Turning something, anything on and off a few times seems well within the design limit for such a device. If a standing desk and shredder can handle that, then a smart meter should very much also be able to. None of this was your original point, anyway. You instead chose to focus on a completely different and irrelevant failure case. There is a world of difference between "voltage regulation issues might cause major problems" (your point) and "turning the thing on and off too quickly causes the whole thing to self-destruct" (the actual point).
