The Things.io platform helps developers manage dependencies, interoperability worries, and libraries for connected IoT devices, providing monitoring reports and data analytics. The platform allows users to set up SMS alerts for temperature monitoring, triggering an alert if the device gets too hot, enabling immediate action to be taken to address the issue. To implement this functionality, a developer must create a trigger in the Cloud Code feature of The Things.io, specifying the JavaScript code that will be executed when an event occurs, such as writing data to a thing. In this example, the script sends an SMS with a message indicating the device is too hot and provides instructions on how to take action.
