I never heard anything from Leviosa. I thought I might as they asked me to join their beta program for the Zone firmware. I had, I thought, a pretty good back and forth with one of the developer's on some issues, but never heard back from them.
My Zone quit working and I had a Bond hub that I was using for a Fan my wife had bought for our bedroom and instead of buying another Zone I decided to try using the Bond hub to control the shades. I am using the HE Bond integration and it works really well with the shades.
I did make a slight change to the driver. The current drive only allowed you to open or close I added a raise and lower which moves the shade to the next setpoint.
