WiFi Temperature Sensor with Waterproof External Probe,Tuya Smart Temperature Monitor with Backlight LCD Display,Rechargeable Battery,Remote Monitor for Freezer, Refrigerator, Fish Tank

Works well. Alerts me if my oil fired hot water tank shuts down because of fault. Smartlife app integrated easily. Google Home tells me if a problem arises.

I bought this sensor to monitor my HVAC temperature output at the furnace which is under the house. The sensor works within a degree of other sensors and connected to my wifi without issue. The issue with this product is the Tuya Smart App. The graphing feature doesn't plot all datapoints. Temperature history is only for the current day. if you go back to the previous day, no data is displayed. I attempted to "export" data, I entered my email address (they call it 'mailbox') and hit save... I get "please check your input and retry"...it apparently doesn't accept emails...though during setup, a verification code was successfully received to the same email address. The forward /backward arrows to view temperature history went backward, but plotted NO DATA! When I attempted to go forward to the current day, the arrow was unresponsive. I bought this expecting to view and export data equal to the sensing interval...No Can DO! You have to close the app and reopen to return to the current day. FAQ/Feedback is useless. When you click "Unresolved?Send Feedback" it offers pre-selected question types. Clicking "Other" opens another window with a "0/2000" character counter, but no way to type text. This APP does not compliment the sensor. I'm returning it.

This unit works great in my garage to monitor the temp in a freezer. We just need to know if the freezer looses power and starts to warm up.This unit has been work perfectly for about 2 months so far. The wired probe goes into the freezer. The unit itself is attached to the side using the included magnets. Then it plugs into the wall for power.The app instructions were not written that well, just a rough Chinese to English translation. But with a bit of common sense it sets up similar to many other IOT devices. Took all of 15 minutes to get it working.It is well thought out. There is even a built in back up battery. If the power fails and our freezer starts to thaw it uses the battery to alert us through the wi-fi connection.I definitely recommend this product.

We use these on our freezers. Love that they alert your phone when the temperature goes up. Occasionally though the app is slow to update which can cause issues.

Using in walk-in cooler. Frequently gives false alarms. Not very recommended.

Exelente dispositivo me encanta funciona muy bien

Installed as per instructions.Tried several times to set up Bluetooth and or wifi as per instructions. It's just a digital thermometer. Non of the rest works.

I love that it works with the Smart Life app because I have outdoor lights on the same app. My husband has left our freezer in the garage open just enough to ruin food more than once. Won’t happen again! I set it to notify me of the temp goes above 37, and it is doing just that! I also love it has a magnet on the back to mount on the outside door so we can see the temp anytime. Great purchase!
