Qwiic HAT for RPi4 and SHTC3 sensors

Other
1

I have a RPi4 setup with Qwiic HAT connected to it that I am using to read 4xSHTC3 sensors.

I could only read one of the sensors sitting at 0x70. Can someone explain how can I read all 4 sensors in linux shell (using hwmon(s)) or a python script?

I can’t find a straight forward instructions for that.

Thanks

You’d just need a mux that gives them virtual addresses SparkFun Qwiic Mux Breakout - 8 Channel (TCA9548A) - BOB-16784 - SparkFun Electronics

Disable all of the i2c pull-up resistors except for one (I recommend leaving the mux’s intact/active) SparkFun Humidity Sensor Breakout - SHTC3 (Qwiic) Hookup Guide - SparkFun Learn

And then you should be good to go
