**Auto-lock after the door closes:**  Introducing the new open sensor that enables auto-lock after the door closes, replacing the previous timer-based auto-lock function. It notifies you of any changes in the open/closed status. Not just for doors - with customization, the possibilities are endless for drawers and any area that opens and closes.

## Enhanced Software Features:
1. **Open Sensor Lock** function: Adjustable grace period from 0 seconds to 1 hour. Set how many seconds after the door closes before it locks. (If the door opens before Sesame locks, the countdown resets.)
2. When using both **Open Sensor Lock** and Sesame's built-in **Timer Auto-Lock**:
   - If the door is open, the **Timer Auto-Lock** is disabled and won't activate even after the set time.
   - Once the door closes, the **Open Sensor Lock** function takes over.
   - If Sesame is unlocked without door movement, the **Timer Auto-Lock** remains active.

- **Remote notifications:** Receive notifications remotely when paired with Hub3.
- **Matter compatibility:** Can support Matter protocol when connected to Hub3.
- **Sesame connectivity:** 1 Open Sensor can be linked with up to 2 Sesame devices.
- **Compatibility Notice:** While not currently compatible with original Sesame, SESAME mini/3/4, please use SESAME 5/5Pro for immediate enjoyment with SESAME.
