I have done a couple of hours of searching through threads concerning motion sensors and have a fairly good idea how to achieve what I want, but I also have seen so many ways to go about doing the same thing, I figured I would ask for others more experienced than myself for their opinions.
I have a motion sensor and a door sensor on my deck door. We let the dogs out of this door frequently (REALLY frequently) and what I want is if the door is closed when motion is sensed (when the dogs come back up to the deck door) a light inside the house blinks for a bit. I think I could probably have the blinking stopped once the door is opened. It's important to do because if the door is closed, they don't have a way to get back in and I don't want them scratching at the door.
Look forward to any suggestions.
Regards,
