edifier_es300

Control an Edifier ES300 speaker over Wi-Fi, without the Edifier Home app. Ships an asyncio library and a click-based command-line interface.

• Library (edifier_es300): stdlib-only, fully async.
• CLI (python -m edifier_es300): thin wrapper over the library; needs click.

Requirements

• Python 3.13+
• click (CLI only — the library has no third-party dependencies)

uv sync        # or: pip install click

Library usage

Everything is async. The ES300 connection is an async context manager — reuse a single connection for a burst of commands (the device drops an idle socket after a few seconds).

import asyncio
from edifier_es300 import ES300, Source, EqPreset, LightEffect, LightColor


async def main():
  async with ES300("192.168.1.123", 8080) as device:
    print(await device.status())  # parsed Status (see below)

    await device.volume(20)  # 0..30
    await device.play()  # resume
    await device.pause()  # pause
    await device.play_pause_toggle()  # toggle
    await device.next_track()
    await device.previous_track()

    await device.input_source(Source.AIRPLAY)

    await device.light_switch(True)
    await device.brightness(60)  # 0..100
    await device.light_effect(LightEffect.BREATHING)
    await device.light_color(LightColor.YELLOW)

    await device.eq_preset(EqPreset.VOCAL)
    await device.eq_custom((10, 5, 0, 0, 0, -5))  # 6 gains, tenths of a dB (-30..30)

    await device.timer_shutdown(30)  # sleep timer in minutes (0 = off)
    await device.shutdown()  # power off (no remote power-on; physical button to wake)


asyncio.run(main())

Internally the context manager holds the socket open and runs a background task that reads every inbound frame. Each command carries a generated id; the device echoes it in its reply, and the background task hands the reply to the awaiting call — so await device.volume(20) returns only once that command's ack comes back.

Discovery

ES300.discover() broadcasts on the LAN and returns a list of ready-to-use ES300 objects (host, port, and name filled in):

speakers = await ES300.discover(seconds=3.0)
for speaker in speakers:
    print(speaker)            # "EDIFIER ES300  192.168.1.123:8080"

async with speakers[0] as device:
    await device.volume(15)

Return values & errors

• Command methods (volume, play, input_source, eq_custom, …) return the device's raw ack frame (a FrameData dict). They raise CommandFailed if the device acks with a non-success message, or EndOfStream if the socket drops before the ack arrives.
• status() returns a Status | None (None only if the device stays silent).

Live callbacks

Register callbacks to react to unsolicited frames the device pushes while a connection is held open. Both are usable as decorators and hold the callback by weak reference (drop your reference and it stops firing):

async with ES300("192.168.1.123") as device:
    @device.status_callback
    async def on_status(status: Status):
        print("state changed:", status.volume)

    @device.heartbeat_callback
    async def on_heartbeat(frame):
        print("heartbeat")

    await asyncio.sleep(60)  # callbacks fire as frames arrive

Status

str(status) renders a human-readable dump (this is what the CLI status prints):

playing: - / - (status <PlayerStatus.PLAYING: 1>)
volume : 6 / 30
source : <Source.USB: 2>
effect : <LightEffect.STATIC: 1>
color  : <LightColor.YELLOW: {'r': 255, 'g': 170, 'b': 60}>
eq     : <EqPreset.CLASSIC: 0> gains=[20, 10, 0, -5, 5, 10]
battery: 40% (<BatteryStatus.DISCONNECTED: 2>)
timer  : off

Fields: volume, max_volume, song, lyric, player_status, input_source, light_effect, sound_index, eq_selected_index, eq_gains, battery, and raw (the full status frame for anything not surfaced).

Enums

Source, EqPreset, and LightEffect are IntEnums, so methods also accept a plain int. Setting eq_custom gains automatically selects EqPreset.CUSTOMIZED.

CLI usage

python -m edifier_es300 [--host IP] [--port N] COMMAND [ARGS]

• --host — speaker IP. Omit it to auto-discover the first speaker on the LAN.
• --port — control-channel TCP port (default 8080).

Examples

python -m edifier_es300 discover
python -m edifier_es300 status                       # auto-discover, then dump state
python -m edifier_es300 --host 192.168.1.123 volume 22
python -m edifier_es300 source airplay
python -m edifier_es300 light-effect breathing
python -m edifier_es300 light-color yellow
python -m edifier_es300 eq-preset vocal
python -m edifier_es300 eq -- 10 5 0 0 0 -5          # use -- so negatives aren't read as options

Note: negative EQ gains look like CLI options, so prefix the gain list with --.
