Abstract: A refilling device for an article of an aerosol provision system includes refilling control circuitry. The refilling control circuitry is configured to facilitate the transfer of aerosol-generating material from a reservoir to the article when the article is coupled to the refilling device. The refilling control circuitry causes a value of a counter stored on the reservoir to be updated in response to the transfer of the aerosol-generating material. The value of the counter is indicative of the amount of an aerosol generating material in the reservoir.
