How do I change my station name?
You can change the name of your station any time via the settings in the app. From the main app screen, tap the setting icon in the upper left corner. Tap stations > select your station > then tap Name to rename as you wish. Make sure to hit SAVE button.
Can I see my weather station online?
Yes. Go to smartweather.weatherflow.com and user your WeatherFlow login credentials to view your station. You can also share your weather station with friends and family by sharing the URL noted at the bottom of your station’s web page. You can use any connected device to view your weather data. iPad – yes. iPhone – yes. Android phone or tablet – yes. Computer – yes. Anything with a browser.
Do I need WiFi?
Yes and no. Most people will locate their weather station at home and connect to a home WiFi network. Doing this will enable consistent weather data to flow into our servers and allow anytime data access. It is possible to operate a Smart Weather Station via your smartphone, however, data will only be reported when the phone is directly connected to the weather station (via BLE).
I don't have an iOS or Android device - how do I get through setup?
You can only set up your Hub through the iOS or Android applications. Although, some BlackBerry devices can run Android apps. If this isn't an option or if you have a Windows phone, try using a friend's or family member's iOS or Android device for the setup process. Once the Hub and devices are setup and configured to WiFi, you can access the data anywhere on the web.
What batteries should I use?
The HUB is designed to plug into a power outlet inside your house. We will supply a USB power cable for international compatibility. The AIR & SKY run on AA batteries. We strongly recommend using Energizer Ultimate Lithium (not alkaline, not rechargeable lithium ion) as they perform much better in variable temperatures. AIR uses four AAs, and SKY uses eight AAs. Both AIR and SKY are meticulously designed to consume a tiny amount of power allowing for super long battery life.
What is the wireless range of the devices?
AIR & SKY communicate with HUB via powerful sub-gHz telemetry radios and can maintain connection up to 300 meters (1000 ft+) unobstructed, in clear line of sight. The HUB should be placed no further from the router than any other wireless connected devices. Situations vary with obstructions, wall materials, signal interference and power.
Is there a solar radiation shield for the AIR?
If your AIR must be placed in direct sunlight - make sure to house the unit within an adequate solar radiation shield. There are solar shields available on the market, search “solar radiation shield”. We’ve tested the Ambient SRS100LX: http://a.co/fu9505i and the AIR fits snugly inside if you build the layers around the unit.
How frequently are measurements reported by the sensors?
All values are reported on a one-minute average cycle. AIR also reports instantaneous lightning events upon detection. SKY samples the wind every 3 seconds and sends an average of wind speed & direction to the Hub. SKY also reports instantaneous rain start events when more than 5 seconds of continuous rain occurs.
More on wind sampling...
Every 3 seconds the sonic transducers in SKY sample the wind speed and direction. These values are averaged in one-minute observations. The lull is the lowest of the 3-sec readings and the gust is the highest of the 3 sec readings. The one minute averages become part of your station’s long term record. These are World Meteorological Organization (WMO) standard sampling methods.
What does Power Save Mode do in SKY?
Power save mode saves battery power by reducing the wind sampling frequency of the sonic anemometers from 3 seconds (normal) to 15 seconds (power-save).
How is wind direction displayed?
Wind direction reports are based on where the wind is blowing from. Wind direction is displayed in degree format or cardinal direction. Conventional wind barbs point into the wind but in the Smart Weather app, the wind is treated as a vector - an arrow points with the direction of the flow.
How is pressure displayed?
The value displayed on the station home screen of the Smart Weather app is sea level pressure. Also known as relative pressure or barometric pressure, this is an adjusted value based on temperature and total height above sea level (elevation + height above ground).
Station pressure or atmospheric pressure is actually measured by the sensor. This value is not of much use to people, unless for some reason you want to know what the actual pressure is at your house (maybe for brewing beer or baking bread?). Station pressure is displayed in the list view in the app.
Pressure trends: A trend is determined from changes over 3 hour intervals.
If pressure fall ≥ 1 mb the trend is "falling"
If pressure rise ≥ 1 mb the trend is "rising"
If pressure change is ≤ 1 the trend is "steady"
How do you decide rain intensity values?
VERY LIGHT: < 0.25 mm/hour
LIGHT: ≥ 0.25, < 1.0 mm/hour
MODERATE: ≥ 1.0, < 4.0 mm/hour
HEAVY: ≥ 4.0, < 16.0 mm/hour
VERY HEAVY: ≥ 16.0, < 50 mm/hour
EXTREME: > 50.0 mm/hour
How do I view daily summaries of observations?
You can view daily summaries of observations at the outermost zoom level for any graphed parameter. The box plots represent the highest and lowest observed values for that day. The red line displayed in each box is the average value over the entire day, not the average of the highest and lowest value.
Will I lose data if my Hub/station experiences an outage?
AIR and SKY can store about 3 and 2 hours worth of data respectively and will continue pinging the Hub to reconnect. Once power to the Hub is reestablished and the devices reconnect, stored device data will be offloaded to the Hub for publication. Tip: In the event of a prolonged power outage, you can power the Hub with an external power bank.
AIR and SKY will continue transmitting data to the Hub. The Hub has can store about a week of data from one AIR and one SKY. Once internet connection is restored to the Hub, it will publish the data. Tip: The Hub is able to publish the data locally (UDP, BLE) as long as it has power (setup UDP broadcast and/or leave the app open on a Bluetooth connected device).
My humidity readings seem off, is something wrong?
The sensors inside the AIR are tested and calibrated no less than 3 times before they leave our factory. If you think your AIR is incorrectly reporting relative humidity, the first thing to do is check the immediate environment in which it’s located. The sensors are quite... sensitive and will pick up ambient moisture from ground vegetation, nearby trees, moisture in wood decks, dryer vents, etc. Siting differences will typically result in different data. Try moving your AIR to various locations and check the data, you might be surprised how each micro-climate differs.
Why is the lightning detector giving false positives?
The lightning detector in the AIR senses the small electromagnetic pulse produced by lightning. Although it will reject most non-lightning emissions, it may report so-called "false positives" from other electromagnetic sources including motors, microwave ovens, computer monitors, speakers, and even motion detectors. Be sure to locate the AIR away from such sources. Sometimes these sources are not obvious. If you experience false positives, the simple solution is to re-locate your AIR in a location free of electromagnetic interference. If however, you cannot identify any potential interference, or you are limited on siting options, subtle changes in the positioning of air can make all the difference. Try rotating your AIR so the logo or vent point toward another direction. If you live in a 'noisy' environment, you may want to disable the lightning alerts in the app or even disable the lightning sensor in the AIR altogether.
What is the RSSI value?
RSSI is a relative measurement of signal strength between either a device and the Hub or the Hub and your router/access point. The closer to zero the better the signal. For example, an RSS of -45 would be great. -12 is fantastic (AIR & hub are probably sitting right next to each other). -65 is still fine once you get close to -80 or -90, you're on the edge and could suffer from packet loss.
What does the 'Share Publicly' setting entail?
The 'Share Publicly' settings toggle allows you to decide whether or not others can view data from your weather station and also permits integrated services like IFTTT to use the data. This data does not include any personal identification. It does include a general proximity location for geographical context. If this is of concern, you can simply change the location of your station in the Station settings menu. Here's an example of publicly shared weather data: https://smartweather.weatherflow.com/share/3202
What are the IFTTT column headers for the observation log applet?
If you are using the pre-made applet, the column headers are as follows: Timestamp, AirTemp, Humidity, Pressure, LightningStrikeCount, HeatIndex, DewPoint, WetBulbTemperature, DeltaT, AirDensity.
Know that you can make new columns and convert from the base units or add a conversion to the data coming in to a cell. This is one of the pre-configured IFTTT applets which is simple to set up but the configuration cannot be changed. However, you can actually create your own applet with your own configuration (parameters, units, etc.).
To configure your own data logging applet...
From IFTTT, go to My Applets > New Applet > select WeatherFlow for the "If" part > choose New Observation. Then choose Google Sheets for the "Then" part > "Add Row" > customize your preferred ingredients to a formatted row.
How can I use my data on my website or blog?
There are several ways to integrate your smart weather station data into a website. If your website uses WordPress, check out the beautiful Weather Station plugin (https://weather.station.software/). You can also link your station to Weather Underground, then use one of their weather stickers (https://www.wunderground.com/stickers/). The desktop software Weather-Display (www.weather-display.com) is a powerful tool for visualizing weather data and also provides a nice way to publish data to a website. Finally, if you are an experienced developer (or know someone who is), you'll want to check out our API (https://weatherflow.github.io/SmartWeather/api/).

Full Smart Home Weather Station FAQs
Why did you separate the station into two devices?
Better siting, better data. In order to accurately measure wind, rain, and UV you need to place the SKY in an open area with a clear view of the sky above (like on your roof). As you can imagine, placing a temperature sensor in the full sun presents issues. That’s why we made the AIR a separate device to be placed in the shade — more accurate data.
How does the sonic anemometer work?
SKY houses a sonic anemometer in the top of the device. The SKY measures wind speed and direction based on the time of flight of sonic pulses between pairs of transducers. This allows for a high degree of accuracy especially in variable wind conditions. For more information see Wikipedia on Sonic Anemometers.
Does AIR really detect lightning?
Yup. Pretty cool, huh? The AIR actually detects cloud-to-ground AND cloud-to-cloud activity. Our sensor detects electrical transmissions from lightning activity up to 40km (approx. 25 miles) away and gives an estimate of distance. Humans can typically sense lightning only up to 25km away. The sensor algorithm is even smart enough to reject man-made signals such as microwave ovens and motors. That said, it’s important to place the AIR away from electrical disturbances for best performance. The maximum detection efficiency at 5km is about 40%, at 15km ~35%, and at 40km ~18% or so. Please note that the sensor is an early warning system designed to track the head of the storm, it is not necessary to capture every single lightning strike. It is enough to capture some events to get information on how far the leading edge of the storm is away from the sensor’s position. The system is based on statistical analyses of lightning strikes and is thus not comparable to expensive lightning measurement equipment.
How come I don't get an alert for every lightning strike?
To prevent users from being overwhelmed by lightning detection alerts, we set up a rule that our software follows: for each lightning strike, an alert is sent if it’s been more than 30 minutes since the last alert or if it’s closer than the previous strike.
How does the haptic rain sensor work?
SKY uses a patent-pending haptic rain sensor in the top of the device. Using a combination of pressure and capacitance, SKY measures and counts each falling raindrop. Algorithms exclude things that are not rain (like the rumblings of a passing train or Harley). This allows SKY to report the instant rain begins falling, the current intensity, and the total rain accumulation over time. Accuracy compares to a large tipping bucket, but does not get fouled with leaves or bird poop.
How durable are the AIR/SKY devices?
We use a marine-grade plastic formula for the device casings, which are designed to improve durability and keep the devices shining white for many years to come. No matter where you live; in the heat of Central Florida, bitter cold of Canada, or across the seas, the AIR/SKY won't degrade from years of weathering.
