Power Cut Failure/Wire Cut Theft Alarm Notification on Mobile IoT Device(wifi router must have power backup to receive notifications on phone)

The device gives power cut alarm of 120db sound as well as notification on your mobile android app. Very easy to install. Device requires 2x1.5v cells and 9v battery. For anti-theft measure, you have to specify to customise your order.
PLS NOTE: IF ALARM SOUND IS FEEBLE/LESS, PLS REPLACE THE BATTERY BECAUSE IT HAS DRAINED
1. Plug-in the adapter of the device in any power socket and ensure that device is getting electric supply from the socket.
2. Put a 9v battery in the battery compartment of the device.
3. Now, if electricity supply is present, the device will not ring an alarm. But, if the power supply goes away, the alarm should sound from the device. You can test/simulate this by removing the adapter of the device from the socket(to simulate power supply cut off). It has 10 second auto shut off option. Pls use Tuya or Smart Life3 app from appstore to pair the device with router. The wifi router must have power backup for you to get notifications on your mobile as that uses internet to send you notifications.
