Abstract: A method for automation and control of a wireless device in a WiFi environment. The method includes a wireless mobile device configured with a soft access point (softAP) transmitting probe requests to home automation devices and traditional stationary access points. The wireless mobile device periodically wakes up to scan for other services, sends a probe request, authenticates the received probe response from the another device and receives control information via the received probe response.
