Temperature & Humidity Sensor 10-Pack, Hub Required!

Great

Yes, these really work as advertised.

So our farm building are spread out a bit. Greenhouse, special raking systems inside greenhouse, storage rooms, open fields, pump house at the far end. And ai always know what the temperatures are. Sometimes it causes me to get up, put on a robe and head outside at midnight. And that is a good thing. Oh, and the original set of sensors has been up a couple of years.

Works all the time

Easy to set up. Everytime I open the app it works. No loading and waiting. Battery life is amazing. I have had other temperature sensors. They didn't refresh half the time and I had to change the batteries every two months. I currently have 15 temperature sensors, 11 water leak sensors and 2 garage door open/close sensors on the same hub. It all works on one app.
