I wanted to report that we successfully installed and added to our system a "Smart Glass" using an ApplianceLinc. Long story short, we were tired of the wooden blind banging on the glass and making noise every time the patio door was opened/closed, so we started researching about the new products (film or glass) that switch between clear and opaque and are being used in airplanes and cruises. This is one of the companies that makes them: https://www.smartglasscountry.com/
We decided to pull the trigger and installed some film on our door. Ordered a KeypadLinc and an ApplianceLinc to attach to the transformer and the results are great. I will try to post some pictures when there is daylight.
