Today's motor temps
Based on this, I've programmed it to not start when the motor is > 45C. Summer temps here are typically below 38C , and on rare occasions up to 44C. So 45C may not be enough of a gap on a blazing summer day, although the porch will be some cooler. We'll see. I could factor in the outside air temp, but want to keep this simple (hah!).
Also put in my own thermal shutdown at 70C which I'll adjust down when I have a better idea of the normal range, but I expect the compressor has a better one built into it so if mine triggers it's probably on fire.
