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.

Cheapo wireless doorbell

eg

http://www.ebay.co.uk/itm/New-Wirele...#ht_860wt_1091



with the pushbutton changed from a normally open type, to a normally
closed one, maybe ? Mounted inside on the door frame, with a little tab
of springy metal to push the switch when the door was down. You could
even power the transmitter from a mains supply inside the garage, to
save having to bother about making sure the batteries were always good.

It's an idea but I thought to use a light because anything noisy could
cause problems on days when the door is left open deliberately for access
to things like the lawnmower.

Err, yes ... It was just a cheap way to get a wireless link. You don't have
to actually use the sound that the indoor unit makes. It would be fairly
easy to just disconnect the speaker, and look for a voltage that shifts
level when the outdoor unit transmits. Use that to drive a small relay to
switch whatever you like. However, if you are not an electronic-savvy DIYer,
I can understand that the mods required might be more of a challenge than I
had considered.

OK. Furry nuff. Lots of the people on here are electronic-y types and I do
it for a living, so I sometimes forget that it might be a foreign language
to others ... :-)

Sorry for adding confusion to the mix !

No confusion added, and thanks for the suggestion. I understand what
you're suggesting, I just doubt my ability to make a neat and competent
job of it!
