Monitor Open API v2 Postman Quick Test Kit

Files:
- monitor-openapi-v2.postman_collection.json
- monitor-openapi-v2.postman_environment.json

How to use:
1. Import both JSON files into Postman.
2. Select the Monitor Open API v2 Environment.
3. Fill account, password_md5, and api_imei.
4. Run Auth / Get Access Token first. It saves access_token and user_id into the environment.
5. Run Read-only Quick Test / List Devices. Copy devices[].imei into api_imei.
6. Use device_key only as a customer-visible device number for display or your own UI mapping. Do not use device_key in Open API parameters named imei unless an endpoint explicitly documents support for it.
7. Run read-only requests first, including Get Device Statuses, Get Tire BLE Sensor Bindings, and Get BLE Temperature/Humidity Sensors when testing BLE sensor devices.
8. Use requests under "Write Examples - Use Carefully" only when you are ready to create/update/delete data or send a remote unlock command to a confirmed test device.

BLE sensor notes:
- Tire pressure current readings are returned in status.ble_tire_pressure_list and realtime bleTire messages.
- Tire pressure binding/name/position rows come from GET /v2/tire-ble-mac.
- BLE temperature/humidity current readings are returned as status.ble_temp_jsonarray_str in REST status responses. Parse it as JSON when present.
- BLE temperature/humidity names and threshold settings come from GET /v2/device-ble-temps.
- Use devices[].imei as the parent tracker identifier. Use mac for BLE tire sensors and ble_id for BLE temperature/humidity sensors.

Smart lock notes:
- Unlock Main Smart Lock sends openLock to /v2/device-lock-cards/action.
- Unlock Sub-lock sends openSubLock to /v2/device-lock-cards/action.
- sub_lock_ble_id comes from status.sub_lock_json_str or realtime subLockInfo.
- sub_lock_password_md5_16 is MD5(password).substring(8, 24), lower-case hex.
- Lock/close state is confirmed from status.lock_status, subLockInfo, alarm push, or GET /v2/alarm-points. This kit does not include an undocumented close-lock command.

General notes:
- password_md5 is the MD5 hash of the account password.
- api_imei is the API device identifier returned as devices[].imei by GET /v2/devices.
- Time range fields from_ms and to_ms use 13-digit Unix epoch milliseconds.
- Do not use Collection Runner for high-frequency polling or load testing.
