You can just do little things. I bought some WeMo smart outlets that plug in to regular sockets- basically a WiFi lamp timer. They have been a pleasant upgrade to old fashioned dial lamp timers, easier to change the schedule, trigger with sunrise/sunset, etc. You can combine them with all sorts of appliances. For example, I'm always irked how much idle power my garage door opener draws. Well, I could throw a smart switch inline to shut it off at night, and in the event of late night door usage I can override the schedule with my phone.

If they were to fail or EoL, I'd be out some money but all you have to do is unplug them.
