  1. Rob Robinson

    Mt TP90 reads about 5 degrees hot. Can this be adjusted?

    • CSTEAM (store manager)


      Unfortunately, the TP90 cannot be adjusted.

      Please contact our service team at for assistance.

  2. Carl Armour

    Can you buy this in the UK? Can it be shipped, if not. It’s exactly what I’m looking and after buying other models, I only want to purchase this make and model.

    • CSTEAM (store manager)


      Unfortunately, this is not currently available in the UK.

  3. Jason Baxter

    Is there any way to do threshold alerting to the app?

    • CSTEAM (store manager)


      Unfortunately, the ThermoPro Home App which the TP90 is not currently able to set alarms at certain temperature thresholds.

    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.

  5. Ricardo

    Great product. Works as advertised.

  6. DawgFood

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

  7. freefalldenver

    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.

  8. Ted

    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.
