Yes, you absolutely can use a smart plug to turn a toy crane machine on and off. This simple method offers great convenience and control. First, ensure your toy crane is a plug-in model with a simple on/off switch that stays in the "On" position. Plug the crane's power adapter into the smart plug, and then plug the smart plug into your wall outlet. After configuring the smart plug with its companion app on your smartphone, you can power the crane on or off from anywhere with an internet connection. This setup allows you to create automated schedules, such as having the crane operate only during certain hours to save energy or for safety. It also adds a layer of safety by allowing you to ensure the toy is completely powered down when not in use, without needing to physically unplug it. Always check that the smart plug's power rating exceeds the crane's power requirements for safe operation.
