Arduino to Pi (Home Assistant)

Hey folks,
I have scoured the internet for a solution and decided to create an account to ask you fine people! I have an Arduino Uno r3, I have wired 2x maxx6675 thermocouples to it. I coded the Arduino and got it to spit out two readings when I open the serial monitor!

So the two problems I think I have are:

1. How to get the Raspberry Pi to read that Arduino data over USB connection?
2. How do I get Home Assistant to get that data and show it as a sensor?

If it is too difficult to answer, that’s ok. At least I hopefully can better state my problem! “A problem well stated is a problem half solved” <and I don’t know the lingo well enough to well state it haha.

Thanks!
Dave
