They aren’t fridges, it’s a grocery store. You have obviously been in one, there are cases with a dozen doors that all open to the same cold case.

There is a ton of refrigerant piping, multiple condensing units, multiple evaporators, relays, and sensors connected to a controller that automates the refrigeration system. Not standalone refrigerators.

I shouldn’t need to list the benefits of remotely monitoring a system that can cause tens or hundreds of thousands of dollars if it fails.

Given the perfectly workable alternative of not having remote monitoring and simply having the store manager contact a repair tech on the exceedingly rare occasion that there is an issue, yeah I think actually you do need to justify the added complexity and expense of making this kind of mundane equipment internet accessible.

These systems only exist because those economics were decided decades ago. Issues are not exceptions in systems like this. They are huge, complex, and interface with the public.

The systems track all kinds of data and are decent at predicting failures before they get expensive.

		Marketing. The restaurant industry doesn't have less skin in the game than grocery retailers re avoiding spoilage and net connected walk-in coolers and freezers are not a thing.

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.
