Having investigated the /dev/ttyAMA0 suggestion that seems like really hard work on the RP4 as /dev/ttyAMA0 seems to be reserved for Bluetooth. See this:

If I read that correctly, you will never experience that issue on a RPI-0 so it's just me suffering if your code looks for ttyAMA0. The RPI-0-W's are out of stock at the moment so I'll just have to wait a bit unless you can suggest another way of doing this.
