The folks at Gate want you to know when the postman is coming. Their new product,available now on Kickstarter, is a smart mailbox sensor that tells you when someone is digging in your post box or dropping off letters.

The system, which mounts to both traditional “rural” mailboxes as well as in-door “flap” models, pings you when the mail is coming and can even estimate an ETA for your next delivery. While I can’t imagine wanting to know when my mail was coming with any degree of accuracy, there are plenty of people and places where the mail-person’s visit is an important part of their day.

Early adopters can grab it for $199 right now and it installs in a few minutes and charges via solar. It ships in December.
