After years of running the Tado V3 smart heating system, I finally made the jump to Tado X. I figured it would be a solid upgrade. What I didn’t expect was just how much smarter, smoother, and more refined this system would be both in daily use and in the results it delivers.
Let’s set the scene: I live in a four-story house, about 15 years old, heated the traditional way radiators in every room, no fancy heat pump, no underfloor tech. To manage the climate properly across all levels, I installed 11 radiator thermostats and one smart thermostat in the living room. Installation? Surprisingly easy. The app walks you through pairing each device, and everything was connected and working within an hour. Zero technical drama.
Do You Need a Bridge?
Tado X uses Matter, a new smart home standard that allows devices from different ecosystems (Apple, Google, Amazon, etc.) to work together seamlessly. It’s great for future-proofing and improves energy efficiency and responsiveness.
But here’s what I found out: you still need a Matter hub to make it all work. I initially tried using a hub I already had at home, but it couldn’t reach all four floors reliably. So I ended up using Tado’s own Matter bridge, which solved the range issue instantly. Everything’s been rock-solid ever since.
No More AA Batteries: Hello USB-C
One of the most frustrating parts of the old V3 system? The constant AA battery replacements. In a big house with 11 devices, it felt like I was always one step away from another low-battery alert.
Tado X completely fixes that. The new radiator thermostats come with rechargeable batteries, and when they run low, you just top them up using USB-C. It’s simple, fast, and far more sustainable. I haven’t had to recharge them yet, but knowing I won’t need a drawer full of AA’s anymore already feels like a win.
Smarter Automation with Auto-Away
With little kids in the house, I appreciate any system that runs smoothly in the background and Auto-Away does exactly that. It tracks both my phone and my wife’s to detect when we’ve left the house, and automatically switches the system to Away Mode. No more manually turning down the heat or second-guessing if the system is still running while we’re out. It’s just… handled.
25% Energy Savings in One Month!
In March 2025, Tado X helped us save 25% on energy. This wasn’t just a nice round number either the app breaks it all down: 146 hours in Away Mode, 186 hours of weather-based temperature adaptation, 82 times the system turned off heating when a window was detected open, just 0.3% of manual adjustments. One-third of those savings were driven by Auto-Assist, which I barely touched after setup. The system ran itself.
Designed to Blend In and Stand Out
Aside from the tech, there’s something else that matters: design. The Tado X devices look clean, minimal, and modern a big step up from the older V3. The displays are brighter and easier to read, especially in low light, and the controls feel more intuitive. It actually looks like a smart device, not something borrowed from an industrial boiler room.
Final Verdict: Tado X Is the Upgrade V3 Never Was
If you’re still on Tado V3 — or just getting started with smart heating in a larger home — Tado X is the system you want. Yes, you’ll need a Matter hub, and in my case, Tado’s own bridge was the only one that reached all floors reliably. But once that’s in place, the whole experience is next-level.
