HWg-Trigger is a Windows software utility that alerts to a failed device (out of 10 listed), starts applications, or redirects alarms to text messages (SMS). An action (e.g. displaying a pop-up message) can be assigned to each condition (e.g. a sensor reading out of safe range).

HWg-Trigger is an alert management software for Windows (If-Than). An event is when sensor is disconnected, values out of allowed range, or pressed buttons. A condition triggers an action. For example, a text message (SMS) is sent to several numbers, a relay output is activated over the network, a Windows application is started, or a warning message is displayed.

A “Condition” (event) and its assigned “Action” form a “Rule.” Up to 90 rules can be added to the application. For each rule, a repetition interval can be specified. Each rule can be tied to an IP address (e.g. to distinguish if the notebook with the application is connected “at home,” “in the office,” or at a “public place”).
