Add median* condition
The median condition determines the median value from a configured group
of properties and checks that against a defined condition to determine
whether or not the callback is called.
*Note: When 2 properties are used with the median condition, the
property determined to be the max is used instead of the average of the
2 properties. This is for providing a "worst case" median value.
An example would be to create a group consisting of multiple ambient
sensors where the median value from these ambient sensors would be used
to shutdown the system if above a given temperature.
i.e.)
- name: median temps
description: >
'If this condition passes the median ambient temperature
is too high(>= 45C). Shut the system down.'
class: condition
condition: median
paths: ambient sensors
properties: ambient temp
callback: ambient log and shutdown
op: '>='
bound: 45000
oneshot: true
Tested:
A defined median condition is generated according to the
MedianCondition class
The MedianCondition class produces a single median value from a
group of property values
Median value used against the given operation to determine if
callback is called or not
