Tobacco industry product and methods relating to tobacco industry products

A method of determining a condition of a connection interface of a tobacco industry product, the method comprising:

• monitoring a temperature sensitive element placed in thermal contact with a connection interface;
• determining a number of times the operation of the connection interface is inhibited due to an increase in temperature of the connection interface, based on the monitoring of the temperature sensitive element;
• and
• determining whether the connection interface is in a first condition or a second condition on the basis of the determined number of times the operation of the connection interface is inhibited,
• wherein the first condition indicates normal functioning of the connection interface and the second condition indicates a fault condition of the connection interface.

The method of manufacturing an apparatus for heating aerosolizable material to volatilize at least one component of the aerosolizable material, the method comprising:

• providing a temperature sensitive element adjacent a connection interface of the apparatus such that the temperature sensitive element is in thermal contact with the connection interface;
• providing a controller configured to:
• monitoring whether the temperature sensitive element is in a first state or a second state, the first state being a state of the temperature sensitive element responsive to a temperature below a temperature threshold and the second state being a state of the temperature sensitive element responsive to a temperature above the temperature threshold;
• and
• determining a fault condition of the connection interface based on a history of the state of the temperature sensitive element.

A tobacco industry product comprising:

• a charging port for supplying power to the tobacco industry product;
• and
• a temperature detector positioned in thermal contact with the charging port such that heat is exchanged between the temperature detector and the charging port,
• wherein:
• operation of the charging port is inhibited responsive to the temperature detector detecting that the temperature of the charging port is above a temperature threshold.
