  • Finally able to find group codes.....thx!

  • sensors didnot show up 

  • Do we need to call Livewatch to register the new sensors ?

  • "Sensors" option did not show up

  • Nevermind, I overlooked the verbiage found for step 4. If you don't see the "options" for sensors it's because you might be using your master code and not the installer code. 

    1. Apply your "Installer Code", which is "4321".

    Please note that your master passcode will not give you the option to add a sensor.
