LG GR-X247CSAV is a smart refrigerator that allows you to control and monitor your fridge remotely using a smartphone app. You can use the app to adjust temperature settings, diagnose issues, and receive alerts if there's a problem. The fridge also has a built-in Wi-Fi module that lets you connect it to your home network and control it using voice commands through smart speakers like Amazon Alexa or Google Assistant. Additionally, you can use the app to receive notifications about when the water filter needs to be replaced or when the door is left open.
