| Implement to provide warning class sensor thresholds. Objects implementing |
| Sensor.Threshold.Warning must be instantiated in the correct hierarchy |
| within the sensors namespace. The following sensor hierarchies are |
| recognized: |
| airflow |
| altitude |
| current |
| energy |
| fan_tach |
| humidity |
| power |
| pressure |
| temperature |
| utilization |
| voltage |
| |
| Additionally, any object implementing Sensor.Threshold.Warning must also |
| implement Sensor.Value. |
| |
| properties: |
| - name: WarningHigh |
| type: double |
| default: NaN |
| description: > |
| The upper bound of the warning threshold. A value of 'NaN' is used to |
| indicate there is no threshold of this type. |
| - name: WarningLow |
| type: double |
| default: NaN |
| description: > |
| The lower bound of the warning threshold. A value of 'NaN' is used to |
| indicate there is no threshold of this type. |
| - name: WarningAlarmHigh |
| type: boolean |
| description: > |
| True if the sensor value has exceeded the defined bound. False if the |
| sensor value has not exceeded the defined bound. |
| |
| WarningAlarmHigh may be set to False to clear an alarm condition. The |
| behavior of setting WarningAlarmHigh to True is undefined. |
| - name: WarningAlarmLow |
| type: boolean |
| description: > |
| True if the sensor value has exceeded the defined bound. False if the |
| sensor value has not exceeded the defined bound. |
| |
| WarningAlarmLow may be set to False to clear an alarm condition. The |
| behavior of setting WarningAlarmLow to True is undefined. |
