Smart Old Spice Deodorant Stand with Aqara Contact Sensor for Usage Tracking & Reminders

This Old Spice deodorant stand is designed to integrate an Aqara Door Window Contact Sensor to track when a deodorant stick is lifted and replaced. By integrating into your smart home system (I recommend Home Assistant) you can monitoring usage patterns, automate reminders, and trigger refill alerts.

Practical Applications:

🛒 Consumable Usage Tracking & Reordering

• Monitor how often deodorant is used and set up reminders to restock.

🔔 Daily Hygiene Routines & Reminders

• Trigger “Get Ready” routine when deodorant is used.
• Set up alerts if deodorant hasn’t been used by a certain time.

🫂 Caregiving & Assisted Living

• Helps parents or caregivers to monitor hygiene routines for children, elderly family members, or individuals with disabilities. 

🏠 Smart Home Integration & Automation

• Automate routines, log usage, or trigger any smart home actions you might find useful. 

How to Use the Stand:

Secure the Contact Sensor

• Use the double-stick foam tape that comes with the Aqara sensor to attach it inside the sensor slot at the bottom of the stand.
• Ensure the reset button is facing the reset hole in the stand for easy access.

Insert the Magnet into the Deodorant Stick

• Slide the magnet portion of the sensor into the included adapter piece.
• Press the adapter into the bottom twist mechanism of the deodorant stick—it should fit snugly with a pressure fit.

Ensure Proper Alignment

• When placing the deodorant in the stand, make sure the magnet aligns with the contact sensor.
• If the magnet is perpendicular to the sensor, it may not register as "closed" when the stick is in the stand.
