I have the beta firmware update. I literally just started what for me personally is the ultimate test - I'm pairing my old Zooz ZSE40 4-in-1s (500 series) directly to the C-7. It's VERY early (like, I paired it 2 minutes ago), but so far, it's already promising:
Paired on the first attempt with C-7 interface (i.e. NOT a Z-stick) - it paired automatically with no security.
I have a total of 5 of these and will slowly introduce them to the C-7 over the next week and we will see what happens. If you have no idea why this is a "test", just search the forums for a description of the kryptonite that these things were to the C-7 (yes, even when paired without security using a Z-stick).
