msmart-ng

A Python library for local control of Midea (and associated brands) smart air conditioners.

Code Quality Checks PyPI

If a devices uses one of the following apps it is likely supported:

  • Artic King (com.arcticking.ac)
  • Midea Air (com.midea.aircondition.obm)
  • NetHome Plus (com.midea.aircondition)
  • SmartHome/MSmartHome (com.midea.ai.overseas)
  • Toshiba AC NA (com.midea.toshiba)
  • 美的美居 (com.midea.ai.appliances)

Note: Only air conditioner devices (type 0xAC) are supported.

See usage to determine if a device is supported.

Features

Async Support

The device, LAN and cloud classes have all been rewritten to support async/await syntax.

from msmart.device import AirConditioner as AC

# Build device
device = AC(ip=DEVICE_IP, port=6444, device_id=int(DEVICE_ID))

# Get capabilities
await device.get_capabilities()

# Get current state
await device.refresh()

Device Discovery

A new discovery module can discover and return ready-to-use device objects from the network. A single device can be discovered by IP or hostname with the discover_single method.

Note: V3 devices are automatically authenticated via the Midea cloud.

from msmart.discover import Discover

# Discover all devices on the network
devices = await Discover.discover()

# Discover a single device by IP
device = await Discover.discover_single(DEVICE_IP)

Less Dependencies

Some external dependencies have been replaced with standard Python modules.

Code Quality

  • The majority of the code is now type annotated.
  • Code style and import sorting are enforced by autopep8 and isort via Github Actions.
  • Unit tests are implemented and executed by Github Actions.
  • A number of unused methods and modules have been removed from the code.
  • Naming conventions follow PEP8.

Installing

Use pip, remove the old msmart package if necessary, and install this fork msmart-ng.

pip uninstall msmart
pip install msmart-ng

Usage

CLI

A simple command line interface is provided to discover, query and contorl devices.

$ msmart-ng --help
usage: msmart-ng [-h] [-v] {discover,query,control,download} ...

Command line utility for msmart-ng.

options:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit

Command:
  {discover,query,control,download}

Each subcommand has additional help available. e.g. msmart-ng discover --help

Discover

Discover all devices on the LAN with the msmart-ng discover subcommand.

$ msmart-ng discover
INFO:msmart.cli:Discovering all devices on local network.
...
INFO:msmart.cli:Found 2 devices.
INFO:msmart.cli:Found device:
{'ip': '10.100.1.140', 'port': 6444, 'id': 15393162840672, 'online': True, 'supported': True, 'type': <DeviceType.AIR_CONDITIONER: 172>, 'name': 'net_ac_F7B4', 'sn': '000000P0000000Q1F0C9D153F7B40000', 'key': None, 'token': None}
INFO:msmart.cli:Found device:
{'ip': '10.100.1.239', 'port': 6444, 'id': 147334558165565, 'online': True, 'supported': True, 'type': <DeviceType.AIR_CONDITIONER: 172>, 'name': 'net_ac_63BA', 'sn': '000000P0000000Q1B88C29C963BA0000', 'key': '3a13f53f335042f9ae5fd266a6bd779459ed7ee7e09842f1a0e03c024890fc96', 'token': '56a72747cef14d55e17e69b46cd98deae80607e318a7b55cb86bb98974501034c657e39e4a4032e3c8cc9a3cab00fd3ec0bab4a816a57f68b8038977406b7431'}

Check the output to ensure the type is 0xAC and the supported property is True.

Save the device ID, IP address, and port. Version 3 devices will also require the token and key fields to control the device.

Note: V1 Device Owners

Users with V1 devices will see the following error:

ERROR:msmart.discover:V1 device not supported yet.

I don't have any V1 devices to test with so please create an issue with the output of msmart-ng discover --debug.

Query

Query device state and capabilities with the msmart-ng query subcommand.

Note: Version 3 devices need to specify either the --auto argument or the --token, --key and --id arguments to make a connection.

$ msmart-ng query <HOST>

Device capabilities can be queried with the --capabilities argument.

Control

Control device state with the msmart-ng control subcommand. The command takes a space seperated list of key-value pairs of settings to control.

Enumerated settings like operational_mode, fan_speed, and swing_mode can accept integer or string values. e.g. operational_mode=cool, fan_speed=100 or swing_mode=both.

Number settings like target_temperature can accept floating point or integer values. e.g. target_temperature=20.5.

Boolean settings like display_on and beep can accept integer or string values. e.g. display_on=True or beep=0.

Note: Version 3 devices need to specify either the --auto argument or the --token, --key and --id arguments to make a connection.

$ msmart-ng control <HOST> operational_mode=cool target_temperature=20.5 fan_speed=100 display_on=True beep=0

Home Assistant

Use this fork of midea-ac-py to control devices from Home Assistant.

Python

See the included example for controlling devices from a script.

Docker

A docker image is available on ghcr.io at ghcr.io/mill1000/msmart-ng. The container should be run with --network=host to allow broadcast packets to reach devices on the local network. Additional arguments to the container are passed to the msmart-ng CLI.

$ docker run --network=host ghcr.io/mill1000/msmart-ng:latest --help
usage: msmart-ng [-h] [-v] {discover,query} ...

Command line utility for msmart-ng.

options:
  -h, --help        show this help message and exit
  -v, --version     show program's version number and exit

Command:
  {discover,query}
