Ano, I don't think you quite appreciate the difference between HA working 100% of the time versus 80% or even 95%. If you wish to have automation that is installed once and used for at least a decade with only minor maintenence, the hard-wired is the only way to go. UPB is a great technology, but it does not work in 100% of cases, it also depends on specifics of the house. And you can also only do certain things with it. I can program any button in my system to run a sceen that involves 100 lights set at various levels, all shades, audio, video etc. etc plus other sceens with one press, no skipping, no misses, just works, and works every time. Try that with any other lighting technology. Hard wiring is also great for everything else: its cheaper, more reliable and no need to change the batteries. In the long term hard wire wins on all counts, but up-front it usually appears more expensive. In my experience with almost all kinds of HA technology I found that the more devices you add to a wired set-up, the better the automation becomes, but the opposite is true with wireless after some small threshold, like 50 devices.
