Review on MOCREO WiFi Thermometer Hygrometer: Remote App, Email Alarm & Data History - Wireless Indoor Monitor for Freezer Alarm, Home Greenhouse, Garage, Wine Cellar - 3 Pack by Donald Phillips

Bought to control temperature in garage fridge/freezer. The setup was a little painful because I wasn't patient. Connecting to my wife via the app was very easy, but connecting the temperature sensors gave me some headaches. Nice guide in the app to wake them up and then just be patient. It takes a few minutes for the app to detect your presence. I played with it for a while, then turned everything off and emailed the company for support. They played their replays very quickly and said they looked like they would work, but the system was disabled (I disabled it). The next morning I plugged it in and everything works great. I also swear that customer service was quick, polite and very helpful.
