Weatherboard compatible humidity sensor

I have purchased and installed the Adafruit SHT31 humidity sensor.

It appears at 0x44 on the i2c bus and by running a small python script I can read the temperature and humidity.

I have not been successful integrating this into the software. It makes sense to get the humidity readings into  outsideHumidity in the driver software, but i have not been able to figure out how to do this.
Any help or suggestions will be much appreciated.

# Setup SHT31
# turn I2CBus 1 on
if (config.TCA9545_I2CMux_Present):
tca9545.write_control_register(TCA9545_CONFIG_BUS1)

###############
# Detect SHT31
try:
# Get I2C bus
bus = smbus.SMBus(1)

# SHT31 address, 0x44(68)
# Send measurement command, 0x2C(44)
# 0x06(06) High repeatability measurement
bus.write_i2c_block_data(0x44, 0x2C, [0x06])

time.sleep(0.5)

# SHT31 address, 0x44(68)
# Read data back from 0x00(00), 6 bytes
# Temp MSB, Temp LSB, Temp CRC, Humididty MSB, Humidity LSB, Humidity CRC
data = bus.read_i2c_block_data(0x44, 0x00, 6)

# Convert the data
temp = data[0] * 256 + data[1]
outsideTemperature = -45 + (175 * temp / 65535.0)
fTemp = -49 + (315 * temp / 65535.0)
outsideHumidity = 100 * (data[3] * 256 + data[4]) / 65535.0

# Output data to screen
#print "Temperature in Celsius is : %.2f C" %cTemp
#print "Temperature in Fahrenheit is : %.2f F" %fTemp
#print "Relative Humidity is : %.2f %%RH" %humidity

outsideTemperature, outsideHumidity = sht31.sense()

except IOError as e:



       #    print "I/O error({0}): {1}".format(e.errno, e.strerror)

       config.SHT31_Present = False


I am trying to modify the GrovePi.py driver which supplies all the sensor information to the weewx database. The code above was inserted just before the "Setup AM2315" section but I amstill battling with syntax errors. 

The GrovePi driver is just a simplified version of the GroveweatherPi driver on the Switcdoc github site.
There is no Arduino, my weather station uses the Grove Weather Rack board and the software runs fine.

I am trying to add the SHT31 humidity sensor which is connected to the I2C bus at address 0x44.

The software excerpt I sent you, provides temperature and humidity readings from the sensor when run from a SSH terminal.

The problem I have is to how incorporate this software in the GrovePi driver to display the readings.
