SmartThings Multipurpose Sensor to Detect Mailbox Opening

General
1

Hey everyone, I wanted to share my recent project where I upgraded my mailbox sensor setup using the SmartThings MultiPurpose Sensor (V5). I’ve been using a Wyze contact sensor before, but I wanted something more reliable and maintainable. Let me walk you through how I did it and the benefits I’ve seen so far!

The Problem with the Old Setup

My previous setup involved a Wyze contact sensor glued directly to the mailbox. While it worked, replacing the battery was a hassle because of the adhesive. I knew there had to be a better way to make it more serviceable without sacrificing functionality.

The Solution: Peanut Plug and Tic-Tac Container

I decided to use a Peanut Plug and the SmartThings MultiPurpose Sensor for this project. The key to making it work was repurposing an empty Tic-Tac container. Here’s how I did it:

  1. Materials Needed

    • SmartThings MultiPurpose Sensor (V5)
    • Peanut Plug
    • Empty Tic-Tac container
    • Drill and Dremel tool
    • Screws

  2. Modifying the Tic-Tac Container

    • I drilled holes in the container to fit the sensor’s magnet part snugly. This ensured a secure fit without any adhesives.
    • I then cut the container in half to create a holder for the sensor body, making it easy to access the battery compartment.

  3. Mounting the Sensor

    • Using screws, I mounted the modified Tic-Tac container to the inside of the mailbox. The screws were short enough to avoid penetrating the outer wall, keeping the mailbox’s aesthetics intact.

  4. Testing the Setup

    • After installing the sensor, I tested it by opening and closing the mailbox. The sensor immediately detected the motion and sent notifications to my phone.

Why This Setup Works

  • Ease of Battery Replacement: The Tic-Tac container design makes it incredibly easy to slide out the sensor for battery changes without any tools.
  • Durability: The sensor is securely mounted without any adhesives, reducing the risk of it falling off or getting damaged.
  • Aesthetic Appeal: The setup blends seamlessly into the mailbox, maintaining its original look.

Tips for Others

If you’re considering a similar project, here are a few tips:

  • Choose the Right Container: Look for a container that fits your sensor snugly and can be easily modified.
  • Use Short Screws: This ensures you don’t compromise the mailbox’s structural integrity.
  • Test Thoroughly: Before finalizing, test the sensor in different lighting and weather conditions to ensure reliability.

Final Thoughts

Upgrading my mailbox sensor was a fun DIY project that paid off in the end. It’s now more reliable, easier to maintain, and blends in perfectly with my mailbox. If you’re looking to enhance your mailbox notifications without the hassle of frequent replacements, I highly recommend this setup!
