With this radio frequenzy remote set you can open your window from a distance of up to 10 meters.
The default setting is not auto-close but it can easily be adjusted, so the window opener closes automatically after 5, 15 or 60 minutes, its up to you!
A perfect solution in e.g. bath rooms, where the humidity is high or simply as a secure measure to avoid windows open too long.
