    Small Gadget, Big Insurance Discount
    I didn’t buy this because I suddenly wanted to track my home’s humidity trends. I bought it because my insurance company offered me a discount—if I could show I had a fire/environment monitor. This Tapo fits that requirement, and it’s way cheaper than watching my premiums climb.Setup was easy: pop in the batteries, pair it to Wi-Fi with the app, and you’re in business. It tracks temperature and humidity in real time, logs the history, and even sends alerts if conditions change beyond your set limits. The readings matched closely with a thermometer/hygrometer I already trust, so I’m confident it’s accurate enough for both peace of mind and insurance paperwork.The nice thing about it being battery-powered is that I can place it anywhere without worrying about cords or outlets—and it keeps running even during a power outage. The downside? The app feels like it was designed for people who want to integrate it into a full smart home, so getting straight to the historical logs takes more taps than it should.In the end, it’s a small, portable gadget that paid for itself instantly through the insurance discount. Not a showpiece for your living room, but it quietly does its job while you forget it’s even there—until you need it.

    Turned my dumb humidifier into a smart humidifier
    First of all, this is much smaller than it appeared to be in the photos.Once you set everything up, you can easily set “comfort zones” for both temperature and humidity in the app allowing you to get notifications if it reads values outside of those zones. You can also set it to balanced mode, or high sensitivity mode. In high sensitivity mode it updates every .3 degrees Celsius or 3% humidity. In balanced mode it updates every .5 degrees Celsius or 6% humidity, which consumes less power.As far as I can tell, based on the available data in the app it still updates every 15 minutes regardless of this setting. The only question is how far it will be able to go outside of the comfort zone before it ignores that 15 minute interval and pushes the data, giving you an alert.For what I wanted this to do, it’s perfect. When paired with a Tapo smart plug and a “dumb” humidifier, it can automatically start that humidifier if your room drops below a specific value, and stop that humidifier when it exceeds a different value. This is exactly what I wanted to help keep my expensive guitars humidified while still using my preferred older evaporative humidifier.*update 8/28/2025*After using this in my “guitar room” to monitor my humidity, I was impressed with both the accuracy, and the alerts. The graphs of humidify and temperature over time, ease of use, and quality of alerts made me buy a 2nd one for my tuck-under garage. I live in a place that gets very cold in the winter, and I have water pipes that run through my garage. I’ve had them freeze and crack, which as you can imagine isn’t fun. Not only can I see the current temperature in my garage whenever I walk past this, I can also easily set a temperature alert that I’m confident I will get, that will let me know if it seems to be getting too cold in my garage so I can address the problem before my pipes freeze. The magnetic back on this device meant I could just stick it to one of my metal shelves, so I didn’t have to drill a hole, rely on tape, or actually do anything at all to mount it. As far as I’m concerned, this device has already paid for itself in saved worry just for that, but it’s also kept my guitars from drying out an cracking.

    Can Set Up Personalized Alerts
    The monitor works well and I am able to get alerts when outside of my settings. I purchased so we could have visibility of the temp and humdity while away, and it works perfectly for that. The temperature appears to be very precise. The humidity appears accurate, though I haven’t verified it.

    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.

    Nice temp sensor
    Works good. It shows temp and humidity on screen so you don’t need to look it up on the phone. Battery life is so so. Connects easily and works fine, but I need to figure out what’s going on with battery life.

    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!

  7. a

    it’s good but be careful that the and this device are UK or both USor they will not detect each other

  8. 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

  9. Dan

    Does the job

  10. Rocket

    Accurate, push notifications are good, can’t calibrate, not sure how long batteries are good for

  11. Ahmad Qadomi

    Good product but it doesn’t pair with EU other Tapo devices, so I had to return it.Since all Tapo are imported, make sure to buy entire system from one market, like Amazon Germany, mixing won’t work together.Amazon accepted my return and refunded me, so it was just misunderstanding, still product is great.
