The fans were purchased early on in the project and in storage for over 2 years so they are older models with the IR remotes.

Original plan was to take the guts out of the fans and use Lutron fan speed control RPM.  The electrical contractor and I spent half a day dissecting one.  These are complex fans so while it could have probably been done, it wasn't as simple as just removing a speed control unit like most less expensive fans have.

The electrician and contractor were also concerned about modifying the fans and nullifying the UL listing.  In the end, they were just switched with a relay module RPM to turn them on & off from the Lutron keypads and app.  Client has a remote hidden in drawer in each room if they want to change speed or rotation... the fans remember the last known setting when power is cut.

Hopefully the newer fans with SenseME and Alexa/Nest integration will open up some future integration options...
