Help me please Sensor SHT20 SHT21

[Wolli01]

Who can help me?
I have the sensor SHT20 and SHT21 on ic board.
How can I read it with the Wipy/Lopy?
Is there a library like the one for the Bosch BME 280 ?
What I have found only comical values come out and no numbers.

#Init bus
i2c = I2C(0, I2C.MASTER,  baudrate=100000)

#SHT20 Temperature command (use no hold master only commands --> 0xF3 )
command = array.array('b', [0xF3])
result = array.array('b',  [0, 0, 0])
print(result)

print(i2c.writeto(0x40, command))
time.sleep(0.1)
result = binascii.hexlify(i2c.readfrom(0x40, 3))
print(result)```

Ergebnis = b'63acf9'
