alt Hacker News> It's not immediately obvious to me why fridges in supermarkets need remote control
I don’t know to what degree control is needed, but remote supervision of cold holding temperatures is good to make sure food doesn’t spoil. Most places that don’t have networked fridges have staff manually logging the cold holding temperatures to make sure things are working.
Again, though, I don’t know about making changes though.

I remember having to do this every few hours 25 years ago when working at a store part-time as a student.
Having networked telemetry seems like a good idea, just not sure why they would need remote control too - that seems far more dangerous than necessary.
In this case it's not like the devices were turned off, they were put on "defrost" which means heating up to 50°C (122°F). Why would you need the ability to remotely set all your fridges to defrost??
