July 7, 20233 yr I need to move my homeassistant from rpi4 to an opi5 but I have some I2C sensors connected. Had anyone any luck configuring python and gpio to work with I2C sensors? This was a bit rough a while ago and the kernel support seems much more limited compared to the rpi4 for this type of use case. Any experience?

However I had to update couple pin/port combinations in the adafruit libraries. I opened a PR for this added support for i2c1-m4 overlay in orange pi 5 Process was not too complicated: - activate i2c layout in overlays - I only tested i2c1-m4 - install gpio (wiringpi library) to read the pin numbers. It will show the logical pins enabled by the overlay (you need to look at the pinout diagram for physical pins) - I added a combination for SDA/SCL pins that matches the overlay and pins - needs to go in two spots in the adafruit code Btw, kudos to the new 25.8 version - it has python 3.11 out of the box.
