Although power failures rarely happen the controllers do have battery backups. Mine was disconnected for over a month this January when construction was being done on our garage and when I plugged it back in everything was "remembered." Some store the data (schedules etc) in "the cloud" so when power comes back it automatically downloads to the device. Plus if power is out so is irrigation even with a plain controller.
edit: ooops, thought you were referring to the WiFi irrigation controllers. I'm sure all the wifi type devices are pretty much the same. My WiFi pellet smoker barbecue controller does that as well as does my WiFi hose controller.
