Hue motion sensor. Notification when i get mail and packages. But not when i are picking it up

In the “Then…” section:
– add card → Flow → Disable a flow → Choose the relevant flow

But you have to activate the Flow again. You can do it in the same flow in the “Then…” section:
– add card → Flow → Activate a flow → Choose the relevant flow → Delay x minutes

In general there are several ways to optimize a mailbox.

I have a normal mailbox without a parcel box.
I have a door sensor on the insertion flap, as @Marcel_Ubels has already suggested, and a door/tilt sensor on the removal flap.
When a letter is dropped in and I am not home, I get a push message. But if I am home, I get an announcement through my Sonos.
When I get home and the mailbox hasn’t been emptied yet, I get a new push message to remember to get the mail.
And so on…
