Sort of, they are piloting a program that will tell you when one of your devices stops connecting to the network. So if you lose power, then the device also stops connecting to the network and it would notify you that the device is no longer connected.
However, as I said this is a pilot program. You have to go into the account settings and manually turn it on for every device that you want it to do it for. In my experience, it only works for a couple of camera models and it’s not always very reliable at the moment. But it is something they are working on.
