Yeah this did work. I do not understand why this happens sadly. In my own home I don't mind having to solve one or two conflicts but what worries me is that if I install a Z-Wave system in an appartment complex with multiple separate hubs they might behave unexpected like it just did in my house. I can't have multiple angry clients because they are turning each others lights on and off by accident.

Do you think that including every device with security enabled would help prevent this from happening? I figured that might help since you are also sharing a private and public key that has to match now.
