Product review (5 stars): Works Great!! Recommended..
I added this device to my SmartThings hub. It was a little tricky to add, but it can be done. I read all the reviews about the product not being very accurate and conducted my own testing using various digital temperature readers. My device showed to be 0.5 +/- off. A half of a degree is not enough for me to worry about. I use this sensor at my vacation home in the well/pump house combined with a Z-wave outlet to regulate the heating. I learned the hard way that a space heater thermostat is untrustworthy last year with busted water pipes. I like the fact that this sensor has a digital read out on it so you don't need your app to read it and it has a backlight that comes on for dark spaces when you push a button. With this device connected via the hub I setup a SmartApp to kick the heat on when the temp reaches X degree and off at Y degree. It works great and has saved me a considerable amount of money on the electric bill plus I know at a glance that my pipes won't bust. I highly recommend this sensor to anyone looking for a temp/humidity reading in a space that is not exposed to outdoor elements.
