Need 'Window is Still Open' reminder buzzer/chime
There is a window that gets open at night to allow air circulation, but the blind is closed for privacy. The next morning the open window is forgotten about and the person in that room leaves the house oblivious that the window is still open.
I'd like to get a sensor on the window and the exterior doors that will set off a buzzer when the exit door is opened while that window is still open to remind the person to go back and shut the window before they leave the house.
Does anyone have recommendations on something easy to install without needing to install a complete alarm system?
