Emergency alerts on wireless networks Xiaomi: the principles of operation, configuration and nuances

Why Xiaomi is sending emergency notifications over Wi-Fi

Have you ever received a sudden notification on your Xiaomi smartphone with a loud signal, even though all alerts are turned off in the settings? or noticed how the Yeelight smart bulb starts flashing red for no apparent reason? Most likely, it triggered the system of emergency alerts over wireless networks — a little-known but critical feature of the Xiaomi ecosystem. It is designed to instantly transmit emergency warnings — from natural disasters to man-made accidents — directly over Wi-Fi or mobile networks, bypassing traditional communication channels.

Unlike standard push notifications, these alerts are not dependent on installed applications and can even come to devices with a dead battery or in power saving mode. The technology is integrated into MIUI firmware, Mi Router routers and smart gadgets of the brand, but most users do not know its existence until they encounter it in an emergency. In this article, we will discuss how the system works, which devices support it, and why it can not be completely turned off (even if you really want to).

How to use emergency alerts in the Xiaomi ecosystem

The technology is based on the Wireless Emergency Alerts protocol (WEA), Xiaomi is adapted for its devices, unlike the classic ones. SMS-alerts (as in system 112), wireless data transmission via:

• 📶 Mobile networks (3G/4G/5G) — smartphone-tablet;
• 📡 Wi-Fi networks – for smart devices (lamps, speakers, sensors);
• 🔄 Mesh networks – in the Mi Home ecosystem (alerts are transmitted from device to device).

Key feature: messages are encrypted and have maximum priority on the network, for example, if you have an evacuation in your area due to a fire, the alert will break through any traffic, whether it is a movie download or an online game.

• 🔋 On smartphones with MIUI The alert will wake the device even when the screen is off;
• 🔊 The sound signal cannot be turned off by standard means (volume is fixed);
• 🌍 Geolocation is determined by nearby towers or Wi-Fi points, not by GPS (battery-saving).

Important: Xiaomi cooperates with local emergency services, so the alerts depend on the region, for example, in Japan, it is a tsunami warning, in Europe, it is a terrorist threat, and in Russia, it is a man-made accident or weather disaster.

What Xiaomi devices support emergency alerts

The feature is not available on all of the brand's gadgets, and here's the full list of compatible devices (as of 2026):

⚠️ Note: On devices older than 2020 (such as the Redmi Note 9 or Mi 10), the feature may not work as well due to the outdated EmergencyBroadcastReceiver module. MIUI, activate support.

The smartwatch and fitness bracelets (Mi Band 7/8, Watch S3) don’t receive text alerts, but can vibrate or blink at emergency signals if synchronized with a smartphone via Mi Fitness.

How to turn on or off emergency alerts

By default, the function is activated on all supported devices, but it can be customized or partially limited.

📱 On smartphones and tablets (MIUI)

1. Go to Settings → Applications → Application Management;
2. Slip on three points in the upper right corner and select Show System;
3. Find emergency alerts (or emergency alerts)
4. Turn off sliders for unnecessary types of alerts (e.g., "Test Notices" or "Advertising Messages").

⚠️ Warning: You can't completely turn off government alerts (such as terrorist threats) -- this is prohibited by most laws -- and the most you can do is reduce the vibration or sound for non-critical notifications.

📡 On Mi Router routers

To manage the broadcast of alerts to connected devices:

1. Go to the router’s web interface at 192.168.31.1;
2. Go to Additional → System Tools → Emergency Notifications
3. Choose which types of alerts to broadcast: 🚨 Emergency situations (fires, floods); ⚠️ Warnings (severe frost, storm); 📢 Test messages (can be turned off).

💡 Smart lamps and speakers.

The settings are more modest here:

• In the Mi Home app, select the device → Settings → Notifications;
• Activate the option of Emergency signals;
• Then, set the color of the lamp to the red.

💡

If you travel frequently, add "Home Regions" to Mi Home for different countries, which will help you get local alerts without manually reconfiguring.

Why Warnings May Not Come (and How to Fix It)

If you are in an emergency area but have not received a notification, the problem may be one of the following:

Critical information: In some regions (e.g. China), alerts are tested monthly. If you see messages in Chinese marked with a "cèshì" ("test"), it is not a failure, but a routine check. You can turn off test notifications in the settings, as described above.

Another common mistake is using custom firmware (LineageOS, Pixel Experience), which often removes the EmergencyInfo system application responsible for alerts, in which case return to the official MIUI or install the XiaomiEU module with WEA support.

Security and privacy: What Xiaomi knows about your location

Many users fear that emergency alerts are used to collect geodata, and let's see how this actually works:

• 📍 Localization is determined by the nearest cell towers or Wi-Fi points, not by the nearest cell towers. GPS. Accuracy – about 500-1000 meters (enough to alert the emergency zone, but not enough for accurate tracking).
• 🔒 Data is not stored on Xiaomi servers for longer than 24 hours, and once you send an alert, your location information is erased.
• 🚫 No access to personal data: the alert system is separate from Mi Account and is not linked to your contacts, photos or browser history.

However, MIUI has a hidden setting to limit the transmission of geodata for alerts:

1. Activate Developer Mode (7 times tap the MIUI version in your phone settings);
2. Go to Settings → Additional → For developers;
3. Find the option to Limit background geolocation and add emergency alerts to the exceptions.

⚠️ Warning: Disabling geolocation for alerts may result in you not receiving critical notifications, such as if you are in a chemical accident area but your phone doesn't know where you are, the system won't be able to alert you.

💡

Xiaomi’s emergency alerts don’t use GPS for tracking, but without approximate geolocation (tower or Wi-Fi) you won’t receive local alerts.

Frequent Questions and Myths About Emergency Alerts

There's a lot of rumors going around this feature, and we're going to look at the most popular ones.

Conclusion: whether to trust the system of emergency alerts Xiaomi

Wireless emergency alert technology is not a marketing ploy, but a real-world security tool, which has already saved thousands of lives in Turkey’s earthquakes (2023), floods in Germany (2021) and wildfires in California (2020), and is integrated deeper into Xiaomi’s ecosystem than competitors, where not only smartphones but smart devices are alerted, increasing the chances of timely warning.

Of course, there are nuances: sometimes false positives come and setting up on older devices can be difficult, but the pros outweigh the cons — especially if you live in a high-risk region. Our advice is not to turn off alerts completely, but to customize them to your needs (for example, turn off test messages and leave only critical ones).

If you've read this, you now know more than 90 percent of Xiaomi users about the feature, which means you'll be ready to act faster and more efficiently in an emergency.
