Meet the Pebblebee Stone: an item tracker and smart button to help you tag your stuff to be able to find them later. It has a motion sensor, so you can tell when your items have moved. Stone has a temperature sensor as well and lets you set notifications based on temperature.
Stone can also serve as a smart button for shortcuts. You can use the button to take a selfie or rely on IFTTT rules to do all kinds of things done with the press of a button. The companion app for Stone lets you set it up easily. Did we mention that Stone has a replaceable battery and a water resistant design? You can find out more about it on Indiegogo.
