How much does these savings contribute to their overall costs?
How much difference in that over dumb fridges?
How much difference in that over what can be replicated by a localized control system, at most sending reports through an "output only" line?
And what exactly would remote repair fix if some fridge hardware fails (that's not just switching to a failover hardware, that could just as well be decided by a local controller)? Since the answer is close to nothing, how much of the "remote repair" need isn't cyclical, addressing issues coming from complicating their fridges to the degree that remote repair is required?
