Nuki Lock for ESPHome (ESP32)

This module builds an ESPHome lock platform for Nuki Smartlock (nuki_lock) that creates 6 new entities in Home Assistant:

• Lock
• Binary Sensor: Is Paired
• Binary Sensor: Is Connected
• Binary Sensor: Critical Battery
• Sensor: Battery Level
• Binary Sensor: Door Sensor
• Text Sensor: Door Sensor State

The lock entity is updated whenever the look changes state (via Nuki App, HA, or manually) using Nuki BT advertisement mechanism.

How to use

Add the following to the ESPHome yaml file:

esphome:
  libraries:
  - Preferences
  - https://github.com/vinmenn/Crc16.git
  - https://github.com/uriyacovy/NukiBleEsp32

external_components:
  - source: github://uriyacovy/ESPHome_nuki_lock

esp32:
  board: "esp32dev"  # Or whatever other board you're using
  framework:
    type: arduino
    version: 2.0.3
    platform_version: 5.3.0

lock:
  # Required:
  - platform: nuki_lock
    name: Nuki Lock
    is_connected: 
      name: "Nuki Connected"
    is_paired: 
      name: "Nuki Paired"      
  # Optional:
    battery_critical:
      name: "Nuki Battery Critical"
    battery_level:
      name: "Nuki Battery Level"
    door_sensor:
      name: "Nuki Door Sensor"
    door_sensor_state:
      name: "Nuki Door Sensor State"

After running ESPHome (esphome run <yamlfile.yaml>), the module will actively try to pair to Nuki. To set Nuki for paring mode, press the button for 5 seconds until the led turns on. Once Nuki is paired, the new ESPHome entities will get the updated state.

Supported Services

Unlatch

To unlatch doors without a handle, call open service from Home Assistant:

service: lock.open
data: {}
target:
  entity_id: lock.<NODE_NAME>

Lock and Go

To run lock and go, call this service from Home Assistant:

service: esphome.<NODE_NAME>_lock_n_go
data: {}

Unparing Nuki

To unpair Nuki, add the following to ESPHome yaml file below platform: nuki_lock section and run ESPHome again:

    unpair: true
