We've got an offline setup, using HA, HomeKit and zwave. Some of the best features for us: - ability to turn on house heat when we're headed home from a trip, or turn on the AC for the pets if there's a heat wave when we are traveling. - ability to turn on the tea kettle when driving back home from an errand. Needs prior setup of course, and a switched outlet that can handle high current. - ability to align porch light schedules with sunset/sunrise. I never have to think about it. The "don't want to get up, i'll just do it from my phone" thing is nice, though, especially if you are stuck under a cat.
