What to do if the timer function on the Mijia Air Conditioner Pro Eco Inverter 1.5 HP is not working?

If the timer function of the Mijia Air Conditioner Pro Eco Inverter 1.5 HP is not working, please troubleshoot as follows:
1. First, check if your device is connected to the network properly, as the timer function requires a stable internet connection;
2. If the device is connected but the timer function still doesn't work, try restarting the device to see if that resolves the issue;
3. If the issue persists after restarting the device, check if you have set the timer function via the Xiaomi Home App plugin. Ensure that the device's storage chip has not been reset due to power loss. If the device is configured through smart scene to use the timer, it will not work after a network disconnection, as the servers need to send commands to the device over the network.
