Not at as complex as my car remote starting but I'm still pretty proud.
Since I recently switched over our last two doors to ring sensors I had two Samsung Multi Sensors on hand.
We have a timed virtual switch to remind kids to feed animals. It's always bugged me that it was something that had to be physically turned off. Not very "Elevated" . Often times the kids would do the chore and not turn off the reminder. This is my solution!
We have two large screw top bins in the kitchen. O ring seals and all.
I found a nice flat spot on the front and positioned the main portion of the sensor with masking tape. I positioned the magnet on various parts of the lid to test. Finally I came up with gutting the magnet out epoxying it inside the rim of the lid.
Then I was actually able to fine tune the position of the sensor in a way that if the magnet in the lid spins passed the sensor but is not all the way seated yet, it will still not register closed.
End result works fantastic! I used 3m tape for final mounting.
Now I can make rules to auto reset the reminder! I also joked with my wife that I could use the vibration sensor to notify when our Siamese goes passive aggressive at meal time....
