Turn off a group of devices when #OhmHour starts
Instead of turning off a single device, you can turn off a group of devices. Using the Smart Life app, create your own scene without a condition, then add each device under task, turning each device off. Name the scene something like "Devices OFF". Then select the scene using the IFTTT applet. In the future, you can add or delete the devices using your Smart Life app. When #OhmHour starts, this Applet will trigger the Smart Life scene, turning off all the devices you put into the scene!
