Smart weather station Sencor SWS 12500 now costs under 4 thousand. It measures wind, temperature, precipitation, UV, and humidity

If you want to know the exact weather in your garden, not just an estimate from the forecast, a professional weather station is the answer. You can now get the Sencor SWS 12500 WiFi with code SENCORMINIDAYS20 for 3,992 CZK instead of 4,990 CZK. It’s a capable device, but it has its specifics, so let’s be upfront. Before purchasing, it’s a good idea to check the price and availability in detail on Alza.

Quick summary:
✅ Makes sense if you want a professional weather station with extensive measurements, a large display, and online data publishing — and you don’t mind a bit of tweaking.
⚠️ Consider that WiFi and cloud setup is challenging (owners report up to an hour and a half), it’s controlled via web (not a proper app), and outdoor sensor installation requires improvisation.
💡 For 3,992 CZK you get a lot of data for a reasonable price — if you’re a technical type who likes to fine-tune things.

Why this weather station is interesting

The main draw of the Sencor SWS 12500 is its 7-in-1 outdoor sensor, which measures wind speed and direction, rainfall, temperature, humidity, light intensity, and UV radiation — almost everything a professional station can do, within a range of 150 m. Plus, a large 8.4″ color display and the ability to publish data to Weather Underground and Weathercloud. For DIY enthusiasts, gardeners, and weather aficionados who want precise local data rather than a general forecast, it’s an attractive package at a reasonable price.

Key parameters explained in plain language

The number of measured values is impressive: in addition to indoor and outdoor temperature and humidity, you get barometric pressure, UV index, sunlight intensity, precipitation total (hourly to total), and complete wind data including the Beaufort scale. The display also shows time, moon phases, sunrise and sunset, and a 12–24 hour forecast. The system can handle up to 7 sensors, so you can monitor multiple locations at once. Power is handled by an adapter (main unit) and batteries (sensors) — here’s a caveat: the outdoor 7-in-1 sensor runs only on batteries, and one owner changed them every four months, so lithium batteries are worth it.

What users say and what to watch out for

Hodnocení je dobré: 4,6 z 5 od 82 zákazníků, 90 % doporučení, reklamovanost nízká (2,46 %). Spokojení majitelé chválí přesnost měření, čitelný barevný displej, dosah čidla a množství dat. Ale teď to podstatné, protože se to opakuje a pro technicky méně zdatné je to zásadní. Nejčastější výtka míří na nastavení WiFi a připojení k cloudovým službám — víc majitelů uvádí, že jim to trvalo hodinu a půl i s návodem, a jeden píše, že to nedokázalo dát dohromady pět lidí. Souvisí s tím druhá věc: nemá pořádnou mobilní aplikaci, vše se konfiguruje přes webové rozhraní, což někteří označují za „pravěk”. A do třetice praktikálie: montáž venkovního čidla vyžaduje improvizaci (držák není ideální, čtvercový tvar se špatně natáčí na sever). Jedna extrémně podrobná recenze rozebírá desítky drobných softwarových nedodělků — stanice zkrátka není doladěná do detailu. Pár lidí taky hlásí poruchu venkovní jednotky po několika měsících až letech.

When it doesn’t make sense

If you want a simple “unpack and use” device and don’t enjoy tweaking WiFi and the cloud via a web interface, this one will disappoint you — get a simpler weather station without online features. Similarly, if you’re mainly concerned with outdoor temperature and nothing else, you’ll be paying for dozens of features you won’t use (as one owner admits). And if you want a convenient mobile app, you won’t find it here. However, for a technically savvy enthusiast who wants to play with data, publish it online, and doesn’t mind initial setup, it’s a capable station at a good price.

Do you want a professional weather station with online data, even at the cost of more complex setup, or would you prefer a simple “plug and play” one?
