For example, while in the bedroom, users can control devices in the living room, at the gate, or on the balcony, leaving more time for rest, relaxation, or work.<\/li>\n<li>Energy Saving: The product can help reduce unnecessary electricity consumption by allowing users to conveniently turn off devices when leaving the house or moving to another area.
