If the Mijia Air Conditioner Eco EGAT Label No.5 with 1 Star 18000BTU fails to connect to the Xiaomi Home App, please refer to the following steps to troubleshoot:
1. Check if the air conditioner is powered on and in pairing mode. Unplug the device for 10 seconds, then plug it back in, or reset the Wi-Fi settings before reconnecting.
2. Please check if the connected Wi-Fi is a 2.4 GHz network. The air conditioner only supports 2.4 GHz Wi-Fi and does not support 5 GHz Wi-Fi.
3. Ensure that the router is within a reasonable distance from the air conditioner and that it is functioning properly.
4. Make sure the router's SSID and password do not contain Chinese characters or special symbols, and verify that the entered SSID and password are correct.
5. Set the App region to your current location.
6. Try connecting using a mobile hotspot to check if the issue is with the router network.
7. Update the Xiaomi Home App to the latest version or uninstall and reinstall it. Make sure to follow the step-by-step instructions in the Xiaomi Home App to connect the air conditioner.
8. If the problem persists, please contact the after-sales service center for further inspection.
