Luckily I've never been in the situation where I've been below 65, at least not a lot, and not when I'm filling tires.

I've read other posts from Poggers who have external sensors who have been woken in the middle of the night (cold night) with a low pressure alarm from their system. That's never happened to me, and I'm guessing that even though SmarTire suggests never filling less than CIP, it nonetheless does compensate downward with a lower pressure than the 65 degree pressure.

Next time it's less than 65 out, I will check the monitor, just to see.
