YoLink Weatherproof Temperature & Humidity Sensor, 3-Pack

excellent tool

These sensors are excellent. I have at least 8 between temp and leak and they are essential, particularly the ones in my greenhouse. The heat there only fails after about 3 AM and these will wake you up no matter where you are.

Confusing

Could not link to my wifi. Thinking about tossing it

Small but mighty

The device itself is smaller than I anticipated, but works flawlessly. The device itself is an easy 5-stars. The app is good, but not great.
