Usage of library

Current Readings Example

import aranet4

device_mac = "XX:XX:XX:XX:XX:XX"

current = aranet4.client.get_current_readings(device_mac)

print("co2 reading:", current.co2)
print("Temperature:", current.temperature)
print("Humidity:", current.humidity)
print("Pressure:", current.pressure)

Logged Readings Example

import aranet4

device_mac = "XX:XX:XX:XX:XX:XX"

history = aranet4.client.get_all_records(
    device_mac, entry_filter={"humi": False, "pres": False}
)
print(f"{'Date':^20} | {'CO2':^10} | {'Temperature':^10} ")
for entry in history.value:
    print(f"{entry.date.isoformat():^20} | {entry.co2:^10} | {entry.temperature:^10}")

Library functions

get_current_readings(mac_address: str) -> client.CurrentReading

Get current measurements from device Returns CurrentReading object:

class CurrentReading:
    name: str = ""
    version: str = ""
    temperature: float = -1
    humidity: int = -1
    pressure: float = -1
    co2: int = -1
    battery: int = -1
    status: int = -1
    interval: int = -1
    ago: int = -1
    stored: int = -1

get_all_records(mac_address: str, entry_filter: dict) -> client.Record

Get stored datapoints from device. Apply any filters if required

entry_filter is a dictionary that can have the following values:

• last: int : Get last n entries
• start: datetime : Get entries after specified time
• end: datetime : Get entries before specified time
• temp: bool : Get temperature data points (default = True)
• humi: bool : Get humidity data points (default = True)
• pres: bool : Get pressure data points (default = True)
• co2: bool : Get co2 data points (default = True)

Returns CurrentReading object:

class Record:
    name: str
    version: str
    records_on_device: int
    filter: Filter
    value: List[RecordItem] = field(default_factory=list)

Which includes these objects:

class RecordItem:
    date: datetime
    temperature: float
    humidity: int
    pressure: float
    co2: int

class Filter:
    begin: int
    end: int
    incl_temperature: bool
    incl_humidity: bool
    incl_pressure: bool
    incl_co2: bool
