Xiaomi Smart Temp & Humidity Monitor 3 Mini: European Launch

Xiaomi Smart Temperature and Humidity Monitor 3 Mini Lands in Europe: Smart Monitoring for a Healthier Home
Get ready, Europe! Xiaomi, the brand that’s always bringing us cool, affordable smart tech, has just dropped another winner: the Xiaomi Smart Temperature and Humidity Monitor 3 Mini. This little gadget, which got everyone talking after its China debut earlier in 2025, is all about making your home environment even better. It’s sleek, packed with smart features, and won’t break the bank. If you’re looking to boost your home’s comfort and your family’s health, this sensor might just be your new best friend. Let’s dive into what makes this tiny tech so great.
Small in Size, Big on Functionality
First off, this thing is tiny. We’re talking 53 x 45.3 x 13 mm and just 30 grams. It’s a smaller, lighter version of its big brother, the Smart Temperature and Humidity Monitor 3, making it super easy to pop anywhere – living room, bedroom, office, even your travel bag. The 2.1-inch LCD screen with its super-slim 5.1 mm bezel gives you a crystal-clear look at the temp and humidity, updating every 6 seconds. So you’re always in the loop with what’s going on in your space.
Crafted from durable, odor-free ABS plastic, it comes with a stand and double-sided tape, so you can place it on a table or stick it on the wall. Plus, it looks pretty slick – its modern design blends right in with any decor.

Precision You Can Count On
Inside this mini marvel is a high-precision digital sensor from the Swiss company Sensirion – yeah, the good stuff! It’s sensitive enough to catch even the tiniest shifts in your environment, showing temperature down to 0.1°C and humidity to 1% RH. This means you can nail those perfect conditions: think 19-27°C and 20-85% RH for ultimate comfort and health.
But it’s not just about the numbers. The Monitor 3 Mini also has these cute expressive smiley faces on its screen. They give you a super quick, easy-to-understand hint if things are good to go or if you need to make an adjustment. Even if you’re not a tech wiz, you’ll get it instantly.
Seamlessly Fits into Your Xiaomi Ecosystem
Here’s where it gets really clever: this little sensor plays nicely with the Xiaomi Home App. You can check your home’s conditions in real-time, and even look back at up to 3 months of history on the device itself, or 6 months in the cloud if you connect it to a Bluetooth Mesh Gateway (sold separately, mind you). The real magic happens with automations. Imagine setting it up so your fan kicks on when it gets too warm, or your humidifier starts if the air gets too dry. Super smart, right?
It uses Bluetooth Low Energy (BLE) 5.0, meaning it connects reliably and efficiently to your other Xiaomi smart devices. This is how you create that truly connected home, where your AC, dehumidifier, or fan can all work together to keep your environment just right, automatically.

Power That Lasts
Worried about battery changes? Don’t be. The Monitor 3 Mini runs on a CR2450 button battery, designed for super low power usage. You can expect the battery to last up to 2 years in standard mode. Want even more juice? Switch to the battery-saving mode (available on Xiaomi Home App version 10.0 or later), and you could get up to 3 years out of a single battery! Xiaomi’s commitment to energy efficiency is pretty clear here, not only saving you hassle but also being kinder to the planet.
Where to Get It and How Much?
Good news for Europe! The Xiaomi Smart Temperature and Humidity Monitor 3 Mini is starting to pop up. It’s already landed in Germany for €14.99, which is a pretty sweet deal. There have also been sightings in Hungary, though the price there is still being confirmed. Keep an eye out, as it’s expected to roll out to more European countries soon through the official Xiaomi global store and other authorized retailers.
While the European price is a bit higher than what it cost during its crowdfunding phase in China (around $4 USD equivalent), it’s still a seriously competitive option in the smart home sensor market. When you factor in its accuracy, design, and integration capabilities, it’s a no-brainer for many.

Why You’ll Love the Xiaomi Smart Temperature and Humidity Monitor 3 Mini
Honestly, if you’re serious about knowing what’s going on with your home’s atmosphere, this sensor is a game-changer. It hooks up with your other smart gadgets, it’s small and out of the way, and the battery life is fantastic. It’s perfect for tech enthusiasts and anyone just looking for a practical, affordable way to improve their living space.
Xiaomi really nails the focus on health and well-being with this device. It’s not just about tracking numbers; it’s about helping you avoid those pesky issues that come with extreme temperatures or wonky humidity levels – think breathing troubles, or even damage to your furniture and belongings.
Bringing It All Together
The Xiaomi Smart Temperature and Humidity Monitor 3 Mini is a solid step forward in home environmental monitoring. It packs cutting-edge tech, a compact design, and a friendly price tag. Its arrival in Europe is a big deal for anyone building out their smart home, offering a versatile way to keep your living space comfy and healthy.
