The SmartThings Find network and the SmartTag2 work together to help you keep track of your stuff. The SmartTag2 uses ultra-wideband (UWB) technology to communicate with your device, so you can quickly and accurately find what you're looking for. The SmartThings app will notify you when your SmartTag2 leaves the network, so you can easily keep track of your items. The IP67 rating means that the SmartTag2 is dustproof and can be submerged in 1 meter of water for 30 minutes.
