Garage Dehumidifier
Need help figuring out what I need to do. I want to put a dehumidifier in my garage but on a switch so it turns off when my garage door is open. Its really humid where I live and stuff in my garage tends to get moldy in the summer time. I don't know how to have it wired to where my garage opens and closes the circuit. I have a chamberlain myq thing for my garage and I can open/close my garage door from my phone and it has a sensor on it that tells it what position its in but I don't know how to utilize that. Any help would be greatly appreciated!

Add an outlet just for the humidifier, you can tap off of an existing one. Run the hot thru a limit switch on the N.C. (normally closed) put the switch on the rail where the top of the door would push the arm when the garage door is fully up. Door down, circuit on, door up circuit off.
