Smart Temperature and Humidity Sensor | Tapo T310

This Tapo temperature and humidity monitor has been accurate, easy to read, and simple to integrate into an existing setup. The E‑Ink display is clear from any angle, and the readings update reliably without the screen glare you get from LCD units. Connecting it to the Tapo app took only a moment, and it synced on the first try with no troubleshooting. The sensor responds quickly to changes in the room, and the app history makes it easy to track trends over time. Overall, it’s a dependable monitor with a clean display and seamless app integration.

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.One thing I'd like to note, is that this device can work directly with other TP-Link lights. Not only do I get notifications on my phone if my garage gets too cold. but I have also been able to tell it to turn on my bedroom light, make it red, and set it to 100%, so even in the middle of the night, I'll get woken up by a red light in my bedroom so I can make sure my pipes don't freeze.I also tried sticking it in my refrigerator, and to my surprise it was able to connect and update the temperature from inside the fridge.

It is so handy and easy to use!!

Super easy to setup and use, easy to see, and they see to be accurate. For the cost I would definitely recommend as a stand alone unit, but even better you can link them into the Tapo base unit to use them for automation. These are setup to allow me to turn on AC units, dehumidifier and humidifiers. They really are handy as a whole system. They are compact, but also easy to see from across the room with the display. Super cheap and great value in my opinion

Does the job

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.

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.

Works very well, battery lasts long. Great range to the hub (yes you need to get the hub for it to work).

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

Works great

Petit thermomètre hygromètre, J’ai acheté principalement ce capteur intelligent pour programmer un système de chauffage. Pour l’instant il affiche les données de ma chambre à coucher au sous-sol. C’est cool 😎

A good addition to the line of smart home devices. Easy to set up and start using
