How accurate are the sensors?
We're all about good data....because let's face it, bad data is misleading. That's why we have spent considerable effort sourcing and testing high-quality sensors for every device we produce. Combined with innovative technologies like our proprietary sonic anemometer and haptic rain sensor, our devices are every bit as accurate as scientific weather stations that cost 3X the price. See our sensor specs further down this page.
Why do I need a weather station at my house?
You might not realize this, but most weather apps and even your evening news is based on public domain data -- primarily on weather stations installed long ago at regional airports. Having a reliable weather station at your house can help you save money on heating & air conditioning based on the true environmental dynamics of your house, tell you exactly what's happening in your backyard (not the nearest airport), and allow you to make automated decision with your smart home systems.
Yes. Both the AIR and the SKY are battery powered and communicate either via Bluetooth Low Energy (BLE) and/or WiFi. The typical range is up to 300ft (100m) depending on situation, and blockages like cement walls, and WiFi strength. You can also use a WiFi repeater or signal booster to extend the range.
Yes. Go ahead, bring the AIR to the soccer game and detect lightning before it get's to you. Or place the SKY on your boat or at the beach to measure wind, rain, and solar radiation. The device can communicate with your connected mobile device and communicate the data to the cloud for instant viewing online.
Do I need to download the app to use the WeatherFlow devices?
Yes, the WeatherFlow app is required to setup and configure the smart weather devices. The app also serves as your daily weather data viewer. Once set up, you can also view your data through our web app, as well as other integrated weather apps such as Weather Underground Personal Weather Station.
Is the WeatherFlow mobile app free?
Absolutely! Available on iOS or Android before the products ships.
Do I need to have the DISPLAY, or can I use my iPad?
You can use any connected device to view your weather data. iPad - yes. iPhone - yes. Android phone or tablet - yes. Some folks love having a dedicated weather display in their house....which is why we're creating the DISPLAY -- coming later in 2016.
Will the devices work with any Smartphone or tablet?
Most of them. WeatherFlow devices are compatible with all iOS and Android 4.3+ devices with Bluetooth Low Energy support for direct connection to the devices. If the device is connected to your home WiFi network, your data is pushed automatically to the cloud. Then anyone / any connected device can view the data via the WeatherFlow app or a variety of integrated weather and smart home apps.
Why did you separate a weather 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.
Will they work with Weather Underground?
Yes. You can publish your weather station data directly to Weather Underground. We'll walk you through the WU set up in our app.
When will the DISPLAY and BREATHE devices be available?
The WeatherFlow DISPLAY will be available in fall 2016 -- it's designed for the user who wants a totally dedicated display for their weather station. The BREATHE should also be available in fall 2016 and can be added to your network with the same WeatherFlow app.
What does the BREATHE device do?
BREATHE will measure total indoor air quality including VOCs, CO2, Dust particles, Humidity, and Temperature. It's designed to monitor the air inside your house and allow you to automatically trigger smart home actions such as: turn on air purifiers, open the windows, tune heating and cooling, ventilate bad air, etc.
What is the reporting interval of the Smart Weather Station?
Temporal resolution and reporting intervals for the various sensors are something that we are constantly optimizing for both performance and efficiency. The 3 observations most critical to frequent update are: wind, rain, and lightning.
Temp, humidity, UV, and pressure do not fluctuate that much on a second-to-second basis to warrant.
We currently have three types of "reports": (1) regular, averaged reports (aka observations) that we take every 1, 5 or 10 minutes and (2) regular, instantaneous once per second updates (currently only from the wind sensor) and (3) irregular events that we report when they happen (currently lightning strike, onsite of rain, cessation of rain)
Only the first type of report is stored for long term download or viewing in a graph, table, etc. We have budgeted to store over a half million data points per station at the 1 min interval.
The second and third types are used for real-time display in the app. And the third type can also be used to trigger an alert (push notification).
