I’ve been attempting to get my arms on a WeatherFlow Tempest for years. After I first noticed the gadget on Indiegogo in late 2016 (that’s not a typo), it seemed like nothing else obtainable on the time. Now that it’s lastly right here, there’s nonetheless nothing higher. Different climate stations are complicated, difficult to put in, and contain massive sensor suites. The Tempest homes every thing in a single impossibly small and easy-to-set-up enclosure.
The Tempest took for much longer than anticipated to succeed in the market. WeatherFlow promised backers a station by 2017, however manufacturing points and delays repeatedly pushed its launch again. Many of the unique backers didn’t get their stations till 2018 or later. And whereas the corporate was taking preorders—most of these preorders didn’t make it into prospects’ arms till this 12 months.
What took so lengthy? It was what was inside. Whereas the Tempest has all the required measurements, similar to temperature, humidity, wind, and rainfall, the devices taking these measurements are housed in a single package deal that isn’t a lot bigger than your hand—it’s tiny by climate station requirements. The Tempest additionally measures wind and rain in a different way than simply about another station in the marketplace.
This assessment is a part of TechHive’s protection of the best home weather stations, the place you will discover evaluations of competing merchandise, plus a purchaser’s information to the options it’s best to take into account when buying.
Whereas wind pace is measured sonically—a way that Netatmo’s Smart Anemometer launched to the patron climate station market 4 years in the past—WeatherFlow’s haptic rain sensor is one thing I’ve by no means seen earlier than.
As an alternative of utilizing a tipping-bucket mechanism, a typical technique for dwelling climate stations for greater than twenty years, the Tempest measures rainfall by sensing raindrops placing the Tempest’s prime. WeatherFlow has a patent on this technology.
From what I can collect, that new expertise was a lot of the holdup: It takes time to get issues proper. However boy, did they. This climate station is a game-changer, and at $329, whereas not the most affordable, the Tempest is the most effective station I’ve examined.
There isn’t a lot to do in relation to setup. Your complete sensor suite comes preassembled, and at 7.25 inches in diameter, 12 inches in size, and weighing simply three.5 kilos, it’s surprisingly small and light-weight. For set up, you possibly can connect it to the highest of a mast (the strategy I used) or screw it onto the highest of absolutely anything utilizing its customary tripod mount.
The package deal additionally features a Wi-Fi base station, which the Tempest makes use of to hook up with your property community. Your complete setup course of is inside the app, and I had the station up and reporting information in simply 5 minutes.
Even sensor set up was a breeze. I hooked up the included mast mount to the sensor suite, hooked up that to the highest of the pole, tightened the mount as instructed, and had it exterior in simply 10 minutes. That’s the quickest set up of any station I’ve examined—by a big margin. With some stations, it takes as much as 30 minutes to totally set up every thing.
In contrast to many climate stations, the Tempest doesn’t have a console, so that you don’t get the standard indoor measurements that you just get with different dwelling climate stations. (I don’t assume that’s a problem as you have purchased a climate station to comply with the climate outdoor anyway.) The smartphone and web-based apps act as your console, repeatedly updating as soon as each three seconds or so (you can see my data here).
However you get each climate variable you’d want and extra. Temperature, humidity, wind pace and course, and rainfall are all coated. The station additionally has a built-in lightning detector and a UV and light-weight sensor that experiences the UV index, brightness, and photo voltaic radiation, too.
And such as you’d anticipate for a “good” climate station, there are Alexa and Google Assistant integrations and the potential to attach and set off good dwelling gadgets via IFTTT.
However its finest characteristic isn’t essentially seen to you, at the least not initially. As soon as your station is up and reporting, your information is integrated into WeatherFlow’s community to provide higher forecasts. That is fairly cool.
An ideal consumer expertise
The short set up of the Tempest begins every thing off on the fitting foot. However poor consumer expertise can break every thing, and over time, I’ve run into my share of quirks and frustrations with numerous climate stations.
The Tempest has none of those. The app is easy and simple to make use of, and every thing works. Information had been obtainable within the app and thru the web-based portal nearly instantly, with no calibration. WeatherFlow tells me that the Tempest calibrates itself, and also you should not have to mess with any sensor settings.
From watching the info roll in, it seems that observations are taken each 2 to 30 seconds, relying on the sensor. WeatherFlow did not have any specifics obtainable as they nonetheless had been writing the specs and consumer manuals on the time of our take a look at. We’ll replace this assessment when remaining specs are launched.
I couldn’t spot any inconsistencies within the information from the management information I used, which is a close-by Nationwide Climate Service observing station. Even the wind information, which is usually inaccurate resulting from siting issues with home weather stations, was inside acceptable limits and nearer to precise wind speeds than different stations, even with a sub-optimal set up location. I walked away impressed with the standard of information it put out, and the way properly every of its sensors carried out.
Tremendous-sensitive, correct instrumentation
The Tempest sensors look like of top quality. The haptic rain sensor was my greatest concern previous to testing, as a result of the expertise behind haptic rain detection is model new and vexed WeatherFlow engineers early on.
I’m completely satisfied to report that my fear was unfounded. The haptic rain sensor works and it really works properly. The sensor did have detection points in conditions the place there was very mild drizzle or very mild rain. As a rule, nevertheless, it was fast to detect precipitation.
There was a passing rain bathe early on in my take a look at, and I used to be stunned to obtain an alert that rain was falling—as a result of it didn’t look prefer it was raining. However certain sufficient, there have been a couple of drops on the bottom. That is nice for good dwelling customers—as a result of all the opposite detection mechanisms I’ve seen depend on a tipping bucket. In a light-weight bathe, it would take some time for sufficient rain to tip the bucket. The Tempest detected rain inside seconds.
Not solely that, WeatherFlow’s haptic rain sensor can even measure the depth of rainfall. I can solely surprise if it might be upgraded down the street to detect precipitation kinds as properly. That, nevertheless, includes expensive and sophisticated expertise. Regardless of the case, I discovered rainfall measurements typically correct (additional testing is required right here to make a full willpower), so WeatherFlow’s new technique of rainfall measurement will get a thumbs up from me in the meanwhile.
The UV and light-weight sensors additionally appear to work significantly better than another dwelling climate station I’ve examined. I’ve observed an inclination in my checks the place UV and light-weight readings appear to drop off precipitously after the solar passes under the rooflines of the homes to the fitting of the place I place the stations. I didn’t see the identical form of drop off with this gadget, the measurements seemed extra pure. That’s an necessary consideration for good dwelling integrations, since inaccurate mild readings can set off your lights to return on too early. I’ll chalk this success as much as the Tempest having a lot greater high quality mild sensors than different climate stations I’ve examined.
Excellent lightning detection
Temperature, humidity, and stress readings all fell inside acceptable ranges, that means they had been as correct as the most effective stations on the market. And in contrast to the AcuRite Atlas, the lightning detector isn’t suffering from false strikes.
I used to be lucky to have a line of thunderstorms move via twice throughout my assessment. The efficiency of the detector was excellent. Over three hours, the Tempest detected almost 2,800 strikes with the primary line, the furthest 28 miles away. I’ve solely examined lightning detection with the Atlas, which wasn’t that station’s sturdy level. Its lightning detector recorded only a quarter of that quantity.
From what I may collect, that 2,800 strike quantity was fairly near the precise variety of strikes that occurred, wanting via lightning information. I additionally acquired alerts as strikes bought nearer, and when new strikes occurred after prolonged intervals of no detection.
The way in which the Tempest app graphically shows lightning information is completely different from different strategies. As an alternative of cumulative strikes or strikes per minute, it reveals the strikes utilizing time because the horizontal axis and distance because the vertical. What this lets you do is best decide the place the strike is coming from. Because the storms get nearer, you start to see patterns within the information.
That’s the storm approaching us, after which dissipating because it strikes away. Graphs of cumulative strikes are additionally obtainable, however you’ll have to faucet on the “final three hours” depend on the station information display screen within the app to view.
Nice for good dwelling fans
Seeing as you’re studying this assessment on TechHive, there’s an excellent likelihood you’re a wise dwelling fanatic. Many climate stations have began including good dwelling capabilities, however the Tempest is finest in school, though all of those options received’t be obtainable till Tempest’s official launch in July.
The Tempest helps each Alexa and Google Assistant, and the experiences given are informative and, most significantly, succinct. Different implementations appear to overload you with data. For instance, Ambient Climate’s take nearly 30 seconds to complete. Whereas WeatherFlow’s report isn’t as detailed, you get all the knowledge you want in a 3rd of the time.
WeatherFlow additionally permits you to connect with IFTTT, permitting climate occasions to set off different good dwelling gadgets. The connectivity works properly and permits you to set triggers for any of the station’s sensors. There’s even a set off for every time the station takes an commentary, permitting you to repeat your observations to a Google spreadsheet, for instance.
WeatherFlow took so lengthy to carry the Tempest to market that it feels just like the second era of good dwelling climate stations. Netatmo paved the best way early on, and different firms raced to catch up, however WeatherFlow beats all of them.
The corporate made the fitting transfer, although; the Tempest feels, performs, and appears like a contemporary climate station. Its internals are higher, and its sensors are a lot higher than the competitors. And it’s constructed by an organization that has been making commercial-grade weather stations for greater than twenty years.
If I needed to nitpick, the truth that there’s no method you possibly can develop the Tempest proper now’s one in every of its few negatives, in addition to the worth: $329 is on the upper finish for certain.
When you want expandability, I wouldn’t blame you for choosing the less-expensive Ambient Weather WS-2902B, as an alternative. It’s an acceptably correct climate station with good good dwelling integration. However the Tempest is the long run in dwelling climate stations, and it’s well worth the greater price ticket for those who’re severe about accuracy and efficiency.
