Mijia Control

Control Xiaomi Mi Home (米家) smart devices via Xiaomi Cloud API. Use when: user wants to control smart home devices (lights, AC, heater, bath heater, switches, etc.), check device status, or create automation scenes. Triggers: "开灯", "关灯", "开空调", "关空调", "开浴霸", "我要洗澡", "设备状态", "创建场景", "自动化", "米家", "smart home", "turn on/off", any home device control request. NOT for: non-Xiaomi devices, HomeKit-only devices.

Mi Home (米家) Control

Control Xiaomi smart home devices and create automations via cloud API.

Setup

Prerequisites: pip3 install micloud

Credentials: ~/.mijia_creds.json (chmod 600)

json

{"userId":"...", "serviceToken":"...", "ssecurity":"...", "cUserId":"..."}

If login requires 2FA (device trust verification), obtain credentials via browser:

1. Open https://account.xiaomi.com/pass/serviceLogin?sid=xiaomiio&_json=true in browser with existing cookies
2. POST to serviceLoginAuth2 with hash password to get ssecurity + location
3. Follow location URL to get serviceToken from cookies

Device Control

List devices

bash

python3 scripts/mijia.py devices

Read property

bash

python3 scripts/mijia.py get <did> <siid> <piid>

Set property

bash

python3 scripts/mijia.py set <did> <siid> <piid> <value>
# value: true/false for bool, integer for uint8, etc.

Note: Mesh devices (BLE switches) return code:1 on set — this is normal (async confirmation). The command still executes. Verify by reading the property after a 1-2 second delay.

Batch control

Create a JSON file with commands:

json

[
  {"did": "946635824", "siid": 2, "piid": 1, "value": true},
  {"did": "946633803", "siid": 2, "piid": 1, "value": false}
]

bash

python3 scripts/mijia.py batch /tmp/commands.json

MIoT Spec Reference

Each device has services (siid) → properties (piid). Look up specs at: https://home.miot-spec.com/spec/<model>

Common patterns:

• Switch/Light: siid:2 piid:1 = on/off (bool)
• 3-way switch: siid:2/3/4 piid:1 = channel 1/2/3 (bool)
• AC: siid:2 piid:1 = on/off, piid:2 = mode, piid:3 = target temp
• Bath heater: siid:2 = light, siid:3 = PTC heater, siid:10 = environment (temp sensor)
• Water heater: siid:2 piid:1 = on/off, piid:2 = target temp, piid:3 = current temp

Create Automation Scenes

bash

python3 scripts/mijia.py scene_create scene.json

Scene JSON format (see references/scene_template.json):

json

{
  "name": "回家自动开灯",
  "identify": "homelight_1234",
  "st_id": 8,
  "setting": {"enable": 1, "enable_push": 0},
  "trigger": {
    "key": "event.<did>.<siid>.<eiid>",
    "did": "<trigger_device_did>",
    "model": "<model>",
    "extra": "{\"siid\":2,\"eiid\":1}"
  },
  "action_list": [
    {
      "did": "<target_device_did>",
      "model": "<model>",
      "extra": "{\"props\":[{\"siid\":2,\"piid\":1,\"value\":true}]}",
      "type": "device_ctrl"
    }
  ]
}

Key fields:

• trigger.key: format event.<did>.<siid>.<eiid> for device events
• launch.attr_filter: optional conditions (e.g., only if light is off)
• action_list[].extra: JSON string with props array
• st_id: 8 = user automation
• home_id and uid are auto-filled if omitted

Predefined Scenes

🚿 Bath Mode (洗澡模式)

When user says "我要洗澡":

1. Read bathroom temp: get 927361805 10 1
2. If temp < 28°C → turn on bath heater: set 927361805 3 1 1 (暖风), target 30°C
3. If temp ≥ 28°C → skip heater
4. Turn on water heater: set 965879649 2 1 1, set 43°C: set 965879649 2 2 43
5. Turn on bathroom light: set 946635824 2 1 true

🐟 Auto Fish Feeding (出门自动喂鱼)

Feeds fish once per day when BOSS leaves home.

Architecture:

1. OpenClaw cron (every 5min): polls door lock event log via /user/get_user_device_data
2. If today has an auto-lock event (action=1) AND not fed yet → feed fish → record state
3. After feeding, all subsequent checks skip immediately (daily dedup)
4. State file ~/.fish_feed_state.json: tracks last feed date

Components:

• Door lock events: 智能门锁2 Pro (did: 1175215651), event key 2.1020, action=1 = auto-lock (leaving home)
• Fish feeder: 智能鱼缸 (did: 2026943875), action siid:2 aiid:1, in:[1] (1 portion)
  • ⚠️ Action 参数格式: "in": [1] 而不是 [{"piid":5,"value":1}]
• Script: scripts/fish_auto_feed.py

Manual commands:

bash

python3 scripts/fish_auto_feed.py              # Normal run
python3 scripts/fish_auto_feed.py --dry-run    # Check without feeding
python3 scripts/fish_auto_feed.py --force      # Feed regardless
python3 scripts/fish_auto_feed.py --status     # Show state

Trigger logic:

• Polls lock event log for auto-lock (action=1) today → feed fish
• Once fed, skips all further checks until next day
• No米家自动化 needed, pure OpenClaw polling

小爱音箱 TTS

Make the XiaoAI speaker say something aloud.

bash

python3 scripts/mijia.py tts <did> "<text>"
# Example: python3 scripts/mijia.py tts 100783118 "你好"

Flow: unmute → play-text → wait → pause playback → re-mute. This prevents the speaker from auto-playing music after TTS.

Important:

• Speaker may be muted (default state at night) — script handles unmute/re-mute automatically
• After TTS, always pause playback to prevent auto-music
• Cloud API cannot control screen UI — returning to clock display requires physical tap or voice command

Token Refresh

Tokens expire periodically. If API returns decode errors or auth failures:

1. Re-login via browser (same flow as initial setup)
2. Update ~/.mijia_creds.json with new serviceToken and ssecurity

The ssecurity changes each login. The serviceToken is session-bound.
