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. Device-specific MIoT siid/piid auto-matched from miot-spec.org with 7-day local cache.
📢 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)
bash
git clone https://github.com/oywq00008-cell/AC-Nexus.git
cd AC-Nexus
pip install -r requirements-core.txt
python
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 — quick check + smart shutdown
from acnexus_core import typhoon_threat_distance, typhoon
dist, name = typhoon_threat_distance()
print(f"Nearest: {name} at {dist}km")
# Intelligent: wind-speed + distance tiered, TD excluded, pauses scheduler
alerts = typhoon.judge_and_shutdown(print)
Multi-Brand Architecture (v5.3.0)
AC-Nexus supports multiple device providers simultaneously. Devices are organized by brand type in the config:
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)
Initialize config + start background scheduler. Writes to ~/.ac_controller/config.json. Idempotent.
acnexus_core.xiaomi_local.fetch_miot_spec(model)
Fetch per-device siid/piid from miot-spec.org. 7-day local cache at ~/.ac_controller/miot_instances.json. Used automatically when adding devices — not needed by the Agent.
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)
⚠️ 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.
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. Xiaomi devices use per-model siid/piid from dev["miot_spec"] when available, falling back to hardcoded defaults (siid=3/4). No manual mapping needed.
Adding Xiaomi MIoT Devices
Step 1 — Get session via QR login:
python
from acnexus_core.xiaomi_cloud 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:
python
import acnexus_core.config as _cfg
from acnexus_core.xiaomi_cloud import list_devices
from acnexus_core.xiaomi_local import fetch_miot_spec
# 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"):
spec = fetch_miot_spec(d["model"]) # Auto-match siid/piid
_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
"miot_spec": spec, # Device-specific siid/piid (optional, safe fallback)
})
break
_cfg.save_config(_cfg.config)
Step 3 — Control via local network (no cloud after this):
python
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:
python
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
MIoT-compatible IR remote controllers use standard service IDs in most cases:
siid=3, piid=1: Power (True/False) — some devices use piid=5
siid=3, piid=4: Target temperature (16-30) — some use piid=3
siid=4, piid=2: Fan speed (0=auto 1=low 2=med 3=high)
⚠️ Per-device variation: Not all devices use the same piid values. fetch_miot_spec(model) auto-matches the correct values from miot-spec.org. The Agent should prefer reading dev["miot_spec"] from config — if present, use those values; if absent, fall back to the hardcoded defaults above.
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.

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 (intelligent wind-speed + distance tiered) pauses the scheduler for all devices.
Read current schedule
python
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"))
