Tamper and schedule

Just bought a shelly motion sensor, and I have a few questions about the app.

Tamper, how does it send a notification to the phone? My sensor blink several colours but don't send any kind of notification.

And weekly schedule, does scenes schedule override it?

Last question, is it possible to the hardware kind of sleep before a scheduled detection?

Like only stays awake from 21h-08h without reading the lux, just time based. I'm using it on a busy zone during day and only want detection during night.
