Just a note: Connect the SHT31-D sensor only to the I2C port on the TX interface. If you need to use a long cable (more than 2 or 3 meters) you can use the Extended I2C port, but in this case you will need to use another I2C bus extender chip at the end of the cable. Connecting the SHT31 sensor directly to the EI2C port will reduce their life significantly.
Some older models of the SHT31 modules have level shifters on the module board, these ones (realy hard to find nowadays) can safely be connected directly to the EI2C port without using a second I2C bus extender chip.
