Hi, I am really interested in hard wired systems using GPIO pins, no issues there. The problem is when i try to integrate the MCP23017 chip using i2c port. I tried several methods and went through many forums but i just can’t find a way to configure it and get it working. Is there someone that managed to do so? I edited the config file to enabled the i2c port, but then when it comes to select the platform it always says that it is not recognized.

The third topic looks promising.
And there is also something to use it with esphome.
