Abstract: An example method comprises receiving, at a server system, a data message sent from a receptacle device via a network, the data message including: a receptacle identifier that uniquely identifies the receptacle device from one or more receptacle devices connected to the server via the network, and sensor data comprising a weight of a consumable disposed within or on the receptacle device, retrieving, by the server based upon the receptacle identifier, a consumable type of the consumable, retrieving, by the server based on the consumable type or the receptacle identifier, a predetermined consumable rule, comparing, by the server, the weight of the consumable with a threshold weight defined in the predetermined consumable rule, and providing an alert, by the server in response to the comparison, to a remote user device.
