If the chain is opened, you will get a vibration in your phone along with a notification. Chain when opened are separated, we will use this separation of the chain to understand if the bag is closed or open. A circuit is created so as, when the bag is closed the circuit is complete, and when the chain is opened the circuit breaks. When the circuit breaks, the ESP recognizes that the bag is opened and send a response to the mobile via an app. That Mobile apps also tracks the amount of charge is left in ESP, and also the history. The ESP is equipped with a kill switch, which can be toggled, when the module is not needed to be active.
