      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'
