Abstract
An apparatus includes a temperature sensor, a pressure sensor, a communication interface, and a hardware controller. The hardware controller may detect a door open and close event for a refrigeration unit and receives temperature readings from the temperature sensor and pressure readings from the pressure sensor. The hardware controller determines whether a performance level of the seal has fallen below a threshold level based on the temperature and pressure readings and transmits a signal through the communication interface responsive to a determination that the performance level of the seal has fallen below the threshold level.
