It's businesses fridges that are getting hacked. So in theory it could do more than that, it should be able to automatically create a maintenance ticket, trigger a stock check for the part if it's out of stock create a purchase order for the part.

It could also flag if it has been not closed properly especially if there are out of hours stock fill and or for stockroom fridges.

It allows central control over power usage and better management there and local control based on weather forecast.

Allows better control over defrost cycles. Though this last one could arguably be better done by using on device machine learning.

Consumer level smart fridges though, yeah no point whatsoever.
