First of all, you can use the device as a regular kettle by simply pressing the first capacitive key, which has a great response.
In order to unleash those smart features, you have to connect the kettle to your phone via Bluetooth using the Mi Home app. I didn’t have any issues connecting my phone to the device but I didn’t like the fact that the app is in Chinese. The main smart feature is that the kettle has a built-in temperature control up to 12 h. Within the app, you can select e.g. that you want to keep the temperature of the water at 80 degrees from 1 to 12 hours.
