigger an MQTT push — use client.request_player_status (which routes through MQTT).
• data/status (v1) is a subset: powerSrc, wifiStrength, ssid, temp, upTime, utcTime, utcOffset, totalDisk arrive only via MQTT status/full or the REST /config shadow, both feeding player.extended_status. Prefer client.request_player_extended_status (MQTT) for live values. client.update_player_extended_status() reads the REST shadow as a fallback (cold start or offline) and won't overwrite fresher live data.
