Hello how may I help you? I want to manage my home. What do you want to do? I want to do a simultaneous opening of my doors. Which doors? Well, when I open the front door, I want the garage door, kitchen door, and backdoor to open as well. Unfortunately I can't do that at the moment. That's unfortunate. I can only do one thing at a time That's not what I want. Thanks anyway. Hope you find the answer
