So I was walking through Walmart today and saw these Hygro's that have a wireless display. There is a box that you mount wherever you want and a display that would work up to 300ft away. I was just wondering if anyone has used something like this in a humidor. Something like a cooler or even a cabinet without a glass front just so they didnt have to open the humidor every time they wanted to check the Rh. They have a good price at like $24.
