What we know:
- UNO green LED on: power good
- UNO amber LED on: script ran far enough to turn on IO13 (to the "blink" LED).
- BrewPi host can't talk to the Uno suggests the comm lines aren't working.
So, unsolder the wire from IO1, make sure the IO 0 and IO 1 pins aren't shorted to any neighbors, then see what happens....
Cheers!
