Unlike one-time-passcodes that only work a single time, periodic PINs are codes that are configured to work multiple times within a span of time. You’ll be able to set a start date and time, and an end date and time. The PIN will only work during this time period, and expire automatically after.
Periodic PINs can be created and configured without a hub with a local Bluetooth connection.
Want to create periodic PINs remotely? You’ll need an Aqara hub for that (see above!)
