AC-Nexus — AI Agent Smart AC Controller v5.2.0

Cross-platform AC control library for Broadlink RM series IR blasters and Xiaomi MIoT-compatible IR remote controllers. Zero GUI dependency — designed for AI agents to clone, install, and control air conditioners programmatically. Now includes IR learning — teach the system codes from any original remote, no brand limits.

📢 Rebrand Notice: Formerly BroadlinkAC, now AC-Nexus (空调中枢). All Xiaomi IR remote controllers compatible with MIoT protocol are supported — just scan with Mi Home app to add, then control via local network. No brand limitations.

⚠️ Safety & Persistence

This skill writes durable state to the user's machine. init() creates ~/.ac_controller/config.json (API keys, device config, schedule templates) and starts a background scheduler daemon thread. The scheduler survives agent task completion — scheduled on/off times, auto-adjust, and storm auto-shutdown will continue to run autonomously. Always confirm with the user before:

Modifying or creating schedule templates

Enabling auto-adjust or typhoon auto-shutdown

Changing device configuration (brand, temperature rules, location)

To fully disable automation: set schedule_enabled=False and auto_adjust=False for the device, then call _cfg.save_config(_cfg.config).

Quick Start (Agent)

git clone https://github.com/oywq00008-cell/AC-Nexus.git
cd AC-Nexus
pip install -r requirements-core.txt

from acnexus_core import init, send_ac, fetch_weather

# One-time setup — all config persisted
init(
    baidu_key="your_baidu_key",
    location={"lat": 22.54, "lon": 114.05, "name": "Shenzhen"},
    brand="Gree"
)

# Control AC — auto-routes between Broadlink IR and Xiaomi MIoT
send_ac("on", "cool", 26, "auto")     # Turn on, cool 26°C, auto fan
send_ac("off", "cool", 26, "auto")    # Turn off

# Weather — dual source (Baidu default, falls back to QWeather)
weather = fetch_weather()

# Storm threat
from acnexus_core import typhoon_threat_distance
dist, name = typhoon_threat_distance()
if dist < 100:
    send_ac("off", "cool", 26, "auto")  # Storm protection: auto-shutdown

Multi-Brand Architecture (v5.2)

AC-Nexus supports multiple device providers simultaneously. Devices are organized by brand type in the config:

"devices": {
    "broadlink": {
        "e870723f41ee": {"host": "192.168.8.214", "model": "RM4 mini", ...}
    },
    "xiaomi_cloud": {
        "2003509235": {"host": "192.168.8.119", "token": "97af...", "model": "qjiang.acpartner.ac02", ...}
    }
}

Each provider's devices are fully isolated — separate schedules, temperature rules, and auto-adjust settings. send_ac() automatically detects the device type and routes commands:

Broadlink devices → IR raw hex sent via UDP
Xiaomi devices → MIoT protocol via local network (set_properties)

API Reference

Setup

Function	Description
`init(baidu_key=None, api_key=None, qw_host=None, location=None, brand=None)`	Initialize config + start background scheduler. Writes to `~/.ac_controller/config.json`. Idempotent.

⚠️ Device naming is critical for Agent usability. Each device's name field in config should be a human-readable room/location name (e.g. "二楼卧室", "客厅"). The Agent matches user intent ("关掉二楼房间的空调") by searching device names. Open the desktop app → click the ✏️ rename button next to the device dropdown to set meaningful names. | acnexus_core.config.save_config(cfg) | Save config to disk (atomic write) | | acnexus_core.config.find_device(mac) | Find device by MAC across all providers → (provider, device_dict) |

AC Control (Broadlink IR + Xiaomi MIoT Local)

Function	Description
`send_ac(power, mode, temp, fan, source="手动", mac=None)`	Send command. Auto-routes: `broadlink` → IR hex, `xiaomi_cloud` → MIoT `set_properties`. `power`: `"on"`/`"off"`. `mode`: `"cool"`/`"heat"`/`"dry"`/`"fan"`/`"auto"`. `temp`: 16-30. `fan`: `"auto"`/`"1"`/`"2"`/`"3"`. Pass `mac=` to target a specific device.
`decide_ac(outdoor_temp, mac=None)`	Run temperature rules → returns `(target_temp, mode)`
`get_device()`	Get current Broadlink device (for IR learning)
`get_current_device()`	Get current device config dict from `devices[provider][mac]`

send_ac covers the minimum universal set across all brands. MIoT devices use standard siid=3 (AC service) / siid=4 (fan service) — no per-model mapping needed.

Adding Xiaomi MIoT Devices

Step 1 — Get session via QR login:

from acnexus_core.cloud_auth import login_qr
# In a terminal: prints ASCII QR code automatically
# In Jupyter/GUI: pass a callback to render the QR image
session = login_qr()
# Returns dict with auth tokens for listing devices

Step 2 — Add device to config:

import acnexus_core.config as _cfg
from acnexus_core.xiaomi_cloud import list_devices

# List devices on this mi account
devices = list_devices(session)

# Pick an IR remote controller and add it
for d in devices:
    if d["model"] in ("lumi.acpartner.mcn02", "qjiang.acpartner.ac02"):
        _cfg.add_or_update_device(d["did"], {
            "did": d["did"],
            "host": d["ip"],
            "mac": d["mac"],
            "model": d["model"],
            "name": d["name"],
            "token": d["token"],  # Critical for local network control!
            "brand": "格力",      # Default brand, user changes in Mi Home app
        })
        break

_cfg.save_config(_cfg.config)

Step 3 — Control via local network (no cloud after this):

send_ac("on", "cool", 25, "auto")  # Automatically uses MIoT local network

Reading Xiaomi Device State

Unlike Broadlink (one-way IR), MIoT devices support reading current state:

from miio import Device
d = Device("192.168.8.119", "97af6abc63a7f95da50dc8710005a42d")
r = d.send('get_properties', [
    {'siid': 3, 'piid': 1},  # Power (True/False)
    {'siid': 3, 'piid': 2},  # Mode (0=cool 1=heat 2=auto 3=fan 4=dry)
    {'siid': 3, 'piid': 4},  # Temperature (16-30)
    {'siid': 4, 'piid': 2},  # Fan speed (0=auto 1=low 2=med 3=high)
])
print(f"Power={r[0]} Mode={r[1]} Temp={r[2]} Fan={r[3]}")

MIoT Protocol Details

All MIoT-compatible IR remote controllers share the same service IDs:

siid=3, piid=1: Power (True/False)
siid=3, piid=2: Mode (0=cool 1=heat 2=auto 3=fan 4=dry)
siid=3, piid=4: Target temperature (16-30)
siid=4, piid=2: Fan speed (0=auto 1=low 2=med 3=high)

⚠️ Note: Use siid=4, piid=2 for fan, not siid=3, piid=3 — the latter is read-only and does not trigger IR transmission.

IR Learning (support any brand on Broadlink)

Function	Description
`learn_one(host)`	Enter learning mode, wait for IR signal → raw hex or `None` (45s timeout)
`get_raw_code(name, power, mode, temp, fan)`	Look up learned code for custom device
`load_custom_codes()`	Load all custom codes from `~/.ac_controller/custom_codes.json`
`save_custom_codes(data)`	Persist learned codes
`list_custom()`	List custom device names

IR learning only works with Broadlink devices. Xiaomi MIoT devices use the pre-built IR code library on the device itself.

Weather & Alerts (Dual Source: Baidu + QWeather)

Function	Description
`fetch_weather()`	Current weather — auto-routes via Baidu/QWeather
`fetch_weather_alerts()`	Local weather warnings

Storm Tracking (Dual Source: China NMC + US NHC)

Function	Description
`fetch_typhoons()`	Active storms from NMC or NHC
`fetch_typhoon_detail(typhoon_id)`	Detailed track + forecast
`typhoon_threat_distance()`	Agent-critical: nearest storm distance (km) + name. <100km = should shutdown. Never throws — returns `(99999, "")` on error
`typhoon.judge_and_shutdown(log_func)`	One-call: fetch typhoon data → if <100km, shut down ALL devices across ALL brands + pause scheduler. Returns alerts list

Logger

Function	Description
`write_log(category, msg)`	Append daily log (thread-safe)
`read_log(date_str)`	Read log by date
`get_log_dates()`	List dates with logs

Common Agent Tasks

"Control a specific device (multi-device setup)"

from acnexus_core import init, send_ac
import acnexus_core.config as _cfg
init()

# List all devices across all providers
for provider, devs in _cfg.config["devices"].items():
    for did, dev in devs.items():
        print(f"[{provider}] {dev['name']} = {did[:8]}")

# Control a specific device by MAC/DID
send_ac("on", "cool", 25, "auto", mac="e870723f41ee")

"Add a new Xiaomi device for the user"

from acnexus_core.cloud_auth import login_qr
from acnexus_core.xiaomi_cloud import list_devices
import acnexus_core.config as _cfg

# Step 1: Login (terminal prints ASCII QR, user scans with Mi Home)
session = login_qr()

# Step 2: List devices and add IR remote controllers
devices = list_devices(session)
ir_models = {"lumi.acpartner.mcn02", "qjiang.acpartner.ac02", "chuangmi.remote.v6"}
for d in devices:
    if d["model"] in ir_models:
        _cfg.add_or_update_device(d["did"], {
            "did": d["did"], "host": d["ip"], "mac": d["mac"],
            "model": d["model"], "name": d["name"], "token": d["token"],
            "brand": "格力",
        })
_cfg.save_config(_cfg.config)
print(f"Added {len(devices)} device(s)")

"Read current state of a Xiaomi AC"

import acnexus_core.config as _cfg
from miio import Device

# Get device info from config
dev = _cfg.config["devices"]["xiaomi_cloud"]["2003509235"]
d = Device(dev["host"], dev["token"])
r = d.send('get_properties', [
    {'siid': 3, 'piid': 1}, {'siid': 3, 'piid': 2},
    {'siid': 3, 'piid': 4}, {'siid': 4, 'piid': 2},
])
POWER = {True: "开", False: "关"}
MODE = {0: "制冷", 1: "制热", 2: "自动", 3: "送风", 4: "除湿"}
FAN = {0: "自动", 1: "低", 2: "中", 3: "高"}
print(f"{dev['name']}: {POWER[r[0]['value']]} {MODE[r[1]['value']]} {r[2]['value']}°C {FAN[r[3]['value']]}")

"Is there a storm nearby?" / "Shut down all ACs due to storm"

from acnexus_core import init, typhoon
init()
# ✅ One-liner: shutdown all devices on all brands if storm < 100km,
#    also pauses scheduler to prevent auto-adjust/timed-on from
#    re-opening the AC. Returns list of alert dicts.
alerts = typhoon.judge_and_shutdown(print)
if not alerts:
    print("No storm threat — all clear")

"Auto-adjust based on outdoor temperature"

from acnexus_core import init, fetch_weather, decide_ac, send_ac
init()
w = fetch_weather()
if w:
    target, mode = decide_ac(float(w["temp"]))
    send_ac("on", mode, target, "auto")

"Learn IR codes for a custom brand"

from acnexus_core.ir_learner import learn_one, save_learned_codes
hex_code = learn_one("192.168.8.214")  # Broadlink device IP
save_learned_codes("MyAC", "gree", {"关机": hex_code})
send_ac("off", "cool", 26, "auto")  # Routes to learned code automatically

Scheduling & Automation

⚠️ All schedule changes are persistent — they survive Python process exit and will be executed by the background scheduler daemon. Always confirm with the user before enabling or modifying schedules.

The scheduler runs all devices across all providers. Typhoon auto-shutdown (<100km) pauses the scheduler for all devices.

Read current schedule

import acnexus_core.config as _cfg
from acnexus_core import init
init()

# Navigate the nested structure: devices[provider][mac]
provider = _cfg.config.get("current_brand_type", "broadlink")
mac = _cfg.config.get("current_device_mac", "")
dev = _cfg.config["devices"][provider][mac]
print(dev.get("active_template"))
print(dev.get("schedule_enabled"))

Create a schedule template (multi-group)

templates = _cfg.config.setdefault("schedule_templates", {})
templates["工作日"] = {
    "groups": [{
        "days": [1, 2, 3, 4, 5],
        "slots": [{
            "on": "08:00", "on_enabled": True,
            "off": "18:00", "off_enabled": True
        }]
    }, {
        "days": [6, 7],
        "slots": [{
            "on": "12:00", "on_enabled": True,
            "off": "23:00", "off_enabled": True
        }]
    }]
}
dev["active_template"] = "工作日"
dev["schedule_enabled"] = True
_cfg.save_config(_cfg.config)

Enable/disable auto-adjust (per device)

dev["auto_adjust"] = True
_cfg.save_config(_cfg.config)
