Have your Google Assistant report the status of your fitbit and do not depend on the app anymore! You can ask Google if your fitbit is charged or not, or what is its battery status. Google will connect to the cloud and tell you all you need, so you won't have to open the app over and over again. This action is compatible only with Fitbit Ionic and the Fitbit Versa family devices. Take into account that you have to install the Full Battery app for Fitbit (version 2.1.0 or greater). The app can be downloaded by following this link: https://gallery.fitbit.com/details/a097edc3-a171-4a4c-8962-2110e7dfbeaa. Once the app is installed, you have to enable the Cloud AI integration feature.
