I have a keypad that i have successfully added to my Ring system twice now. After adding it, i check that it works by arming/ disarming the system using this keypad. Then a few hours later, the keypad will factory reset all by itself. I see in the system’s Event History these three consecutive events: 1) keypad factory reset, 2) keypad offline, 3) keypad removed from system. How do i fix this?
