This ioBroker adapter (formerly ioBroker.Nuki2) allows to control and monitor the Nuki Smart Lock and / or the Nuki Opener by using both the Nuki Bridge API (v1.9.0, 06.05.2019) and the Nuki Web API (v1.2.0, 31.05.2019).

- Support for Nuki Smartlock and Nuki Opener
- Support for both Nuki Bridge API and Nuki Web API
Support for hashed token on hardware bridges (see https://developer.nuki.io/page/nuki-bridge-http-api-190/4#heading--token)- Fallback to Nuki Web API in case applied actions on Nuki Bridge API fail, e.g. due to bridge error 503 (see https://developer.nuki.io/t/random-http-503-unavailable/909/85?u=zefau)
- Retry in case applied actions on Nuki Bridge API fail (when Nuki Web API is not used)
- Option to regularly synchronise instead of using Bridge API callback (which may be delayed due to Hardware Bridge)
- Refreshing all states of Nuki Web API when callback is received via Nuki Bridge API
- Retrieve authorised users for Nuki Smartlock and Nuki Opener (see below Channels & States)
- Retrieve the configuration for Nuki Smartlock and Nuki Opener (see below Channels & States)
- Retrieve setup Nuki Notifications (see below Channels & States)
- Web Interface that shows the recent events from your Nuki Smartlock and Nuki Opener:
How to get your hardware bridge token (does not work for software bridges):
- Call
http://<bridge_ip>:<bridge_port>/auth
from any browser in your network. The bridge turns on its LED. - Press the button of the bridge within 30 seconds.
- Result of the browser call should be something like this:
{ "token":"token123", "success":true }
- Use the generated token in the nuki-extended adapter.
Do the following, to use the Nuki Web API:
- Retrieve a token at https://web.nuki.io/de/#/admin/web-api
- Use this token in the nuki-extended adapter
- Make sure your nuki devices are published on the Nuki Web API (use the Smartphone App via Settings
Activate Nuki Web
)
If you successfully setup ioBroker.nuki-extended, the following channels and states are created:
A bridge will be created as device with the name pattern bridge__<name of bridge>

schedule('0 22 * * *', function()
{
var status = (getState('nuki-extended.0.smartlocks.home_door.state.lockState').val);
var msg = 'Main Door door is ' + (states[status]) + '. ';
if (status == '3')
{
setState('nuki-extended.0.smartlocks.home_door._ACTION', 2);
msg += 'Locking door..'
}
else
msg += 'No action taken.'
log(msg, {m: 'Nuki', o: ['msg']});
});
Replace nuki-extended.0.door__home_door.status.lockState
with the lockState of your lock! You may also customize the message via msg
.
This requires the ioBroker adapter ioBroker.alexa2 (https://github.com/Apollon77/ioBroker.alexa2).
In order to use the voice output of Alexa we define a function say
. Place the following function in a script in the "global" folder of ioBroker.javascript. IMPORTANT: Replace #YOUR ALEXA ID# (also replace #) with your Alexa ID. You may find the Alexa ID in the Objects tree of ioBroker alexa2.0.Echo-Devices
.
/**
* Say something with Alexa.
*
* @param {string} message Message to say
* @param {string|array} alexas Alexa Device to say the voice message
* @return void
*
*/
function say(message, alexas = '#YOUR ALEXA ID#') // use alexas = ['#YOUR ALEXA ID 1#', '#YOUR ALEXA ID 2#'] for default voice output from multiple devices (also replace #)
{
alexas = typeof alexas === 'string' ? [alexas] : alexas;
alexas.forEach(function(alexa)
{
setState('alexa2.0.Echo-Devices.' + alexa + '.Commands.speak', message);
});
}
You can use this function within ioBroker.javascript to say a phrase using Alexa say('Hello World')
or say('Hello World', ['#YOUR ALEXA ID 1#', '#YOUR ALEXA ID 2#'])
for voice output from multiple devices.
Create a script in the "common" folder of ioBroker.javascript and add the following listener to it. IMPORTANT: Replace #LOCK STATE ID# (also replace #) with the state holding the lock status (e.g. nuki-extended.0.door__home_door.status.lockState
):
const DOOR_STATES = {
"0": "uncalibrated",
"1": "locked",
"2": "unlocking",
"3": "unlocked",
"4": "locking",
"5": "unlatched",
"6": "unlocked (lock n go)",
"7": "unlatching",
"254": "motor blocked",
"255": "undefined"
};
/*
* LISTEN TO CHANGES TO LOCK STATE
*
*/
on({id: 'nuki-extended.0.smartlocks.home_door.state.lockState', change: 'any'}, function(obj)
{
if (obj !== undefined && obj.state !== undefined)
say('Door is ' + DOOR_STATES[obj.state.val] + '!')
});
This requires the ioBroker adapter ioBroker.telegram (https://github.com/iobroker-community-adapters/ioBroker.telegram).
In order to use the message output of Telegram we define a function msg
and messenger
. Place the following function in a script in the "global" folder of ioBroker.javascript:
/**
* Send something via telegram.
*
* @param {string} message Message to print
* @param {string|array} receiver Users to send the message to
* @return void
*
*/
function msg(message, receiver = 'ALL')
{
if (receiver == 'ALL')
messenger(message);
else
{
receiver = typeof receiver == 'string' ? [receiver] : receiver;
receiver.forEach(function(user)
{
messenger(message, user);
});
}
}
/**
* Sends a message / text.
*
* @param {string} content Message to send
* @param {string} user (optional) Specific user to send the message to (defaults to all registered users)
* @return void
*
*/
function messenger(content, user = '')
{
var config = {
text: content,
parse_mode: 'HTML',
reply_markup: {
resize_keyboard: true,
one_time_keyboard: false
}
};
sendTo('telegram', user ? Object.assign({user: user}, config) : config);
}
You can use this function within ioBroker.javascript to send anything to Telegram via msg('Hello World')
(to all users) or msg('Hello World', 'Zefau')
(to specific users).
Create a script in the "common" folder of ioBroker.javascript and add the following listener to it. IMPORTANT: Replace #LOCK STATE ID# (also replace #) with the state holding the lock status (e.g. nuki-extended.0.door__home_door.status.lockState
):
const DOOR_STATES = {
"0": "uncalibrated",
"1": "locked",
"2": "unlocking",
"3": "unlocked",
"4": "locking",
"5": "unlatched",
"6": "unlocked (lock n go)",
"7": "unlatching",
"254": "motor blocked",
"255": "undefined"
};
/*
* LISTEN TO CHANGES TO LOCK STATE
*
*/
on({id: 'nuki-extended.0.smartlocks.home_door.state.lockState', change: 'any'}, function(obj)
{
if (obj !== undefined && obj.state !== undefined)
msg('Door is ' + DOOR_STATES[obj.state.val] + '!')
});
NOTE: If you are using both the Alexa and the Telegram script, you may only define one listener for both actions:
const DOOR_STATES = {
"0": "uncalibrated",
"1": "locked",
"2": "unlocking",
"3": "unlocked",
"4": "locking",
"5": "unlatched",
"6": "unlocked (lock n go)",
"7": "unlatching",
"254": "motor blocked",
"255": "undefined"
};
/*
* LISTEN TO CHANGES TO LOCK STATE
*
*/
on({id: 'nuki-extended.0.smartlocks.home_door.state.lockState', change: 'any'}, function(obj)
{
if (obj !== undefined && obj.state !== undefined)
{
say('Door is ' + DOOR_STATES[obj.state.val] + '!')
msg('Door is ' + DOOR_STATES[obj.state.val] + '!')
}
});
This requires the ioBroker adapter ioBroker.telegram (https://github.com/iobroker-community-adapters/ioBroker.telegram) and the ioBroker adapter ioBroker.alexa2 (https://github.com/Apollon77/ioBroker.alexa2).
/*
* Alexa and Telegram to notify on Opener Ringing state
*
*/
let phrase = 'Somebody is ringing the doorbell.'; // Es hat an der Tür geklingelt
on({id: 'nuki-extended.0.openers.opener.state.ringStateUpdate', change: "any", ack: true}, function (s) {
