Nothing on there is really crazy or complex. Just things like running the Roomba when I leave, or turning on lights at sunset.
I’ve found it to be very nice because I can automate common things around temperature, motion, waking up/falling asleep, and leaving/coming home. It also all integrates with HomeKit so I can control everything with Siri.
It’s definitely more in the hobby territory than something truly essential, but I would say that it is definitely useful and better than managing a bunch of random apps to automate lights or whatever.
