The answer is easy: no! KiddieAlarm requires WiFi to be set up and we advice you to keep your KiddieAlarm connected to WiFi as much as possible so it will be easier to operate and will auto install software updates. But it never generates WiFi signals. Instead it only consumes the WiFi signals already available in your house.
If you want to limit the amount of WiFi/radio signals in your house it does not help turning off the KiddieAlarm. Instead it helps turning off your WiFi/Internet modem, router or access points. Those are the once generating WiFi signals.
KiddieAlarm can perfectly handle a WiFi outage. Meaning if you decide to turn off WiFi during the night for instance to limit the amount of broadcasted signals that KiddieAlarm will be perfectly safe and keep operating as it used to with WiFi available. And as soon as you put on your WiFi network again in your house KiddieAlarm will pick it up and continue working online.
