What to do if all devices appear offline in the Mi Home/Xiaomi Home APP?
For your reference, you can refer to the following methods:
1. Check if the Mi Home/Xiaomi Home APP version is the latest. Please use the official online version;
2. Check if there is an issue with the router’s external network connection;
3. Try changing the router’s channel;
4. Most Xiaomi smart devices only support 2.4GHz Wi-Fi and do not support 5GHz Wi-Fi. If your home Wi-Fi environment is 5GHz or a combined dual-band Wi-Fi, the device will fail to connect or experience instability;
5. Routers can support a maximum of 128 devices on 2.4GHz + 5GHz. If there are too many devices at home, it is recommended to use a Xiaomi-supported mesh network router to improve Wi-Fi stability;
6. Xiaomi smart devices do not support Wi-Fi names or passwords with special characters or full Chinese characters. If the Wi-Fi name or password involves special characters or Chinese characters, the device will fail to connect or experience disconnections;
7. For issues with Zigbee or Bluetooth/Bluetooth Mesh devices frequently disconnecting, check the number and distribution of gateways in your home. If there are many smart devices, the signal from the gateway can be interfered with. If there are walls or if the home is large or has multiple floors, it is recommended to add more gateways to increase signal strength for better device stability;
8. Confirm the actual distance between the device and the router. If the device is too close to the router, interference will cause poor signal quality. Try to avoid placing them too close together;
9. Uninstall and reinstall the Mi Home/Xiaomi Home APP;
10. Restart the router by disconnecting the power.
If your device is offline, however, the Wi-Fi strength and other information appear good, it is because the network information was reported by the device before it went offline (including Wi-Fi name, Wi-Fi strength, RSSI, and packet loss rate).
Note:
1. RSSI: Received Signal Strength Indication is used to determine the link quality and whether to increase the broadcast transmission strength. An RSSI value of -50 or within is considered good, while higher values indicate poorer signal quality;
2. Packet loss rate: The packet loss rate is the number of data packets received over a period divided by the total number of data packets sent. It is the ratio of packets received to packets sent. Subtracting this ratio from 1 gives the packet loss rate. Since some data packets can be sent but not received (i.e., lost), there is a probability that packet loss will occur. A packet loss rate of 0% indicates smooth network communication. Therefore, the lower this value, the better.
