Smartwatches are gaining in popularity as they are more affordable and offer good and easy APIs for developers. Moreover, they are easier to use in everyday actions. I published some time ago Open Sesame project that aims to enable the control of the doors using a Smartphones. In this project, I propose an application for pebble watches to control this system.
Now, when I back home from the grocery store with bags in my hands, I just use the watch while keeping my mobile device in my pocket 😀
