That's quite a lot to go through when you want to select a shirt for work each morning.
I have an indoor-outdoor thermometer -- an indoor unit with digital display, and an outdoor unit that transmits the temp to the display via radio waves or some such magic. I put the outdoor sender in my cellar, right beside the skinny little pipe that goes to the water pump pressure switch, because that's the first thing in my house that freezes. You could do the same with your remote closet, so you can easily monitor it and see whether you have a problem or not.
