Reasonable Price, Extremely easy Setup, Highly Accurate
I’ve tested a number of temperature / humidity sensors, they all had failed miserably. The TP-link Tapo sensor is awesome, extremely easy to set up (you do need a Tapo hub). I connected it with Alexa and set up a routine to control ventilation fans to the built in refrigerator. It works seamlessly and controls temperature great. I read some negative reviews regarding accuracy, so I tested it against the temperature control inside the refrig, it varied by only .1 degree F. Over the past 7 years I’ve converted the house to total automation (garage door control via vehicle and phone, smart irrigation of lawn and plants, motion sensing light control, smart HVAC systems, smart outlets, smart light bulbs, smart switches), trying a multitude of brands and throwing away a number of devices that just didn’t have the quality or features required. I have refined my system down to Tp-Link / Tapo / Kasa, Tailwind and B-hyve for my home automation.

Excellent Temp/Humidity monitor with large display
The TP-Link Tapo Smart Temperature and Humidity monitor is easy to setup with the Tapo app (free download) and hub (sold separately). The unit has a very large e-Ink display that is clear to see at various angles. Note though that it needs ambient light, since there is no internal backlight for night visibility. Besides the Temp/Humidity there is also a small battery indicator useful for preventing unexpected outages. In the Tapo app the sensor shows not only the current values but also a plot of Temp/Humidity vs. time for checking how the room climate is changing with time. Additionally, a comfort zone (min/max T and R.H. values) can be defined in the app, so that the app sends push notifications when the room climate is out of the comfort zone.As part of the Tapo smart system, the Temp/Humidity monitor can be used to set up smart actions with other Tapo devices, such as switching a Tapo switch on/off to control a fan or small space heater based on room temperature variations. Overall the TP-Link Tapo Smart Temp/Humidity monitor is an excellent addition to smart home automation projects.

Perfect little device does what it set out to do!
Thoroughly impressed by these sensors. The unit is small in size, but the relatively large E-ink display is vivid and easy to read from distance. The accuracy and consistency across the 3 devices I purchased is impressive. I set them up next to each other for the last couple of days and they are all displaying within +/- 0.1°F and 1% relative humidity of each other and many times all exactly the same readout. The hub is on a different floor and there’s no issues with connectivity. Compatible with Home Assistant through the required hub which can be linked through the Tapo server or locally with Matter (beta as of this review). Tapo app is easy to use if you want to use their ecosystem.Overall I feel it’s a great value versus some of the competitors!

Excellent indoor environmental sensors
Tapo Hub required. Not a big deal, though, because the hub is cheap. These temp and humidity monitors are not cheap – but the high quality (including the excellent screen) and app-connectivity make it worth it. I find these more consistent and accurate than most cheaper temp and humidity sensors, too. We have four in total. The ability to look at trends in temp and humidity throughout a 24 hour cycle in several places in your home helps a lot with heating, A/C and humidification strategy. No regrets on this purchase, especially as it’s a natural extension of the excellent Tapo smart home system we already enjoy.

Great for tracking outdoor temps (green house, garage, service porch, livestock)
I love TP-Link products. On whole I have been using them for 20+ years, and have had a very good performance and endurance of each TP-Link product from lightbulbs, outlets and switches, to Wi-Fi extenders, and now sensors. I like these TP-link tap sensors better than Ring’s hub based sensor, because tapo are easier to install and maintain, and seem to perform much more consistently. I have this particular model in my covered poultry run (chicken house) and I find it to be very accurate. The only hiccup was that one of the three tapo sensor I received had a CR2450 battery that immediately needed to be replaced. But the other two tapo sensors same with good batteries.

Perfect little smart monitor
When paired with the smart hub, this is a fantastic little smart monitor. The screen is very easy to read and updates fairly quickly. Being able to monitor the temperature and humidity throughout the day with graphs in the Tapo app is great, and you can also set it to trigger actions if temperature or humidity gets outside of your set parameter (such as use one of the Tapo smart plugs to turn on a fan or a humidifier, if your humidifier turns on with power applied at least).

Works perfectly
I got one of these and some Tapo water sensors for my basement. All the Tapo products work effortlessly. The app is intuitive, and everything connects and works just as expected. The monitor is small, great looking, and accurate. I particularly like the look of the e-ink display.I wanted something to remotely monitor the humidity in the basement (and less importantly the temperature), and this works perfectly for that purpose. I could have gotten the model without the display, but for a few bucks extra, I like this one better. In fact, after having the first one for a few months, I got another one for the living room.One note: it took about a day before I could see the readings in the phone app from outside my house. And, I hope they eventually release one with a clock.

Amazing product. I have a $1,600 fridge that will freeze all the food in the fridge. I could not get it fixed or serviced; it needs to be replaced. In the meantime, I used this sensor in the fridge on “power save” mode. I connect with the Tapo hub and use the Tapo app to automate a TP-Link (Tapo) smart wall socket to cut the power to the fridge when the temperature reaches 1.5 °C and powers the fridge back on when it reaches 3.5 °C. The battery will last for months. I will be purchasing a replacement fridge soon, but this saved my pocketbook and my sanity.

it’s good but be careful that the and this device are UK or both USor they will not detect each other
Rcd –
If you have a HUB for EU/UK, the US sensor will not work, make sure you buy the HUB and sensor devices for the same region
