transmitting a signal to a pump of an air mattress to set the pressure of the air mattress to an initial pressure;
receiving, at a central controller, a user preference condition for an automatic adjustment of the pressure in the air mattress;
receiving, at the central controller, an indication that the air mattress is empty; and
based on determining, at the central controller, that the user preference condition has been met and receiving the indication:
detecting a change in the pressure of the air mattress beyond a threshold value; and
based on the detection, transmitting an adjustment signal to the pump of the air mattress to energize the pump to adjust the pressure of the air mattress to the initial pressure.
