Fair point. When I bought my Hue lights, this turned out to be an unexpected pain point. Not only did guests routinely used the switch, I myself had a really hard time unlearning the habit of using it.

... and then I realized that using a phone instead of a switch is much less convenient. Because on poweroff, Hue bulbs revert to ugly, warm color (I bought the color ones to have some mood lights), I wrote a script that repeatedly queried the Hue bridge for color values of all bulbs and changed them according to presets I liked whenever it detected that a bulb has default color values. The script ran on always-on Raspberry Pi, which was plugged in solely for that purpose. Unfortunately, in order not to saturate the bridge with API calls, this script polled the bridge only every couple of seconds, which still made the accidental reset annoying.

All in all, my experience with smart lights turned out to be pretty disappointing. You really need a smart switch for them to make sense. An ideal smart switch would be stateful and have an actuator built in, so that its mechanical state always reflects the software state of the bulb. Unfortunately, I've never seen anyone make such switches.

The smart switches I'm used to are the wide paddle style and sit in the center, not the on or off positions, so you can always press either side. They also have a status light that shows on/off/dimmer positions as well.

Insteon 2477D is an example you can look up, though I don't recommend people go with the Insteon protocol for a new build.

A somewhat recent update to Hue bulbs lets you set up what they should do when they receive power, including the ability to tell them to just revert to the previous state. As stated in another comment however, I prefer them just turning on at (almost) full brightness, as I use the regular switch for turning them on when coming into a room.

Thanks for letting me know. I still have one Hue bulb in operation at our current place, though I unplugged the Hub and just deal with the ugly orange. This will be a good motivation to finally update the firmware (which I was avoiding for the past year), so that I can just fix the default color.
