I have a temperature probe I use to monitor my hot tub. It had two components the transmitter which lives in the cabinet and a waterproof probe that comes out and goes into the water of the tub. I've been following the temperature and the water temperature is fairly steady (39c or 102f), but the temperature where the transmitter is inside the cabinet is getting uncomfortably cold (8c or 46f). Outside air temperature right now is cool but not that cold (-2c or 28f) but there is a fairly stiff wind today. It's not even winter yet so I'm a little worried that if it gets colder out (and it most certainly will) the temperature in the cabinet could go before freezing and the lines could start to freeze.
Should I be worried? How cold is too cold for inside the cabinet? Is there anything I can do to help keep it from getting too cold?
