AnarchoSnowPlow@midwest.social 18 hours agoThe door monitor mostly helps when a kid walks off leaving it open thinking they closed it.
The freezer temperature monitoring has saved the contents several times. A breaker had tripped once and I didn’t notice, it let me know that I needed a generator during a power outage, and one of the kids snuck an ice cream and left the lid wide open.
So yeah, it’s been useful. It’s not needed 99% of the time.

An alarm that beeps when the door is left open more than X minutes (say, 2 minutes) only requires a stupidly simple circuit and about $5 in parts.
No smarts needed (though it’s probably cheaper to make it with a microcontroller than have the timer circuit be done with discrete parts).
