  1. Edward Hon

    The thermometer and iOS app work flawlessly, but the Alexa intregration is essentially useless. After linking the ThermoPro Home App and the Alexa account, the Alexa app will report temperature and humidity properly; However, no Echo device will recognize the ThermoPro device. Any query to Alexa to “ask Thermopro” anything will generate a response of Thermopro account linking required to enable skill. Linking the accounts does not help.

  2. Paul Moore

    I bought this to monitor a greenhouse. It has worked flawless. I have not noticed any of the noise mentioned by others. This was easy to setup and I love the free app. I can check it anywhere I have internet connection. I bought a different brand on Amazon that did not work. It was labeled WiFi, but never connected.

  3. Ricardo

    Great product. Works as advertised.

  4. DawgFood

    Almost Perfect! Only complaint is it should come with longer usb cord

    This thermometer works exactly as described. Set up with connection to wifi and Alexa went perfectly following the directions enclosed with the unit. I had hoped for a battery operated unit but this has a fan to pull in air and provide a more accurate reading. The fan is quiet and I can only hear from ten feet away if there is no other noise; even then, just barely. I plan on getting a one or two more for other areas of the house.

    First thing I’d like to say is don’t listen to the BS about the fan noise! I had to pick it up and hold it 6 inches from my head to hear it. I wish its accuracy was better it is about 6 % off and I’ll be checking with the manufacture about that. Easy setup and the app works great for what I need it is perfect for my needs and the temp is spot on, as a matter of fact I am ordering another one after I write this review. I like the fact it is a powered unit I am not hanging it on the wall so the cord coming out of the side doesn’t bother me but I can see where that could be a problem, I would rather it have a stand.
