| Implement to provide hard shutdown class sensor thresholds. Objects |
| implementing Sensor.Threshold.HardShutdown 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.HardShutdown must |
| also implement Sensor.Value. |
| |
| properties: |
| - name: HardShutdownHigh |
| type: double |
| default: NaN |
| description: > |
| The upper bound of the shutdown threshold. A value of 'NaN' is used |
| to indicate there is no threshold of this type. |
| - name: HardShutdownLow |
| type: double |
| default: NaN |
| description: > |
| The lower bound of the shutdown threshold. A value of 'NaN' is used |
| to indicate there is no threshold of this type. |
| - name: HardShutdownAlarmHigh |
| type: boolean |
| description: > |
| True if the sensor value has exceeded the defined bound. False if the |
| sensor value has not exceeded the defined bound. |
| |
| HardShutdownAlarmHigh may be set to False to clear an alarm condition. |
| The behavior of setting HardShutdownAlarmHigh to True is undefined. |
| - name: HardShutdownAlarmLow |
| type: boolean |
| description: > |
| True if the sensor value has exceeded the defined bound. False if the |
| sensor value has not exceeded the defined bound. |
| |
| HardShutdownAlarmLow may be set to False to clear an alarm condition. |
| The behavior of setting HardShutdownAlarmLow to True is undefined. |
