TFMini-S and airspeed sensor on I2C splitter

Hi all,
I have a TFMini-S and a airspeed sensor both works on I2C. As I’m using a orange cube plus, which has a single I2C port I have to use a I2C splitter.
When I connect either of the sensors to I2C splitter it works, if I connect another sensor none work.
Individually anyone works.
I tried powering them externally, still didn’t work.
Any idea or suggestions what’s actually wrong???


Need to know exactly which makes/models of hardware you’re using, along with ArduPilot version.

Which I2C adresses are used by your sensors?.
