If you put a Smart presents in your mail box how does it work?
I’m not sure I am following the thread title connection to the body…
But, you wouldn’t want to put a presence sensor in your mailbox. All that would do is tell you that your mailbox is present. That’s fine if you have a tendency to have your mailbox stolen, but, it won’t tell you when you get mail.
You’d want to use an open/close sensor like you’d put on a door or window.

I’ll attempt to answer the question in the title rather than the body of your post as the two don’t seem to go together?
The Fibaro Roller Shutter module can run a motor in forward and reverse, it can also auto detect stop limits etc.
