Hey guys, I'm disappointed to see this one hasn't been resolved, as I've been having the same problems. I pull up in front of my house, typically see the message on my phone showing that I'm within the neighborhood (hello front door), and then nothing, 9 times out of 10 there's no auto-unlock. if I knock on my phone, I typically don't get an unlock either. sometimes i'll drop my phone in my back pants pocket, and the back door will unlock (its currently set to never auto-unlock), sometimes walking the dog I can hear it trying to trigger a knock-unlock. sometimes knocking on the phone unlocks the back door but not the front (?). if this device does anything reliably, it's that it makes me appreciate the simplicity of a physical, old-fashioned key.
