If it's 30 minutes before sunset on weekdays, turn on my WeMo table lamp
This recipe turns on a Belkin WeMo powered table lamp 30 minutes before sunset on weekdays. To create the trigger, first create a HomeSeer virtual device and name it "30 minutes before sunset on weekends" (or whatever you wish). Then, create a HomeSeer event that will turn this virtual device on 30 minutes before sunset. You should also create a corresponding recipe and HomeSeer event to turn the virtual device and WeMo powered table lamp off at the time of your choosing.
