Signal Booster

Do I need a ring router to use a signal booster as my signal booster cannot be found on my app when it’s plugged in . It’s black blinking slowly 3 times but I can’t find it in the app

Hi @user72795. You do not need a Ring router, which we actually do not have, to use any of our Ring Chimes. Which Ring Chime do you have? Is it the Chime Pro?
