I finally got Mozart to read the room temperature and turn on the A/C when it was too hot. The missing link was the define for target temperature was never initialized. I'm not sure how this got through the compiler. I started the conduit in the garage by threading wire into 10 foot lengths. It looks like I'll need 60 feet of wire times 2 to do the job.
Incredibly tired today, took a nap at 5:30 pm. Dinner was chicken fingers with corn mach choux and a single glass of Shiraz.
