You're braver than I am. I won't use Hue bulbs because I require that my automation setup fail gracefully back to plain old 'just works the way it used to' functionality. It'd be just my luck that the server, hub, or Internet would fail right when I needed the lights to work and I'd be stuck in the dark.
My lights are all set to turn on after a power cut. That way if Home Assistant dies, I can flip any light switch off, then on, and it will work normally. My area doesn’t have any actual power cuts though.
Not really - these lights are always on, so if the hub croaks, your lights can still be turned on/off the old-fashioned way.
I actually got touch guards installed on all the switches so the guests don't press them - you can still poke it with a pencil and toggle. In almost 10 years, I have never had to do it.
The only drawback is that if the power goes in and out - all the lights come on. This is where remote functionality is useful, if you are away.
Hue bulbs by default emulate a dumb led bulb. This is configurable so you can have them be “dumb” in a way that you prefer, eg: customize color, brightness or do whatever you told them last.
I have several that some of the time I use a regular light switch to turn on/off and you wouldn’t know they weren’t standard led bulbs.
