Get Mijia Device Token

Both LAN miIO and BLE devices need a token from Xiaomi Cloud (BLE also needs ble.key). Recommended open-source tool:

Xiaomi Cloud Tokens Extractor

Sign in with your Xiaomi Cloud account (email / Xiaomi ID + password, or QR scan), pick the server region (cn for mainland China, or leave empty to scan all regions), then list all devices under the account.

Tool output example

NAME:     Xiaomi Wireless Switch (Bluetooth)
ID:       blt.3.1fe2te3rokg00
BLE KEY:  8ac1c06d5989a8618c1158488a1b46b7
MAC:      18:C2:3C:28:45:44
IP:       112.232.158.153
TOKEN:    9d2d1a7c337fb00ddcb1f60c
MODEL:    lumi.remote.mcn001

Field mapping

Extractor	config.json devices[]	Notes
NAME	name / name_zh	Rename to your preferred English / Chinese label
ID	id	Copy as-is; BLE is often blt.3.…
TOKEN	token	Required
MODEL	model	Required; firmware classifies control by this
MAC	mac	Recommended; required for BLE
BLE KEY	ble.key	BLE devices only
IP	ip	Wi-Fi devices: LAN IP; pure BLE can leave empty

Optional: hotkey (a–z / 0–9, q reserved) for quick jump in Mijia.

Convert to firmware format

You can have an AI do this step — it is straightforward.

BLE device (has BLE KEY)

From the example above:

{
  "name": "Switch",
  "name_zh": "蓝牙无线开关",
  "ip": "",
  "token": "9d2d1a7c337fb00ddcb1f60c",
  "model": "lumi.remote.mcn001",
  "id": "blt.3.1fe2te3rokg00",
  "mac": "18:C2:3C:28:45:44",
  "ble": {
    "key": "8ac1c06d5989a8618c1158488a1b46b7"
  }
}

Notes:

• BLE KEY → ble.key (nested object, not a top-level string)
• Extractor IP is often a public / cloud address, useless for local BLE scan — leave ip empty
• Keep MAC as AA:BB:CC:DD:EE:FF

Wi-Fi device (no BLE KEY)

{
  "name": "DeskLamp",
  "name_zh": "台灯",
  "ip": "192.168.31.85",
  "token": "28398e0747a0adb0dca2b5c028c039c3",
  "model": "yeelink.light.lamp2",
  "id": "434412341",
  "mac": "B4:60:ED:03:2E:8A",
  "hotkey": "l"
}

Notes:

• Do not copy the Extractor's public IP; use the LAN address from your router (same subnet as Cardputer)
• Without BLE KEY, omit the ble field

Write to config

Put the object in the devices array of config.json, or add / edit via the Config Web page. After save, reboot or re-enter Mijia.

FAQ

• Login failed: Use a Mijia / Xiaomi Cloud account, not Roborock or other third-party apps; try QR login; watch region rate limits (~3–5 2FA attempts)
• Lists but control fails: Check token / model typos; for Wi-Fi verify LAN ip; for BLE verify mac and ble.key
• How to run: On Windows, use token_extractor.exe from the release; other platforms see the repo README
