Hi @rljkoster!! Welcome to the Community! 
This is a known limitation with many presence sensors: they only ever send one event, telling you when they have detected someone. But they don’t send you an event to tell you “nothing is happening now over here!”.
With Apilio, you can add a timeout to your PIR condition to make sure that you are using data that is recent. This is like adding a way to make the sensor “false”, even if the sensor is not capable of sending this information How to setup time constraints for Conditions: delays and timeouts
Here’s an example where we use a PIR sensor with a timeout to only turn on a light for a while after someone has been detected:
Let me know if this is similar to your Logicblock! Thanks!
