I used over the counter mousetraps with Sonoff zigbee door / window sensor (SNZB-04) to make a smart mousetrap. I use the sensor to trigger an automation to send a notification and the initiate a light automation. This is not the first mousetrap HA project, but it’s a very simple take on the whole smart mousetrap.
PARTS LIST:
- d-Con Ultra Set Covered Snap Trap.
- Sonoff Zigbee door / window sensor (SNZB-04)
- 8×3mm Neodymium magnets
- Glue Gun
- 3D Printer (optional)
Instructions:
-
Apply two 8 x 3mm magnets onto the pull lever
-
Apply hot glue to magnets to set in place. I only wrapped the glue around the magnets in one direction to avoid interfering with the cover.
-
Add sensor to your HA instance. I set up the sensor first so that I could verify alignment when applying the sensor to the cover.
-
Set the mousetrap.
-
Apply door sensor with double sticky tape, ensuring the sensor reads closed before you set it into final position. The Neodymium magnets give you a larger window for alignment over the really weak magnet from Sonoff. My second revision uses a 3D printed mount for better adhesion.

Rev 1:
- Finally, complete whatever HA setup magic you want / need.
