I'd like to configure and test as much as possible prior to recieving the 485 and physically hooking it up. Is it possible? Thanks in advance, for any responses. |

Not really. It’s dependent on a tty serial port being available. You can plug any old USB adapter with serial chip in the raspberry that makes the port available. (Ie any hardware to get /dev/ttyUSB0) Then AqualinkD will start and you could do a few things, but it will quickly fail if it doesn’t read anything on the serial port after 30 seconds or so. |

I'm going to use the waveshare USB/ETH hat on the pi zero 2w. Is that or something simular what ppl are using? This one: https://www.amazon.com/USB-HUB-HAT-Board-Compatible/dp/B07X1BH5FN |

@twack that waveshare hat won't give you tty-to-rs485. I tried waveshare's rs485 can hat but it only interacts with the Aqualink bus at 3.3v. I needed 5v so this didn't end up working for me. I ended up using this and powering it via the 5v gpio pins on an orangepi |
