Lighting hardwired to a stuck system and touching physical controllers (phone or otherwise) as you describe is one possible setup. On the contrary, I just have some table/floor lamps with smart outlets between their plugs and the outlets that can be quickly removed in case of failure, and touching my phone is only in case of voice (Google Home Mini) failure. Neither of which fail often, like much less than once a year. The convenience when half asleep is great.
