Hello, I have an SNZB-06P Presence Sensor in my kitchen. I want BasicR4 to open with a scene when it detects someone.

I can do this on Ewelink. No problem.

So how can I make this scenario only work between 6:00 PM and 12:00 AM?

when setting a scene, select the effective period option at the bottom and there select when and how long the scene will be active
