# Nuki Binding

This is the binding for the Nuki Smart Lock (opens new window).
This binding allows you to integrate, view, control and configure the Nuki Bridge, Nuki Smart Lock and Nuki Opener.

# Prerequisites

  1. At least one Nuki Smart Lock or Nuki Opener which is paired via Bluetooth with a Nuki Bridge. For this go and get either:
  2. The Bridge HTTP-API has to be enabled during Initial Bridge setup (opens new window).

It is absolutely recommended to configure static IP addresses for both, the openHAB server and the Nuki Bridge!

# Nuki Bridge Callback

The Nuki Binding will manage the required callback from the Nuki Bridge to the openHAB server if manageCallbacks is set to true. If manageCallbacks is not set it will default to true.
Make sure that you've selected the correct primary address in the network settings (opens new window).

If you want to manage the callbacks from the Nuki Bridge to the openHAB server by yourself, you need to set manageCallbacks to false. Then add the callback on the Nuki Bridge via Bridge API Endpoint /callback/add in the format http://<openHAB_IP>:<openHAB_PORT>/nuki/bcb.
The Sheet NukiBridgeAPI (opens new window) is a helpfull tool for listing, adding and removing callbacks.

# Supported Bridges

This binding supports just one bridge type: The Nuki Bridge (nuki:bridge). Create one bridge per Nuki Bridge available in your home automation environment.

The following configuration options are available:

Parameter Description Comment
ip The IP address of the Nuki Bridge. Look it up on your router. It is recommended to set a static IP address lease for the Nuki Bridge (and for your openHAB server too) on your router. Required
port The Port which you configured during Initial Bridge setup (opens new window). Default 8080
apiToken The API Token which you configured during Initial Bridge setup (opens new window). Required
manageCallbacks Let the Nuki Binding manage the callbacks on the Nuki Bridge. It will add the required callback on the Nuki Bridge. If there are already 3 callbacks, it will delete the callback with ID 0. Default true
secureToken Whether hashed token should be used when communicating with Nuki Bridge. If disabled, API token will be sent in plaintext with each request. Default true

# Bridge discovery

Bridges on local network can be discovered automatically if both Nuki Bridge and openHAB have working internet connection. You can check whether discovery is working by checking discovery API endpoint (opens new window). To discover bridges do the following:

  • In openHAB UI add new thing, select Nuki Binding and start scan. LED on bridge should light up.
  • Within 30s press button on Nuki Bridge you want to discover.
  • Bridge should appear in inbox.

Pressing bridge button is required for binding to obtain valid API token. If the button isn't pressed during discovery, bridge will be created but token must be set manually for binding to work.

If bridge is connected to network but not discovered, enter Manage Bridge (opens new window) menu in Nuki mobile app, check server connection then disconnect and let the bridge restart.

# Supported Things

This binding supports 2 things - Nuki Smart Lock (nuki:smartlock) and Nuki Opener (nuki:opener). Both devices can be added using discovery after bridge they are connected to is configured and online.

# Nuki Smart Lock

This is a common thing for all Nuki smart lock products - Nuki Smart Lock 1.0/2.0/3.0 (Pro) and Nuki Smart Door. The following configuration options are available:

Parameter Description Comment
nukiId The decimal or hexadecimal string that identifies the Nuki Smartlock. Only available in textual configuration, cannot be edited in UI.
deviceType Numeric device type as specified by bridge HTTP API - 0 = Nuki Smart Lock 1.0/2.0, 3 = Nuki Smart Door, 4 = Nuki Smart Lock 3.0 (Pro). Only available in textual configuration, cannot be edited in UI.
unlatch If set to true the Nuki Smart Lock will unlock the door but then also automatically pull the latch of the door lock. Usually, if the door hinges are correctly adjusted, the door will then swing open. Default false

# Supported Channels

Channel Type Description
lock Switch Switch to lock and unlock doors. If unlatch configuration parameter is set, unlocking will also unlatch the door.
lockState Number Channel which accepts Supported commands for performing actions, and produces supported values when lock state changes.
lowBattery Switch Low battery warning channel
keypadLowBattery Switch Indicates if keypad connected to Nuki Lock has low battery
batteryLevel Number Current battery level
batteryCharging Swtich Flag indicating if the batteries of the Nuki device are charging at the moment
doorsensorState Number Read only channel for monitoring door sensor state, see supported values
# Supported lockState commands

These values can be sent to lockState channel as a commands:

Command Name
1 Unlock
2 Lock
3 Unlatch
4 Lock 'n' Go
5 Lock 'n' Go with Unlatch
# Supported lockState values
State Name
0 Uncalibrated
1 Locked
2 Unlocking
3 Unlocked
4 Locking
5 Unlatched
6 Unlatched (Lock 'n' Go)
7 Unlatching
254 Motor blocked
255 Undefined

Unfortunately the Nuki Bridge is not reporting any transition states (e.g. for Lock 'n' Go).

# Nuki Opener

Parameter Description Comment
nukiId The decimal or hexadecimal string that identifies the Nuki Opener. Only available in textual configuration, cannot be edited in UI.

# Supported channels

Channel Type Description
openerState Number Channel for sending supported commands to Opener, produces one of supported values when Opener state changes
openerMode Number Id of current Opener mode, see Supported values
openerLowBattery Switch Low battery warning channel
ringActionState Trigger Channel triggers 'RINGING' event when the doorbell is being rung. This can trigger at most once every 30s

# Troubleshooting

# Bridge and devices are offline with error 403

If secureToken property is enabled, make sure that time on device running openHAB and Nuki Bridge are synchronized. When secureToken is enabled, all requests contain timestamp and bridge will only accept requests with small time difference. If it is not possible to keep time synchronized, disable secureToken feature.

# NukiId conversion when migrating from old binding version

Older versions of binding used nukiId in hexadecimal format (as displayed in Nuki app, e.g. 5C4BC4B3). The new version expects nukiId to be in decimal format (e.g. 1548469427), since that's the format returned from API. The binding does the conversion automatically, but only if your nukiId contains any letters A-F, otherwise the binding has no way to tell whether the id is in hexadecimal or decimal format. If your nukiId in hexadecimal format contains only numbers, you'll have to convert it to decimal format manually, or preferably delete the old Thing and use discovery to recreate it.

# Full Example

A manual setup through files could look like this:

# things/nuki.things

    Thing smartlock SL1 "Nuki Smartlock Name" [ nukiId="12AB89EF", deviceType=0, unlatch=false ]
    Thing opener OP1 "Nuki Opener Name" [ nukiId="254CF45A" ]
