Connectivity features are usually present in high-end refrigerators. Although you can buy a simple yet well-featured model, it wouldn’t hurt to spend more if you want to have the specific features that come with a smart refrigerator.  With the use of WiFi connectivity and an app, you can receive important alerts, schedule your hot water, easily adjust the temperature, and add memos. Certain models such as the PVD28BYNFS and the PYE22PYNFS come with a built-in WiFi connectivity option, and they can be controlled using your voice or through virtual assistants such as Google Assistant and Alexa.
