DEVICE isn't documented about sunsynk HOT 4 CLOSED

DEVICE is a selectable USB device in the HomeAssistant UI.

PORT should be an empty string when you want to use the selected device, otherwise PORT is preferred

from sunsynk.

But DEVICE seemingly can't be empty (which is more likely to happen if just setting via yaml), when it should be able to be when you're using one of the "proxies" or basically the RS485 adapter plugged into the device

from sunsynk.

Just select any DEVICE, PORT is preferred if present.

Yeah, I know.

But it should be at least documented to say this..
