• CO2 concentration
• Relative humidity

Installation

pip install pyzytemp

Examples

Streaming value from a device:

import pyzytemp
device = pyzytemp.find()[0]
for measurement, value in device.stream():
    if measurement == pyzytemp.Measurement.CO2:
        print(f"Current CO2 level: {value:.0f} PPM")

Polling for recent values from a device:

import time
import pyzytemp
device = pyzytemp.find()[0]
for _ in range(32):
    time.sleep(1)
    temp = device.get_last_temperature_c()
    if temp is not None:
        print(f"Last recorded temperature: {temp:.2f}C")
