Secuyou Bluetooth Smart Lock Binding for openHAB

This extension adds support for Secuyou Smart Lock for terrace doors.

Supported Things

Following thing type is supported by this extension:

Secuyou Smart Lock model 2.21

The lock must already have been setup in the Secuyou app.

NOTE: Only tested with a single lock of model 2.21 and firmware version 6. Might work somewhat on older models.

NOTE2: Flaky firmware; sometimes when manually locked by touching the device, the lock reports UNKNOWN/IN PROGRESS status (neither LOCKED nor UNLOCKED) for a while. In the app this can be seen as a grayed out lock symbol while still reporting that the phone is connected to the lock.

NOTE3: Make sure you have set "Home Lock" to true - or the lock will assume your BLE dongle is a nearby phone and not trigger auto locking.
