What to do if the turn-on/off timer function of the Mijia Air Conditioner Pro Eco 3.5 kW does not work?

If the turn-on/off timer function of the Mijia Air Conditioner Pro Eco 3.5 kW does not work, please follow these steps:
1. First, check whether the device is properly connected to the internet. The turn-on/off timer function requires a stable network connection to operate;
2. If the device is online but the function still cannot be used, try restarting the air conditioner to see if the issue is resolved;
3. If restarting does not help, check whether the scheduled task was set through the Mi Home/Xiaomi Home APP plugin. If so, make sure the device’s memory chip has not been reset due to a power outage. If the timer was set using an automation scene in the Mi Home/Xiaomi Home APP, please note that it will not work if the device is offline, as the command must be sent from the server via the network.
