Best seller lists are useful, but they are easy to overread
Amazon.it Best Sellers are a decent place to start, but a bad place to stop. They can show you what shoppers are buying today, which categories are active, and which devices are easy to find in Italy.
The trap is treating popularity like proof. A smart-home device can become popular because it is cheap, discounted, familiar, heavily promoted, or easy to understand from a thumbnail. None of that tells you whether it will work calmly in your home after the first setup weekend.
The list does not know your apartment
A bestseller page does not know if your router is already overloaded, if your entry door can be drilled, if your family hates voice control, or if you are the person who ends up fixing every disconnected gadget on Sunday evening.
That is why the right move is to use bestseller rankings as a map of activity, not as a shopping verdict. The list can help you notice what exists. Your home still decides what deserves to stay.
Start with the problem, then open the ranking
For robot vacuums, do not start with the rank. Start with the mess. A home with one short-haired cat, hard floors, and open rooms is not shopping for the same machine as a home with two dogs, rugs, dining chairs, and litter tracking near the hallway.
For smart plugs, the bestseller list can be more helpful because the category is simpler. Still, the top plug is not automatically the right plug. In Italy, size matters. A bulky plug can block the neighboring socket, and energy monitoring only helps if you actually plan to look at the numbers.
Be extra careful with cameras, doorbells, and hubs
Security cameras and video doorbells are where popularity can mislead quickly. A device may sell well because the headline feature is clear, while the real decision lives in storage, alerts, subscriptions, privacy controls, and whether installation is realistic for your doorway.
Smart hubs have their own version of the same problem. A popular hub can still be the wrong anchor if it pushes you into an ecosystem you do not enjoy using. Matter, Thread, app clarity, family usability, and language support matter more than a bestseller badge.
Use the list, then slow down
Before buying from any bestseller page, ask one boring question: can you explain where this device will live, who will use it, and what might annoy you after the novelty fades?
If the answer is vague, keep browsing but do not buy yet. The boring pause is often what saves a smart home from becoming a drawer of disconnected bargains.
