If the power goes out or the router gets funky, most internet connected solutions would go offline anyway. But, being battery powered, Point would at least still be active and keep track of things. The fact that the device has lost it's connection to the cloud will trigger a notification to the owner as well. The wireless configuration is done using an app and should be straight forward for most users. As long as the router is securely configured and the user is capable to connect a phone or laptop, installing Point should be piece of cake. As for being self-contained, we mean that it is plug-and-forget, without any cables or base stations. There might be methods of expanding the set of sensors, although at the moment, you see what you get. Adding a cellular modem to the device would make it deviate too much from our current concept in terms of cost (both manufacturing and recurring costs for the cell network usage) and power consumption, but it is something we might include in a future, special version for places without a permanent internet connection, like a cabin or boat.
