You don’t need an Internet connection to have a control system keep temperature around a setpoint, though. That’s usually handled by a lower level circuit that will continue to operate in the case that the high level interface is not responding.
Observability is nice, but you don’t need to expose controls to do this, you could just have a Prometheus endpoint.
I suspect it’s because the manufacturer is trying to sell RaaS (refrigeration as a service) and to ensure they get their monthly dues, they “offer remote maintenance and monitoring” or something.
I suspect your suspicion is accurate. Scanning with BLE or a flipper shows the coolers at my local grocery also. It’s like the cars, they won’t secure it until someone makes it and even then they’ll secure it against their customers freedom, not hackers.
