Bluetooth only. Poor range, non-standard batteries in remotes. Previous model of hub and remotes much better. Very disappointed.
I live in an RV fulltime in SW Missouri. It gets really cold here in the winter (-14) and with this kit and three more sensors, I’m able to monitor all of the vulnerable areas of my 5th wheel from work. If I get an alert on my phone that an area is getting below my preset temperature, I can be home in 20 minutes to assess the situation. I love it!
I bought this to measure temp and humidity in our basement for our wine. We have a secion of our basement that is stone and seemed like a greta place to store our wine. I bought this unit and hung it in the area we would put wine. This unit is great! It was super easy to set up ont he app and instantly get reading. I can access the data from anywhere in my 2300sqft house (bluetooth). The data updates quickly and I can get a very accurate reading.
The app is great !! It works good !!
I highly recommend the wifi version of this if you want real-time updates and notifications on temps you set.
