mitsubishi-comfort 0.3.0

Async Python library for Mitsubishi minisplit control via Kumo Cloud and local API

mitsubishi-comfort

Async Python library for controlling Mitsubishi minisplit systems via the Kumo Cloud V3 API and local HTTP API.

Features

• Cloud discovery -- authenticate with Kumo Cloud to discover devices, retrieve credentials, and fetch device status
• Local control -- communicate directly with minisplit units over your LAN for low-latency operation
• Indoor units -- full control of mode, temperature setpoints, fan speed, and vane direction
• Kumo stations -- read outdoor temperature and signal strength from headless outdoor units
• Async native -- built on aiohttp for use in asyncio applications

Installation

pip install mitsubishi-comfort

Quick start

import asyncio
from mitsubishi_comfort import MitsubishiCloudAccount, IndoorUnit, Mode

async def main():
    # Discover devices via cloud API
    account = MitsubishiCloudAccount("[e-mail]", "password")
    await account.login()
    devices = await account.discover_devices()

    # Control a device locally
    info = list(devices.values())[0]
    unit = IndoorUnit(
        name=info.label,
        address=info.address,
        password_b64=info.password,
        crypto_serial_hex=info.crypto_serial,
        serial=info.serial,
    )
    await unit.update_status()
    print(f"Room temp: {unit.status.room_temperature}")

    await unit.set_mode(Mode.COOL)
    await unit.set_cool_setpoint(22.0)

asyncio.run(main())

API overview

Cloud account

MitsubishiCloudAccount(username, password) authenticates with the Kumo Cloud V3 API.

Method	Description
login()	Authenticate and obtain JWT tokens
refresh()	Refresh an expired access token
discover_devices()	Return dict[serial, DeviceInfo] with full credentials
get_sites()	List installation sites
get_zones(site_id)	List zones within a site

Indoor unit

IndoorUnit controls a minisplit indoor unit over the local HTTP API.

Method	Returns	Description
update_status()	bool	Poll device for current state
set_mode(Mode)	CommandResult	Set operating mode
set_cool_setpoint(temp)	CommandResult	Set cooling target temperature
set_heat_setpoint(temp)	CommandResult	Set heating target temperature
set_fan_speed(FanSpeed)	CommandResult	Set fan speed
set_vane_direction(VaneDirection)	CommandResult	Set vane direction

Kumo station

KumoStation reads data from headless outdoor units (no control commands).

Method	Returns	Description
update_status()	bool	Poll device for current state

Enums

• Mode -- OFF, COOL, HEAT, DRY, FAN, AUTO
• FanSpeed -- SUPER_QUIET, QUIET, LOW, POWERFUL, SUPER_POWERFUL, AUTO
• VaneDirection -- HORIZONTAL, MID_HORIZONTAL, MIDPOINT, MID_VERTICAL, VERTICAL, AUTO, SWING

Network discovery

probe_candidate_ips(devices, candidate_ips) matches device serials to LAN IP addresses by probing with device credentials.
