Update the Pebble iPad to address self-unlocking door
My door was unlocking itself for a couple of months. Pebble replaced a wire harness, which worked for a bit, but then the problem returned. Pebble had me check that the iPad itself—not the app—was up to date, and it was not. Once I updated the iPad, the door has stayed locked. Not sure if this is related to what you are experiencing, but thought I'd share in case.
Seems like we are constantly having to push the “join Pebble Wi-Fi” button. It asks, but requires a tap to connect. Then often we have to close the Pebble app and try again, even if we didn't connect to home Wi-Fi in between. It's annoying.
