Just installed a U400 and UWB unlock on approach has never worked even once.
It does not unlock when I walk up to it from any direction. The only time it unlocks is when I touch the keypad to wake the lock, then it unlocks immediately. So credentials and Apple Home setup are clearly fine, but UWB proximity is not waking the lock at all.
Things already checked:
• UWB cable connected correctly
• UWB enabled in Apple Home
• Unlock on approach enabled in Apple Wallet
• iPhone 17 Plus + Apple Watch Ultra 2
• Bluetooth on
• Thread border router present
• Battery over 90%
Attached screenshots show unlock on approach is enabled on my phone.
This feels like either a firmware bug or a bad UWB module. Anyone else seeing this or get it working without touching the keypad first?
