From my experience in a restaurant, those large commercial rooftop refrigeration/freezer units need attention several times a year. It's rare that your home fridge would have trouble that often but commercial units are more complicated and in a harsher environment. And supermarket installations are probably even more complicated.
Routine service and maintenance doesn't require net connectivity to schedule.
Not all issues are routine.
So we schedule service, and then we throw away all the food anyway because the problem cannot be addressed remotely.
Agreed. I was just addressing that it's not exceedingly rare to need to get a tech out on site to address something. Should the manager be on top of this, checking temps on all the cases every day? Absolutely, but I can see the argument for a more automated system of monitors/alarms that can get a tech dispatched before the manager has even noticed the problem.
