I have a 10 inch tablet mounted on a wall near the entryway of my house that controls the first floor lights, doors, garage and temperature. It monitors motion sensors to automatically lock up for the night when I head to sleep.
A little node.js server runs on the tablet to talk to the Vera’s API to poll and control all the various devices.
It’s fun stuff to play with if you can afford all the pieces. The other colored buttons along the bottom switch views to various business dashboards.
