where did you connect your sensor on the TX Board? On the standard I²C or on the other one with the extender IC mounted?
The port with the extender IC is only suitable for sensors that have an integrated level shifter. It might bring other sensors to fail because of overcurrent on the data and clock bus line.

engolling,
Now that you mention it, I did connect the last sensor to the extender I²C bus as I have had issues with the TX board freezing up and not initializing when the sensor is connected to the normal I²C bus.
What I've never understood is why the sensors would work on the extender I²C bus and not on the standard I²C bus.
Both buses are connected to the same Arduino pins.
The new sensor is connected to the standard I²C bus and working fine so far.
Maybe I should look at replacing the Arduino at some stage.
