People on life support: "back in my day you just pissed off a guy and they cut you for free, now you need to pay for the privilege, this country is going to shit."

"This is the TempCom 2300. It monitors and controls your refrigeration units, and allows you to log in and make changes. It's protected with a firewall to reduce the risk of unauthorized access."

"Oh yeah? Well, this is Frank. He can read thermometers, too. You can text him for a status update. He won't set the thermostat above freezing regardless of what calls he gets, because he knows it's his job to keep it cold."

I totally agree!

Even easier for Frank, make it a normally open/closed relay that sends a trap to an M&C or sends email/sms when its outside set boundaries. (work in this area) Its used for simple systems like this.

I can't see a reason why (and I grew up in restaurants) that my old man would want to change the freezer settings remotely. Also our guy was named Al, he looked like an Al, he talked like an Al and he could fix ANYTHING.

Best HVAC tech I've ever met, and I work in data centers (yes I will get hate, mine are from the 90's not this new shit). We had a reefer down he would fix it before we went below FDA temps. Also great at catching issues WAY before they became an issue.

There are more, but as a summary, he has found basically everything from personal computers to busses, to caviar factories, to hydro electric powerplants to malls and more having their control system exposed to the internet.
