SolarNetwork Aggregate Query Tool
This is a small node utility that can export SolarNetwork data as CSV, aggregated by date. The tool will query SolarNetwork for data based on the provided arguments, and then combine all result rows that occur on the same date into a single aggregate sum result for that date.
For example, if a raw query were to return data like
created,nodeId,sourceId,wattHours
"2017-01-01 00:00:00.000Z",123,"A",1000.0
"2017-01-01 00:00:00.000Z",123,"B",555.0
this tool would combine those two rows because they have the same
created
value into a single row like this:
created,nodeId,wattHours
"2017-01-01 00:00:00.000Z",123,1555.0
Notice the wattHours
value is the aggregate sum of the two raw
records.
Usage
Usage: node sn-agg-query.js [OPTION] [query]
Combine query results by date, adding their values together.
Alternatively, can output the raw data without aggregation.
-r, --raw output raw, unaggregated results
-n, --node=ID the node ID
-p, --source=ID+ a source ID (can be provided more than once)
-s, --start=DATE the starting date, as yyyy-MM-dd HH:mm
-e, --end=DATE the ending date, as yyyy-MM-dd HH:mm
-a, --aggregation=AGG the aggregate level, e.g. Hour
-h, --help show this help
Note that multiple source
arguments may be provided, for example
node sn-agg-query.js --node=123 --source=A --source=B ...
Development
This tool was created as a demonstration of using the SolarNetwork API Core and SolarNetwork Datum Loader packages.
