Is your Hub, Router and Modem on a UPS? If not, then you aren’t going to ever get notified about anything because the rest of your ST infrastructure will be down and unable to do anything. That’s problem #1. Certain devices will not update their status in ST ever if there is no change to the state. For example, there are door sensors that won’t report back to ST for weeks if the door isn’t opened. I don’t know if the ST outlet falls into that category or not. You can try the smart app "Device Monitor. That might give you what you are looking for.
