自宅WiFi監視

◆Purpose and Overview
This app aims to reduce the amount of data consumed when watching videos or using other data while mistakenly believing you're automatically connected to Wi-Fi at home.
It displays a warning notification when the device switches from Wi-Fi to a mobile network within your registered home network area.
Instead of constantly acquiring location information, it only briefly checks your location when the network switches to determine if you're at home, thus minimizing device overheating and battery consumption.

◆Setup Procedure
1. Access to Location Information: Select "Precise Location" or "Only when using the app"
2. Send Notifications: Allow
3. Settings - Home Location Settings: Press "Register current location as home" near the center of your home
4. Settings - Detection Radius: Set the radius from your home location to determine if you are outside your home
5. Settings - Permissions: To monitor even when using other apps, press "Open background location permission settings" and select "Always allow" in the displayed location permission settings
6. Return to Status and press "Start Monitoring"
7. After a while, if "Home WiFi Monitoring" appears in the notification list, it is successful.
8. From now on, monitoring will continue in the background even when using other apps.

◆Monitoring Operation Confirmation Method
1. Set the detection radius to a distance where WiFi is temporarily out of range (e.g., 100m)
2. Leave this app in the background
3. Actually move from your home to a location outside of WiFi range
4. If an alarm notification is issued, it is successful.
5. Return the detection radius to its original value.

◆Mechanism: When switching from a WiFi connection to a mobile connection, the app briefly checks if your current location is within the home range using GPS. This app will send an alert notification when you are using a mobile data connection at home. Similarly, when you switch from a mobile data connection to a Wi-Fi connection, it will check your location to determine if you are still at home, dismiss the alarm, and continue monitoring.

Notifications cannot be sent if you do not have permission to always send alerts or if they are set to silent.

◆Notes
・Depending on your device's location settings, notification settings, and power saving settings, notifications may be delayed or not displayed.
・Depending on the indoor environment or device environment, it may not be possible to acquire location information in a short time.
・If notifications are muted or notification permission is not granted, you may not notice the warning.
・This app does not completely prevent data usage. It is an auxiliary app to make it easier to notice Wi-Fi switching.
