Based on the application, some manufacturer do create custom controllers that monitor/capture environmental data in order to safeguard the equipment from experiencing catastrophic failure or performing triggered/scheduled reboots, brightness adjustments, etc based on specific events like local temp, fan speed, on-time hours, etc.
These were NEC MultiSync panels and yep, had a fairly rich set of op codes (page 26) -
