Non-invasive attachable smart device housing and smart device methods and systems for beverage containers

A smart device for a beverage vessel comprising a domed surface at a distal end, the domed surface adjacent a wall terminating at a lip, the smart device comprising:

• a housing;
• and
• at least one lockable and unlockable expanding member, the at least one lockable expanding member being one of integral to the housing, attached to the housing, or separate from the housing,
• the at least one lockable expanding member configured to be locked in a deployed state so that the smart device will attach to the beverage vessel enabling a locking fit between the lip and the domed surface of the beverage vessel.

A smart device for a beverage vessel comprising a domed surface at a distal end, the domed surface adjacent a wall terminating at a lip, the smart device comprising:

• a housing;
• and
• at least one expanding member, the at least one expanding member being one of integral to the housing, attached to the housing, or separate from the housing and configured to be removed,
• wherein the at least one expanding member is configured to enable a dimension change from an initial vertical dimension to a greater locking fit dimension, the dimension change to provide a secure fit between the lip and the domed surface of the beverage vessel to the housing of the smart device.
