If you have a sensor that you want to ignore during certain times for a given day, you can use a basic ignore model. This is best when the time frame is fixed and known ahead of time.
To do this, you can open the sensor Properties and go to the Ignore tab.
For each day of the week you want to ignore, you can select a start time and a period in minutes. For example, to do every weekday from 10:00 PM to 2:00 AM and from 9:00 PM to 2:00 AM on weekends, you can specify
If you want all of the sensors under a given policy or folder, you can set the ignore at that level and then in the individual sensors, select Use parent settings. The actual days and times will be greyed out and no longer apply.
