I just got back from a 3 week Mexico beach trip and I took the advice of someone on this great forum and installed a wireless thermometer in my frigde. I am always worried that the temp feels warm. I purchased one of the units that gives the most recent 24 hour high and low temps and let it do it's thing. Sure stoppped the dreaded open and closing to check the temps. Must be an OCD thing. With the weather station sitting on the counter it reassured me the temps were good. Now if I could only find a wireless light detector to tell me if the light is off when I shut the door.

Paid less than $25 for the weather station.
