Vertical garage door

Recently moved to a house with a vertical garage door. In the old house, we had the RE tilt sensor to monitor position and the GD gaarage door controller. Since both of these rely on the garage door tilting to 45 degrees, what options do we have now? The garage door has virtually no tilt.

The open is a Liftmaster 8500 series.

Options to monitor garage doors are described here.

If you are looking to actually monitor it for alarm purposes, we would recommend the second option on that page, which will work for most any door style.
