alt Hacker NewsThey 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.
