By wiring it to the outside door light it had the unexpected benefit of letting me know the outside light has been left on because it won't display then.

I'm curious why the outside light has to be off for the voltmeter to work. That's opposite to what I would expect. :h

You are correct- when the light is on the meter is off. I didn't realize it would do that but I'm glad it does.
