Dosing system and method for dispensing at least one chemical composition inside the tank of a toilet

A dosing system for dispensing at least one chemical composition into a tank of a toilet, the dosing system comprising:

• at least one sensor configured to obtain a parameter representative of a current state of an environment of the toilet;
• a non-transitory control unit capable of receiving the measured parameter and configured to generate at least one activation signal for triggering dispensing of an amount of the at least one chemical composition into the tank of the toilet based at least in part on the parameter;
• a dosing device configured to be inserted inside the tank of the toilet, the dosing device comprising:
• at least one cavity containing the at least one chemical composition,
• a dispensing mechanism coupled with the at least one cavity, the dispensing mechanism being configured to receive the at least one activation signal from the non-transitory control unit and to dispense the amount of the at least one chemical composition into the tank of the toilet upon reception of the at least one activation signal,
• wherein the non-transitory control unit is configured to exchange data with a mobile device, data received from the mobile device providing the non-transitory control unit with a program comprising a set of rules associating values of the parameter representative of the current state of the environment of the toilet with properties of activation signals for triggering and setting the duration of dispensing of amounts of the at least one chemical composition into the tank of the toilet.
