In an example implementation according to aspects of the present disclosure, a system, method, and storage medium comprising a plurality of sensors communicatively coupled to a microcontrol unit (MCU) wherein the MCU controls the transition between operational states. The MCU receives a system-related datum from one of the plurality of sensors. The MCU determines a control action based on the system-related datum. The MCU executes the control action on the system. The MCU sends a state change datum to a firmware wherein the state change datum indicates an operational change of the system based on the control action.
