In order to simulate peak values, tap the 3rd button on the card for that sensor. The application will ask if you wish to start simulating peak values. Select **Simulate** to begin. If the phone is connected to Cumulocity, then it will send these values to the platform instead of the measurements coming from the selected sensor.

Sending alarms and events requires the phone to be connected to Cumulocity. If the device is not connected, the icons are greyed out. Tap the bell icon to send an alarm.

This will open a dialog in which you can select the alarm text, its type, and its severity. Tap **Create** to generate the alarm and send it to the Cumulocity platform.

To generate an event, tap the 2nd button on the card for that sensor.
