With multi-node Z-Wave devices, renaming has become tedious. None of the options to rename all the related nodes.
I find that I always want a common prefix. Unfortunately, when I create a device, there is no prefix.
At least provide an option to ADD a prefix to all associated devices.
And please consider putting a prefix on the names of Z-Wave devices to begin with, e.g.
ZW nnn.functional name or ZW nnn - functional name
