It is mostly convenience (for me). I think most people talking savings are just trying to justify the toys.
I have a few smart switches that I can't say are anything more than convenience, but one smart plug paid for itself in 7 months and now saves me a whooping $4 per month on propane. A dumb timer would almost work, but the smart plug makes it so I can handle the exceptions to the rule.
