The temp in a freezer should never need adjustment. In fact, once the installer sets it, it should never be touched again. The only thing that should have anything like internet access is an alarm with a thermometer so you know when it's not working.
True before the invention of variable-speed compressors, predictive defrost, and grid spot pricing
There are a LOT of savings to be had in automation on newer hardware.
If it's systematic, the whole thing can stay on a local controller. The question is about Ilternet connection, no one asked to get rid of automation.
If it requires frequent changing due to factors outside of the store, I would also wonder what they're doing with these.
Grid spot pricing, Corporate hours management. Complaints from a store about the need to defrost a specific unit.
All the stores hit a "cloud" server the manufacturer manages, letting a single corporate location call the shots on consumption. I also find it likely they can call up individual VFD's and run diagnostics.
Yes, since the dawn of refrigeration, we've gotten along fine without it, but I wouldn't say it's useless to have bidirectional communication because some idiot installers in cooperation with the idiot supermarket IT let the controller have a public IP or because the vendor didn't think to lock remote manual defrost to a sane time limit.
Why not let the client manage the cloud server?
No money in letting the market chain self-host :)
Presumably, the manufacturer would do better at updates and monitoring. That said, looking at where we are, i'm not so sure.
LOL, good one.
ok, a marginally bad manufacturer who has the client paying through the nose for monitoring an updates would do a better job than a grocery store chain admin.
That bar is still apparently too high to reflect reality
