If you’re going for a cohesive ecosystem, consider hubs like Alexa or Google Home.
Don’t use closed corporate automation platforms that spy on you and require internet. For only a bit more work and research, you can make a much more customizable smart home that can survive an Internet outage and doesn’t have constant phoning home. Home assistant (!homeassistant@lemmy.world) is an amazing platform that I’ve been using for a few years, and I will never go back.
If you’re forgetful, smart bulbs can save money by turning themselves off after a timer expires or on a schedule. Or in my case, I have cats that have a litter box room and won’t use it in the dark. A smart bulb and a motion detector mean I don’t have to run a bespoke fluorescent bulb 24/7 to light the room (because that’s cheaper than replacing the fixture)
