Thank you! Still don’t have anything but should. Could’ve used it this last summer.
While I have not tried putting one in the freezer, the Wyze climate sensor seems to have no issue with my refrigerator (circa 1991). Works fine. Likely the battery won’t last as long because of the cold? Hasn’t been a problem so far, but we’ll see! Does exactly what I want. [I should probably also put one of the leak sensors in the bottom of the fridge (to tell me when the drip tray drain is clogged)! ;]
