1. A method of associating a hygiene monitoring device to a station device, the hygiene monitoring device being configured to monitor a hygienic state of a user, the method comprising:
coupling the hygiene monitoring device to a user located at a defined spatial region which is in proximity of the station device, the hygiene monitoring device configured to monitor a hygienic state of the user and configured to transmit hygienic information indicative of the hygienic state of the user;
the hygiene monitoring device obtaining, when in use, a station identifier (SID) from the station device located at the defined spatial region along with the user;
the hygiene monitoring device at least one of storing the station identifier and transmitting the stored station identifier along with the hygienic information;
receiving, by a receiving entity, the station identifier and the hygienic information from the hygiene monitoring device;
determining, by the receiving entity, a spatial location corresponding to the station device based on the received station identifier, and the hygienic state of the user based on the hygienic information;
in response to detecting a change in the hygienic state of the user based on the received hygienic information, transmitting a notification information from the receiving entity, the notification information including an alert of the change in the hygienic state of the user and the station identifier indicative of the spatial region at which the station device and the hygiene monitoring device coupled to the user are both located,
wherein the hygiene monitoring device obtains the station identifier when placed within the defined spatial region in the proximity of the station device so as to provide an association between the hygiene monitoring device and the user with which the defined spatial region is associated, and
wherein the hygiene monitoring device is removably attachable to a disposable absorbent hygiene article wearable by the user, and monitors a hygienic state of the disposable absorbent hygiene article, the hygienic state including a soiling event.
