Why did you receive a text message from winglet housekeeper?

Binding with the intelligent door lock of Winglet Butler. The reason why I received the short message from Winglet Butler is because the number is bound to Winglet Butler's smart door lock. When setting the scene (paying attention to whether family members open the door or not within a specified time period), the number bound by the smart door lock of Winglet Butler will receive a short message from Winglet Butler.
