Smart bulb rationalization:
I first got a set of 3 smart bulbs for my kitchen counter, because of a poorly placed wall switch. This was a good solution to the problem.
Then I realized I could adjust the brightness. A very nice bonus for these lights, and I could replace the bulbs in 3 other sets of lights on sliders that only really worked for incandescent bulbs. Not only could I finally replace the old bulbs with LEDs, but I could adjust them by voice.
Now with more bulbs in place, I set up a schedule to turn some of the lights on in the evening and off at bedtime, for both convenience and home security if I was away. I could use lamps with mechanical timers, but as days get longer or shorter you have to continually adjust them. And if the power goes out, the timer is off by however long it was out. With smart bulbs, I can set them up to come on 10 minutes before sunset, so it's set and forget, and even if I turned up the brightness the day before, it comes back on with the brightness I give in the smart routine.
Ooh, colors! Why settle for various degrees of white, when there are so many other colors available? While it's mostly aesthetic, in summer bug season I have my deck and porch lights to yellow, and change them back to white over winter for better visibility when grilling in the dark. And don't discount the pleasantness of using non-white colors inside.
There's convenience and safety too. If I have my hands full it's a lot safer to tell Alexa to turn on a room's lights than to try to get it with a shoulder or stumble around in the dark. And if I need to, I can give Alexa a command to turn on every smart light in the house, full intensity, assuming power and internet are on.
I totally get that some people won't allow Alexa or Siri to listen at their house. I'm not trying to convince anyone to give in. I'm just saying it's far from me being too lazy to use light switches.
