When your Wireless Tag PIR sensor has timed out it will turn off anything (light, TV, appliances) controlled by your WeMo switch.

This Trigger fires when specified PIR KumoSensor or regular motion sensor tag detects no movement for a time-out period.

This Action will turn a WeMo Switch off. If the WeMo Switch is already off, it will remain off.

Automatically turn off your WeMo switch when your Wireless Tag senses no one is at home
