Abstract: An aerosol-generating device is provided, including: a cavity configured to receive an aerosol-forming substrate; an electrical heater to heat the substrate when received within the cavity; a power supply; and a controller to control a supply of power to the heater during a first time period and a subsequent second time period, determine an initial temperature of the heater, and to determine a rate of increase in temperature of the heater during the first time period by determining a time taken for a temperature of the heater to increase from a first to a second predetermined temperature during the first time period, and adjust the supply of power to the heater during the second time period based on the initial temperature of the heater and based on the determined rate of increase in temperature of the heater during the first time period.

Abstract: Aerosol-generating apparatus (100) for self-diagnosis allow users to initiate the self-diagnostics and then provide a diagnostic indication using, for example, indicators (162). The aerosol-generating apparatus (100) may include an aerosol-generating device (102) and a host device (101). The host device (101) may include one or more user-selectable switches (152) to initiate a self-diagnostic procedure and one or more indicators (162) to depict or display the diagnostic indication.
