<li><b> reduceLog [average[=day]] </b> <br>
|
||||||
|
Reduces historical records within the limits given by the "time.*"-attributes to one record
|
||||||
|
(the 1st) each hour per device & reading.
|
||||||
|
At least one of the "time.*"-attributes must be set (pls. see table below).
|
||||||
|
Each of missing time limit will be calculated by the module itself in this case.
|
||||||
|
<br><br>
|
||||||
|
|
||||||
|
With the optional argument 'average' not only the records will be reduced, but all numerical
|
||||||
|
values of an hour will be reduced to a single average.
|
||||||
|
With option 'average=day' all numerical values of a day are reduced to a single average
|
||||||
|
(implies 'average'). <br><br>
|
||||||
|
|
||||||
|
By setting attributes "device" and/or "reading" the records to be considered could be included
|
||||||
|
respectively excluded. Both containments delimit the selected data from database and may
|
||||||
|
reduce the system RAM load.
|
||||||
|
The reading "reduceLogState" contains the result of the last executed reducelog run. <br><br>
|
||||||
|
|
||||||
|
The relevant attributes for this function are: <br><br>
|
||||||
|
|
||||||
|
<ul>
|
||||||
|
<table>
|
||||||

|
<br>
|

|
|
||||||
|
For compatibility reasons the reducelog command can optionally be completed with supplements "EXCLUDE"
|
||||||
|
respectively "INCLUDE" to exclude and/or include device/reading combinations from reducelog: <br><br>
|
||||||
|
<ul>
|
||||||
|
"reduceLog [average[=day]] [EXCLUDE=device1:reading1,device2:reading2,...] [INCLUDE=device:reading]" <br><br>
|
||||||
|
</ul>
|
||||||
|
This declaration is evaluated as Regex and overwrites the attributes "device" and "reading",
|
||||||
|
which won't be considered in this case. <br><br>
|
||||||
|
|
||||||
|
<ul>
|

<b>Note:</b> <br>
|
||||||
|
Even though the function itself is non-blocking, you have to set the attached DbLog device into
|
||||||
|
the asynchronous mode (attr asyncMode = 1) to avoid a blocking situation of FHEM !. <br>
|
||||||
|
It is strongly recommended to check if the default INDEX 'Search_Idx' exists on the table
|
||||||
|
'history'! <br><br>
