Use SEN0546 / cht8305 temp/humidity sensor with Pico?

Hi,

I have been using SEN0546 / cht8305 temp/humidity sensor with Arduino without too much issue.

I was hoping to be able to use it with a Pico ("how hard can it be?") - but so far not able to get any traction. I am admittedly not an I2C expert by any means.

I have been able to discover/scan the sensor with a Pico in MicroPython, but after that its all a blur. Whatever I do, I only seem to get “OSError: [Errno 5] EIO”

I would massively appreciate if anyone had any pointers or advise on the topic :)

Thanks in advance!!
