Everyone has their own morning routine. Some of us go for a run, others get the kids ready for school, some just want to know if it will be smooth sailing during their rush-hour commute. The weather can throw a monkey wrench into any of those plans.
Owning a personal weather station is one way to stay on top of mother nature. Yes, you can open an app, but the information there is from a remote station miles away and up to an hour old. With a home weather station, you get up-to-minute information on what she’s up to doing right outside your door.
We went hands-on with two players in this space. Either would be a good choice for both casual observers and would-be meterologists, but one shines as the best choice for the smart home. We will add to this coverage as time goes on.
Best weather station: Netatmo Weather Station
Netatmo’s Weather Station is our current favorite. While it does come in on the pricier side—$180 for just the control unit and one temperature/humidity sensor alone, and then and additional $80 for the rain gauge and $100 for the wind gauge—it is the weather station of choice for the connected home.
Netatmo works with Samsung’s SmartThings platform and IFTTT (If This Then That) right out of the box, allowing you to do all kinds of cool things, such as control your thermostat based on outdoor temperature, or flash your Philips Hue lights if it starts to rain. The app allows immediate access to your data at anytime, and your data is shared worldwide through a special webpage and Weather Underground. It even has a sensor to measure air quality, based on the amount of CO2 present in the room it’s in.
It does have its quirks though, like a humidity sensor that is easily saturated during wet periods, and sometimes finicky connectivity with older Wi-Fi routers. But its accuracy is top notch, and the issues not bad enough that we’d go elsewhere.
Oregon Scientific Wireless Pro Weather Station WMR89A
If you’re not concerned with smart-home connectivity, Oregon Scientific’s WMR89A delivers reliable performance. At $170, it’s half the price of fully tricked-out Netatmo system, and it offers some features the Netatmo doesn’t, including optional UV index reporting (to measure ultraviolet exposure).
The console can also store up to a week’s worth of data without having to connect to your computer. That said, the station cannot currently upload data to third-party services such as Weather Underground, and the official software isn’t the best—but it is a much better option than the junk you’ll encounter at the typical big-box store. It’s also the only one at this price point we know of that can be expanded beyond basic weather measurements.
How we tested
We test weather stations over a period of at least one month to ensure we get the widest possible array of weather conditions to see how the station performs. We paid special attention to ease of use and installation, and also used nearby National Weather Service stations to judge accuracy.
Weather conditions can vary dramatically in just a few miles, so with temperature we judged readings of within plus-or-minus two degrees, and all other measurements within a five percent tolerance of the NWS station as accurate.
Finally, we examined durability. With instruments being out in the elements 24/7, this is a very important factor to consider.
What to look for when shopping
At a minimum, a basic weather station should report temperature and humidity, inside and outside your home, and barometric pressure outside your home. A mid-priced station will measure wind speed and direction, as well as rainfall. A high-end model should deliver all of the above, plus other specialized measurements such as UV index, soil moisture, and water temperature (think your pool or a koi pond, for example).
As with any product, spending more money doesn’t necessarily guarantee you’ll get a product, but we’ve yet to find a cheap weather station deliver genuine value. The vast majority of the budget stations available at chain discount and hardware stores are inaccurate. While temperature is generally accurate to within a degree or so, humidity is poorly measured, and readings can be 10 to 15 percent off actual values.
Mid-range and high-end weather stations are typically much better, and in my experience never more than about five-percent off most of the time.
Wind and rain measurements are very useful, especially if you have activities affected by that type of weather. High-end stations are nice to have if you can afford them; they’re typically the most accurate, but unless you need specialty measurements—UV, soil moisture, and the like—don’t spend the money.
Here are some other features you might want to look for in a weather station:
Accuracy: By far the most important, accuracy is also the hardest to gauge. Here we’d recommend looking at the spec sheets and choosing stations with low margins of error. Additionally, look through user reviews (or ours) for real-world testing. Not all weather stations are built the same, and a high price doesn’t always mean high quality.
Battery or solar power? Just about all weather stations these days operate wirelessly, so your instruments will run on either battery or solar power. Avoid stations that rely mostly or solely on solar power, as a few dreary days can prevent the instruments from have energy stored to do their job. Battery-operated or solar-assisted units are the best choice—you might need to change the batteries once a year.
Internet Connectivity: If your weather station can connect to the Internet, you’ll not only be able access it while you’re away, typically through an app or a special website, but you’ll also be able to share your data with the world via services such as Weather Underground. Meteorologists might need your data, especially if you’re in a place where their weather stations aren’t!
Smart-home support: Personal weather stations can make your smart home even smarter. If you already own a connected-home system, look for a weather station that’s compatible with your setup. Some stations now support automation services like IFTTT, so you can turn on your heater when the temperature gets too cold, or your A/C if it gets too hot.
Expandability: Your weather station might suit you fine now, but your needs could change later. Instead of going for all the bells and whistles up front, save some cash and buy mid-range product that can be expanded with new and different sensors down the road. That way, you’ll never outgrow it.
Durability: The elements can be harsh, and your sensors will be in it 24/7. Inexpensive stations are constructed from low-grade plastic that will quickly deteriorate. Look for a well-built station, and stay from “all-in-one” units where all the sensors are in a single housing. The sensors represent the bulk of the cost, and if one fails, you’ll need to replace all of them—even if the others are working just fine.
A word about sensor placement
Now here’s where my meteorologist side comes out. Please, please, please choose carefully where you place your instruments. The temperature and humidity gauge should be placed in an shaded and grassy area about eye-level height off the ground (National Weather Service specifications say five feet), and out of direct rain or snowfall. Do not place it near or above concrete, macadam, or other potential heat radiators. This means your bedroom window, too: warm air escaping from your house will throw off its readings.
For the rain gauge, the level you place it at isn’t as important. What is important is that it’s not placed too low, so that splash-back from the ground causes abnormally high readings, or near tall obstructions that might block rainfall in windy conditions. The NWS generally recommends you place the rain gauge as far from obstructions as they are high. That’s tough to do, so just put it in as clear of a spot as possible.
The anemometer (the fancy name for the wind gauge) is the toughest instrument to place. Most people are surprised to find out that the wind speed readings you see on TV are taken at a height of 33 feet above the ground. That’s not practical for most of us, but try to get it 10 feet above any nearby obstructions if you can. You'll also need a compass nearby: you’ll need it to point the wind vane in the right direction. The station’s setup instructions will tell you how to align it correctly.
