Firstly create a Group address that will be used to disable the sensor ie PIRDISABLE
Open the sensor and under the occupancy tab select that PIRDISABLE Group and set to 'Disables'
Create a new Schedule on a device that supports Schedules and use the same PIRDISABLE's Group,
When the Schedule runs and that Group Address is set ON the PIR/Sensor will disable until that Group is subsiquently turned OFF again to reenable.
