Re: Dumb light bulbs aren't so dumb
My dumb light bulbs have a great ambience function. Via a knob on the wall, I can increase and decrease brightness at will, allowing me to set the ambience however and whenever I want.
Nice.
I live in a rental home. Such a knob requires written permission from the landlord, which requires an application. Said application requires stuff from the electrician - who of course must come out to install it and later provide certification of the completed job (which, is the LL is anal enough, may require a separate electrical inspector to sign off on). Probably at least a couple of grand to do.
VS the 'smart bulb' which I can fit myself...
(FWIW, I use the normal manual light switches as they're all I need - and appropriate brightness of bulbs in rooms)
(NOT saying they're a good thing, just saying that there's a whole lot of different costs involved in changing what's in the socket vs changing what supplies the socket :) )
