FAQ

What is an 'external station type'?

offers a variety of station types that collect data from third-party data sources and do not require any additional hardware to setup. We refer to these as 'external station types'. Note that because external station types are maintained by third parties, we cannot guarantee the frequency or quality of the data transmitted from these external data sources. External station types currently offered include GOES, Advanced Hydrologic Prediction Service (AHPS), US Geological Survey (USGS), Mesonet, SNOTEL and SCAN.

What is transmission health?

A station's transmission health is calculated by averaging each sensor's transmission history over the last 24 hours. If all sensors are reporting successfully then your station's transmission health will be 100%.

What is a Station Unique Identifier (SUI)?

The Station Unique Identifier (SUI) is an identification code which can be found on your Stevens data logging device. For external station types (e.g. USGS, AHPS, GOES) the SUI is used to identify the station code for the external weather station.

How do I update my alarm notification preferences

  • Update the notification settings for your account
    Navigate to your User Settings page by clicking the user menu in the top right corner of the page and selecting 'User Settings'. On the User Settings page you can update your alarm notification preferences by toggling 'Send alarms via email', 'Send alarms via SMS' or you can toggle both to receive notifications through both mediums. Be sure to click the 'Submit' button in order to save your changes.

  • Update the notifcation settings for an alarm
    If you want to stop or begin receiving notifications for a particular alarm, you can update this by navigating to your Project page and selecting 'Alarms' from the side menu. Click the alarm that you want to update the notification settings for and update the toggle next to your name.

Can I save or export the data produced from an Algebraic Function?

Algebraic functions can be used on their own to create tables and charts with the Trends feature. These charts and tables can be exported in multiple file formats including CSV, PNG, JPEG, PDF and SVG. Algebraic Functions can also be used in conjunction with a Virtual Sensor to allow the calculated data to be stored and tracked.

What is a virtual sensor and what can I use them for?

Virtual Sensors are designed to be used in conjunction with a predefined algebraic function or flow table. The purpose of a virtual sensor is to allow you to save the data from a physical sensor with a data transformation applied to it. A virtual sensor consists of virtual parameters and each parameter can be tied to a different algebraic function or flow table. Learn more about Virtual Sensors.

What's a Web Sensor?

A Web Sensor is a virtual sensor which pulls data from external data sources in the vicinity of your weather station. currently provides two types of web sensors: NOAA Daily Precipitation Total and Current Weather Conditions. You can use the web sensors to add an additional layer of data to your station. This data can be used in conjunction with your physical sensor's data to create charts and identify trends.

What's a published station and how can I publish my station?

allows any user to publish their own stations to the Station Directory. When a user publishes their station, the station's data will be made available to view by all users on the network. The Station Directory contains a list of all available published stations. You can search the directory and add any of the published stations to your favorites list. Once you favorite a station it becomes available when creating widgets or using Trends.

To publish your station, you must first make your project public by creating a 'Public Key' from the Project Administration page. Next, navigate to the Station Management page for the station you would like to publish and select 'Configuration' from the side menu. Edit the Station Visibility settings by setting 'Visibility' to 'Public' and 'Published' to 'Yes'. Your station will now be listed in the Station Directory which can be accessed from your Project page.
