Want to learn more about how to use Valarm Tools Cloud APIs for your groups of remote sensor devices?
In this 2 minute video tutorial you’ll see how easy and cost-effective it is to use Device Groups for remote telemetry and environmental monitoring with Valarm sensor solutions. This step-by-step instructional video covers JSON, KML, CSV, and GeoRSS APIs that you can use to serve up your real-time sensor data to any endpoint of your choice.

Hello, this is Edward from Valarm. In this video you’ll learn how to use Valarm’s APIs for device groups with Valarm Tools Cloud. After you’ve logged in to your tools.valarm.net account go to the Device Manager page. If you haven’t already created a device group then make one by clicking the create a new device group button under Device Groups in the upper left. Be sure you’ve got Valarm devices associated with the device group you want to share via APIs. Now select your device group in the drop-down list, then click the “edit this device group” button. You can easily turn on Valarm APIs by clicking the checkbox to enable REST endpoints. Click save and then you can use the Valarm API URL generator by clicking the blue icon under Device Groups. Note that this is just an API URL generator to help you automatically create URLs, but you can manually create and edit the URLs and parameters as you need. You can use the query API to get Valarm data from a specific time period or the latest API to get the most recent Valarm device data.
There are 4 APIs you can choose from in the drop-down menu: JSON, CSV, KML, and GeoRSS. Here I’ll get the latest alerts in GeoRSS format. Now all you need to do is copy and paste the URL to your destination where you want the real-time Valarm sensor data. Here’s what the GeoRSS output looks like in a web browser, you can see there’s water flow rate data here from a water monitoring setup, radioactive particle data from a radiation monitor or geiger counter, as well as particulate matter (PM2.5) and air quality data from another Valarm device. All of the most recent sensor data from your device group is returned each time you access the API URL.
Here’s an example showing how easy it is to add real-time data in ArcGIS online. On arcgis.com I’ll make a new map then click add layer from web and paste in my the Valarm GeoRSS URL I copied to the clipboard earlier. Now we’ve got all of the geotagged, time-stamped sensor data on a map and can see exactly where and when the air quality and radiation sensor data occurred.
