Have quite a few QSX jobs out there and I havent heard of any issues. But then again I am also the Lutron programmer and I always turn off auto updates on the Lutron side. They seem to think things should just update on their own for no particular reason. I have seen once or twice recently though that a Lutron processor will completely drop off the network and need a reboot to get it back online. Their engineering dept said the processor couldnt renew its IP from the router and reverted to local link address, and apparently it doesnt retry to grab an IP. Which is really poor design on their part.?
