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.

Nothing needs to be, but I do like to monitor door status and temperature for my fridge and deep freezers with home assistant.

They’re pissy cause it being open source and more efficient means that it’s gonna be more cost effective for people to use. Which is real bad if your company overcommitted to the slop and needs to recover losses.
