SmartThings Device Battery Level Decreased from 100 Immediately

If the SmartThings Tracker is reinitialized, it will be reset. To do so, you must delete the tracker from the SmartThings app. When it's deleted, it will initialize itself so it can reconnect to SmartThings. At which time, you'll be able to connect and register the tracker with any Samsung account. 

SmartThings will occasionally push firmware updates to active hubs to improve performance. You can check the hub's firmware version using the app or the IDE Portal.

If your ZigBee device is not working with your hub, be sure to check the power to the device and the hub's network connection. However, it may be necessary to reset the ZigBee device and restart the hub to fix the problem.

If your SmartThings Wifi or Connect Home hub is frozen and not emitting a Wi-Fi signal, rebooting the hub may fix the problem. However, you may need to restart the SmartThings app and checking your network connection.

If the Hub loses power or internet connection, there may be limited or no functionality. Each Hub version reacts differently in the case of a power or internet connection failure.
