I'm a mechanical engineer for a firm that does a bit of work in factories. A lot of industrial equipment these days has an option to connect to a Building Automation System via IP or some other proprietary network protocol. Maybe it could be a late tier upgrade to be able to add a network card to machines that gives you the ability to remotely track parameters like fuel level, efficiency, output, recipe, remaining capacity in storage container etc. Players could set up alarms for if a certain parameter went above or below a threshold. It would also give you the option to put a machine in standby mode or change the recipe on a constructor. These are all things that a Building Automation System would be capable of in real life.
