Hello everyone, I hope this message finds you all well! I’m Bartosz, a new member of this community, and I’m reaching out for some help with an issue I’ve encountered after updating my Home Assistant setup. I’m running HA on a Raspberry Pi 4 using Docker, and after updating to version 0.115, my MCP23017 expander stopped working for both sensors and switches. This was working perfectly before the update, so I’m a bit puzzled about what’s gone wrong.
Here’s a snippet of my configuration for reference:
yaml
Binary sensors
binary_sensor:
- platform: mcp23017
i2c_address: 0x22
pins:
0: MCP_IN_8
Switches
switch:
- platform: mcp23017
i2c_address: 0x20
pins:
0: MCP_8
For the sensor, I’m getting the following error:
python
Error while setting up mcp23017 platform for binary_sensor
Traceback (most recent call last):
File “/usr/src/homeassistant/homeassistant/helpers/entity_platform.py”, line 193, in _async_setup_platform

elif chip_id == ap_chip.STM32:
AttributeError: module ‘adafruit_platformdetect.constants.chips’ has no attribute ‘STM32’
The same error occurs for the switch setup. I’ve tried rebooting my Raspberry Pi and reinstalling the necessary libraries, but nothing seems to resolve the issue. Has anyone else encountered this problem after updating to HA 0.115? Any suggestions or insights would be greatly appreciated!
Thank you all for your time and assistance. I look forward to hearing from you!
Best regards,
Bartosz
