detection.door.keyPeriod (Recurring password)

detection.door.keyPeriod: Recurring password

detection.door.keyPeriod · device scope · permission Config

What it does

Manage recurring passwords. Each call runs once. Smart-lock models often use struct inputData/outputData (cmd, key_id, schedule/password fields, code, etc.); follow capability list and payloads. Models with no fields may send {}.

Request URL

POST https://openapi-[DataCenter].easy4ip.com/openapi/v2/device.service.invoke

Minimum permission

The administrator does not need an extra permission on a device they bound. A shared device needs the basic configuration permission. A bound sub-user does not. A sub-account needs Config. Do not send channelId on device-scope capabilities. Mixing device and channel properties in one request returns DV2008. A timeout does not mean the action failed.

Request parameters

NameTypeRequiredDescription
tokenStringyesAccess token for an administrator, sub-user, or sub-account
deviceIdStringyesDevice serial number
productIdStringnoOptional. If sent and it does not match the device model → DV2009
serviceIdStringyesdetection.door.keyPeriod
inputDataObjectyesSame shape as One-time password (cmd, key_id, etc.; model subset)

Response data fields

Output is in result.data.outputData. Often includes code (result code; varies by model).
