The 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.

I talked to a mn guardsman I know this morning about it. He said that the way they do the activations is in phases starting with MPs.
My understanding is that it’s basically a warning and a plan for where you’re at on the list of getting called up, so you know what to expect as the situation changes.
