You can enable “Arm/Disarm Notification” so that a push notification will be sent when the alarm mode is changed by one of your family members or friends with whom you share the system control with.
Tap on the hamburger icon in the top right corner of the WiFi Alarm page to open up the settings of your Chuango WiFi Alarm OV-300/LTE-400. Select “Advanced Settings” and enable “Arm/Disarm Notification”.
You could also activate the “Arm/Disarm Beep(s)” function. The hub will beep once the alarm mode has been changed.
If you have an extra wireless siren, such as the Chuango Mini Siren WS-105, you can consider activating “Arm/Disarm Beep(s)” under “Wireless Siren” so that the connected wireless siren will also beep upon mode change.
