Thanks for your reply, particularly about how the device / iOS app saw my Network. Seeing it through my iPhone makes sense. ...I feel more confident about letting the device remain in place, since it's working (presently) as I wanted.
One thing I've done in my AE, is to limit the device's access to the Network for specific hours of the day/night. This was mainly a test and during the period the smart plug has no access, it's power - connection light is Off (the iOS app showed the device offline).
...Once the device was again on the Network (and connection light back On), the iOS app saw it and made the On / Off screen available.
...That's mainly the AE's doing, but between it & the iOS app, it's nice to have this communication working smoothly.
For $20, I'm happy. ...So far.
