Try This: A Mailbox That Tells You When the Mail is Here

“I put a SmartThings Multipurpose Sensor on my mailbox that tells me when the mail arrives.”

“Did the mail come?” “Uh, maybe? I’ll go check. Nope.” This solution has worked as long as the postal service has existed, but we think there’s a smarter way. Use the SmartThings app and a Multipurpose Sensor to banish the guessing game for good.

  • Use the “Add Device” feature in the SmartThings app to pair a SmartThings Multipurpose Sensor with your SmartThings Hub.

  • Place the SmartThings Multipurpose Sensor on the inside door of your mailbox to act as an open/close sensor
  • Use the “Smart Home Monitor-Custom” SmartApp in the Marketplace section of the SmartThings app to configure your Multipurpose Sensor to alert you when the mailbox is opened.

  1. You can also put a motion sensor in the back of the mailbox. That’s what I did.

  2. My concern is that I have a brick mailbox with a metal mailbox inside it. Does one think the Multipurpose sensor would work inside my setup?
    I know it sounds nuts, but I have actually gone through the trouble of drilling through my mailbox and I have a wire that runs from the mailbox to my house. My original plan was to use a Raspberry Pi to notify me. That is before I got into z-wave and Smart Things. Given I have the wire running, could I connect a wired sensor (I was thinking a tilt switch) on one end and on the other end have a door switch with external inputs to notify me of the mailbox being opened?

    • Mine does not work INSIDE the box – too much metal, but it did work mounted on the outside. The only problem was that after a few months the sensor failed because they are not outdoor friendly. I loved the feature, but now I’m back to stalking the mailbox…

      • Tried this same thing, range not quite good enough to reach from inside the mailbox – would have had to drill thru a brick mailbox to get an antenna in there. For those with just a metal or plastic box, would be a lot simpler to accomplish!

  3. What really is needed are z-wave sensors that are outdoor friendly.

  4. I did something very similar, but needed a slightly different approach due to distance and not wanting to block the mailbox opening with a large sensor.
    I purchased an archetectural mailbox, and added an open close sensor that has an hookup for an external contact.
    I mounted a weatherproof plastic box on the back of the mailbox post, drilled a hole through the post and ran a wire into the mailbox. The reason I mounted on the back is to remove as much material (post, mailbox, etc) from between the sensor and the nearest other z-wave device to maintain a signal. It’s about 25 feet from the mailbox to the smart switch in the front room.
    Inside the mailbox I put a normal window/door alarm contact wired out to the sensor in the weatherproof box. it is mounted under the mail drop door and cannot be seen or tampered with unless you unlock the mailbox storage area.
    So far it’s been working very well.

  5. I started using the sensor velcro inside my mailbox, but was getting too many false alerts. Not sure if it was vibration from cars driving by or a faulty sensor.

  6. The samsung multisensors are zigbee so the range doesn’t reach my mailbox. If only it was z-wave plus.

  7. I was misled by this website and its salespeople that this apparatus would work for me after I had ordered it online. When it got down to the nuts and bolts of what I would actually have to do to make it work, they (more experienced employee than the original one that misled me) admitted it “probably” would not work since my mailbox is a whole fifty feet away from my house. You’d think they would mention this among all this hype of how easy it is to install this system and, ta-da!, you’re getting mailbox notifications by text. Here’s a quote from one of the disappointing emails they sent me:
    “…SmartThings is designed for home use and may not be the best option to monitor your mailbox.”

    I suggest potential buyers take this into consideration. I was able to cancel my order, so I was only out for the cheap plastic mailbox I bought.
