The customer is an international producer and bottler of beverages based in Central America. To increase sales and for advertising purposes, the branded refrigerators are made available to his customers free of charge within the framework of distribution partnerships.
The operation of these refrigerators posed two major challenges for the beverage manufacturer.
It had to be ensured that the refrigerators functioned perfectly at all times, as the beverage manufacturer complained of lost sales due to the faulty operation of its refrigerators. This includes both the optimal cooling of the beverages and the constant illumination of the brand advertising on the device itself. If problems occurred, the service teams had to be informed and dispatched as quickly as possible to prevent any adverse effects on beverage sales. In the past, however, since service staff had to travel to each individual sales partner location to inspect or repair the refrigerators, even in the case of mere suspicion of problems, this often resulted in high and avoidable costs in the past.
It was also necessary to ensure that the refrigerators were neither stolen nor misappropriated, for example by stocking them with products other than those of the drinks manufacturer, or by removing them from the points of sale to use them for purposes other than the intended cooling of drinks.
Together with an American system integrator and a world-leading manufacturer of IoT gateways, azeti developed a comprehensive solution for remote monitoring of beverage refrigerators for the customer. For this purpose, individual gateways were developed based on the project requirements. In addition to a large number of interfaces for connecting sensors, the gateway has a mobile radio modem and GPS for data communication, as well as a rechargeable battery which continues to supply the refrigerators and thus also the gateway with energy when there is no power supply. The finished gateways were installed together with the following sensors and relays:
