Probably not worth the time/headache. Should be sufficient to put a sticker with the send/receive IP's on the box and maybe make an API over ethernet where you can change the outbound IP's if it's trivial.
Not being a plant expert, I don't know what data rate makes sense, once an hour? I can make it configurable.
At least ten time per second or so, and do make it tunable. No reason to cut bandwidth for no reason – we believe in keeping as much data as possible for as 'long' as it's practical (just don't send at max speed / w/o delays!)

Great, then you're set.

UDP is preferred.

Great! Thank you. This is a nice surprise for me – I assumed I was going to have to do this in September/October.
Cheers,
