AcuRite 00782A2 Wireless Indoor/Outdoor Thermometer, Temperature,White

Very reliable and accurate, easy to read and it lets you know when to change the batteries by blinking. It’s also very small and easy to hide.

This works fine but don't get it wet. I hung mine under the soffit, works great.

This is a fantastic little unit. I didn’t read the description carefully as it only displays in Fahrenheit. The description was clear. Other than that, it’s awesome.

Giving this 4 stars because I had one on my camper for a couple of years. I had the outside unit zip tied under the frame, and honestly I'm surprised it lasted as long as it did especially when towing through rain and dirty roads it would get covered in water & dirt and then still work when we got to the campsite, so that speaks to its resilience. Well the outdoor unit did finally die, it was all corroded when I opened it up. I ordered the same unit as a replacement and the replacement was non-functional from the start. Would not connect to the outdoor unit, indoor unit always said it was at low battery (despite trying several fresh batteries), and the LCD display had some elements that were not illuminating. I sent that one back for a full refund and purchased a more comprehensive unit that includes humidity. So, when it works, it works great, but if you get a dud from the start just send it back.
