1. A controller comprising:
a memory; and
processing circuitry in communication with the memory, wherein the processing circuitry is configured to:
receive, from a leak sensor, a leak signal indicating a leak in a water tank of a water heater device;
activate, based on receiving the leak signal, an alarm device, wherein the alarm device is configured to receive power from a power source when the alarm device is activated, wherein the power source is configured to store an amount of energy;
control, based on receiving the leak signal, a main burner of the water heater device to occupy an extinguished state;
ignite, based on receiving the leak signal, an intermittent pilot light located proximal to a thermoelectric device;
cause the thermoelectric device to supply electrical energy to the power source, wherein the electrical energy increases the amount of energy stored by the power source; and
maintain the intermittent pilot light in the ignited state when the processing circuitry receives the leak signal.
