Hi, I have a project where I have built a hidden whiskey cabinet behind a panel in a wall.
The idea is to use an electro magnetic which will be powered on all the time much like a fire door in a hospital. When I want the door to open the electro magnetic would be switched off momentarily in order for the door to 'pop' open under spring tension. I would then be able to close the door and the electro magnetic would hold it closed as before!
Is there a way I can achieve this using a sonoff switch?
Thanks in advance for your thoughts.
