Thanks Admin. So I made good progress!

Anybody using Atlas Scientific probes: While it works with both UART and I2C, by default the probe is set on UART.

To switch the board to I2C, follow these steps:
Interfacing Atlas Scientific Ph Sensor with Arduino via UART/I2C (how2electronics.com)

UART: led is green, with I2C activated, it's blue.

Once done, you will see your probe in the logs.

Admin: How do I connect 2 probes (I have a pH and ORP) ?

First one is connected using the I2C extender and this works fine. 
Second one: I tried using the I2C connector on top of the E16P board but it doesn't work.
