Transition conditions 306 can include a myriad of different conditions that may define how a state machine transitions from one state to another. Each state machine can have its own set of transition conditions, and examples of state machine specific transition conditions can be found in United States Publication No. 2015/0022367. The conditions can define thresholds that may be compared against any one or more of the following inputs: sensor data values, time clocks, and user interaction events (e.g., hush events). State change transitions can be governed by relatively simple conditions (e.g., single-criteria conditions), or relatively complex conditions (e.g., multi-criteria conditions). Single-criteria conditions may compare one input to one threshold. For example, a simple condition can be a comparison between a sensor data value and a threshold. If the sensor data value equals or exceeds the threshold, the state change transition may be executed. In contrast, a multi-criteria condition can be a comparison of one or more inputs to one or more thresholds. For example, a multi-criteria condition can be a comparison between a first sensor value and a first threshold and a comparison between a second sensor value and a second threshold. In some embodiments, both comparisons would need to be satisfied in order to effect a state change transition. In other embodiments, only one of the comparisons would need to be satisfied in order to effect a state change transition. As another example, a multi-criteria condition can be a comparison between a time clock and a time threshold and a comparison between a sensor value and a threshold.
