Abstract: This invention further relates to a networking smart tray made of a tray configured to receive an object a sensor positioned to detect the presence of the object within the receptacle; a user interface in communication with the networking microcontroller; and a networking microcontroller configured to receive a sensor input and transmit a command to a smart device through a network connection. This invention further relates to a method to indicate if an object is absent from a networking smart tray, wherein the indication is shown in a selected smart device in communication with the smart tray. This method involves the steps of: providing the networking smart tray as described above, placing the object within or on the smart tray; and removing the object from the smart tray to generate a wireless signal to a selected smart device.
