We've got a new sectional garage door that's for ever being left open if
the button to close it isn't pressed as soon as we've finished with it
and are back in the house.
Has anyone got a simple warning light solution that I could install
inside the house that will illuminate when the door has been left open.
Preferably not requiring wiring being installed as I've just tidied up
after wiring the button.
And yes, I know it's much simpler just to remember to press the button
to close it, but it's not happening.
