I connected HS200 to the wall as specified. Orange and green light was flashing. I picked the tplink Wifi network in Kaaa app. Then it showed all the WiFi network available, but I didn't find mine. I tried few times with no success. Then I accidentally pressed the switch. It immediately started producing continuous tik-tok sound. I tried to reset button for 10-20 seconds, the sound did not stop. I pressed the restart button, no sound while the button was pressed but sound returned when released the button. What's wrong? Thanjs
