Why did I fail to set up my Onvis Smart Contact Sensor CT3 to Onvis Home app?
(1) Make sure Bluetooth is enabled in your iOS device.
(2) Make sure your CT3 is within connecting range of your iOS device.
(3) Before set up, reset the device by long pressing the button for about 10 seconds until green LED blinks 3 times.
(4) Scan the setup code on the device, instruction manual or inner packaging.
(5) If the app prompts ‘‘couldn’t add the device” after scanning the setup code:
a. remove this CT3 that was added before and close the app;
b. restore the accessory to factory settings;
c. add the accessory again;
d. update the device firmware to the latest version.
