The key fob's primary duty is to conveniently control scenes that you've set up in your Vera Dashboard. A scene typically includes multiple smart devices working together to do more than one thing. As an example, an "Arrive Home" scene might turn on the lights, move the thermostat to a preferred setting and turn off the entry way security sensors.

Each Scene that you create in your Vera system is assigned a number (in addition to any name that you give it, such as "Arrive Home," "Away For Weekend," etc.) Your key fob is capable of commanding up to 8 of these scenes.

You can control up to 8 scenes with just one button, depending on whether you click or hold the button.
