The fallback doesn't have to change the state of the switch. Just leave the state alone on disconnect/reconnect from the network/controller. In the case of power outages where the whole device loses power... presumably these devices have some sort of nonvolatile memory and can afford to keep track of their last state. That's one bit for a basic on/off switch. :)
