Product review (1 stars): App sucks, connection sucks, probably returning
Being that it's 2016 I would think that something like this would work right out of the box no problem. Boy was I wrong. This took forever to connect and start getting readings, which didn't update properly for about 45 minutes. Awful. We stuck one of the sensors in the refrigerator and it took about 40 minutes for the update a change in temperature not even the correct temperature of the refrigerator. I have yet to talk to technical support, but I have a feeling it's going to be a waste of time. All the other Wireless technology my house works flawlessly with very little interference from the microwave and other conflicting devices. When I do a speed test from the same location as the sensors, I'm getting 30 down and 25 up, so it's not like they can't connect to the receiver. I had the app work once for an hour on my s6.  Then I couldn't get it to reconnect after uninstalling and reinstalling. The web interface works well, but doesn't update well at all.  I will most like return this for a non-wifi triple sensor system and live stream the monitor via an old smart phone on a tripod using Alfred.
