Calling this interface can automatically generate cyclic random offline passwords and deliver them to the door lock device;Note: This interface only generates the password and does not save it. You need to additionally call the [Add Password] interface to synchronize and store this password information to the cloud server; otherwise, it cannot be queried or managed in the password list. Example: Set a weekend cycle from 8:00 AM to 5:00 PM. The parameters should be: effectiveTime = 08:00, failTime = 17:00, validWeekdays = 0,6. The system will start checking if the current day is a weekend from that day. If it is a weekend, the password will be effective, with a validity period from 8:00 AM to 5:00 PM; if it is not a weekend, the password will be invalid.Special instructions regarding pwAdmin and newPwAdmin: If the door lock is bound through [Door Lock Binding (Apartment)], then it is not pwAdmin or newPwAdmin obtained from the lock transmission end. Instead, it is the room password (roompassword) used at the time of binding.
