+## Pairing additional locks (Slot 2 and Slot 3)
+
+Nuki Hub supports up to 3 locks on a single ESP/device IP.
+
+To pair additional locks:
+- Go to "Nuki Configuration" and enable "Nuki Lock slot 2 enabled" and/or "Nuki Lock slot 3 enabled", then Save.
+- Go to "MQTT Configuration" and set "Lock Slot 2 MQTT Name" / "Lock Slot 3 MQTT Name", then Save.
+- Put the corresponding lock into Bluetooth pairing mode using the lock button.
+- Pairing for slot 2/3 is automatic while the slot is enabled and not yet paired.
+
+How this is shown:
+- On the info page, check "NUKI LOCK SLOT 2" and "NUKI LOCK SLOT 3" sections.
+- MQTT topics are published per slot name:
+  - `<mqtt_path>/<slot_1_mqtt_name>/...`
+  - `<mqtt_path>/<slot_2_mqtt_name>/...`
+  - `<mqtt_path>/<slot_3_mqtt_name>/...`
+
+Unpairing slot 2/3 in web interface:
+- Open "Credentials".
+- Use "Unpair Nuki Lock Slot 2" or "Unpair Nuki Lock Slot 3".
+- Enter the shown 4 digit confirmation code.
+

 Hybrid mode allows you to use the official Nuki MQTT implementation on a Nuki Lock 3.0 Pro, Nuki Lock 4.0, Nuki Lock 4.0 Pro, Nuki Lock 5.0 Pro, Nuki Lock Go or Nuki Lock Ultra in conjunction with Nuki Hub.<br>
