The Measurement class¶

class OmniPower.OmniPower.Measurement(value: float, unit: str)[source]¶: Single physical measurement. A single measurement of a physical quantity pair, consisting of a value and a unit.

The MeterMeasurement class¶

class OmniPower.OmniPower.MeterMeasurement(meter_id: str, timestamp: datetime.datetime)[source]¶

A single measurement collection based on one frame from the meter. Will contain multiple measurements of physical quantities taken at the same time.

add_measurement(name: str, measurement: OmniPower.MeterMeasurement.Measurement) → None [source]¶: Store a new measurement in the collection.

as_dict() → dict [source]¶

Serializes and dumps the Measurement frame as a dict. Make an object similar to {

“Meter ID: “: “3232323”, “Timestamp:”: “2020-10-13T17:36:53”, “Measurements”: {

“A+”: {
“unit”: “kWh”, “value”: 7

}, “A-“: {

“unit”: “kWh”, “value”: 8

}, “P+”: {

“unit”: “kW”, “value”: 9

}, “P-“: {

“unit”: “kW”, “value”: 10

}

}

}

json_dump() → str [source]¶: Returns a JSON formatted string of all data in frame.
