USB to RS485 Adapter for Home Assistant

Hi, I’m running ZimaOS on a desktop PC with an i5-7600K. It’s been running without issues so far. I recently bought a Waveshare USB-to-RS485 adapter to control an air conditioning unit for my ventilation system via Home Assistant using Modbus.

The adapter isn’t showing up in Home Assistant.

I can detect the adapter using lsusb in the SSH console. It appears as:

/dev/serial/by-id/usb-1a86_USB_Single_Serial_5AF6009532-if00 or /dev/ttyAMA0.

It seems the device needs to be addressed via the Docker settings in Home Assistant—ideally using the /dev/serial/by-id/usb... path.

I’ve tried several variations. What am I doing wrong?
