I'd like to have an indicator light in our laundry room that can be controlled by an M1. This light would indicate when a garage door was open. Since wiring it would be a problem it would be nice if it were wireless, changing batteries wouldn't be a problem.
Rather than trying to reinvent the wheel I'd like to ask if anyone knows of a product that does this, or has fashioned something like this already and likes the result.
Anyone? Please share.
