I have a couple ceiling fans in the garage that are plugged into a ST outlet. I would like to be notified when the fans have been left on for an hour. I have looked at all the smartapps and I don’t see one that will work. I would like one like Notify when something left open except it needs to be for an outlet left on. I would not like to use webcore if I don’t have to, I’m not too good at it. Thanks
Look into webCoRE. It will do all that you need.
If you use Smart Lighting to turn the ST Outlet on, you can use the Power Allowance feature to turn it back off after a certain amount of time. I know this isn’t exactly what you were asking, but thought you might find it useful.
