This skill enables Alexa to feed the dog when you aren't home through an IoT device. just say, "Ask dogfeeder to feed the dog" and it does the rest. it also can control lights with other commands such as "Ask dogfeeder to turn lights on" and "Ask dogfeeder to turn lights off". (additional 3rd party IoT device such as a raspberry pi and dogfeeder required).
