If the Mijia Air Conditioner Pro Eco 5-Star 1.5 HP Inverter cannot connect to the APP, please refer to the following steps to troubleshoot:
1. Check if the air conditioner is turned on and in connection status. Turn it on again after 10 seconds of power off, or reset the air conditioner’s Wi-Fi and try reconnecting again;
2. Ensure that the connected Wi-Fi is a 2.4GHz network, as the air conditioner only supports 2.4GHz Wi-Fi and does not support 5GHz Wi-Fi;
3. Ensure the router is not too far from the air conditioner and that the router is functioning properly with internet access;
4. Make sure the router’s SSID and password do not contain Chinese characters or special symbols, and verify that the SSID and password are entered correctly;
5. Try manually setting up a mobile hotspot to see if the issue is related to the router's network;
6. Update the Xiaomi Home/Mi Home APP to the latest version, or uninstall and reinstall the Xiaomi Home/Mi Home APP, and follow the step-by-step instructions in the APP to connect the air conditioner.
If the issue persists after following these steps, please request the after-sales service center for further inspection.
