The schedule feature on Tapo Plug can still function without Internet or WiFi connection. However, if there is any power failure, it could potentially result in issues where the schedule does not activate on time or doesn't work at all.

If there has been a power outage, please reconnect the Tapo device to the internet to synchronize the correct time. Before disconnecting the network or Wi-Fi connection again, test the schedule functionality to ensure it is working properly.
