My configuration until recently was an ISY 994i ZW+ IR PRO and a Polisy PRO running PG3 nodes servers. I moved off of the ISY 994i onto the Polisy Pro. So, now everything is on the Polisy Pro. Once the ZWave/Zmatter board is stable for all my Zwave devices, I'll buy an eisy and move everything over to it and get off the Polisy Pro. Since UD has announced dropping support this year for the ISY 994i, I'm sure that the Polisy will not be far behind. The 994i has been a great controller, but the weak link has been the microSD cards. I've had two microSD cards get corrupted and had to rebuild.
The remote control for the all the fans uses a single button to turn on and off the light. So, I'll probably not do anything with the lights via programs. With what you described regarding sync problems between the bond bridge and the remote control, it looks like more headache than it is worth. However, I can do some programming around the fans now.
