Alternatively, you could simply not have a "smart home" in the first place, saving money, hassle, and having to worry about issues like this.
Which, ironically, is a pretty smart choice.
A smart home is technology for the sake of technology, not solving a need as such.
Mostly they're smart because they save on wiring. For a while I've had all of my living room lighting (ceiling, as well as standard lamps and a table lamp) all Hue so they get turned on and off together. Standalone and useful. I've been experimenting with HA running on a Pi because I want to do a slightly complicated combination of PIR and timing for some outside security lights and it'll be trivial with HA.
My Philips Hue bulb was replaced with a dumb one when it crapped out and I turn it on and off with a telescoping pointy finger that lives next to my bed ;)
The moment you make it clever past this you incur the overheads of the whole system production in the efficiency cycle. That means the manufacture and distribution of a complex computer system.
Never know what will be normalized in the next generation. Or what will be considered crazy later on.
