Works with full table
Nuki locks talk to a phone over Bluetooth. For remote access and voice control there are two routes: Matter over Thread on the newer locks (Go, Pro, Ultra and the 4th generation), which works with a Thread border router such as an Apple TV, Nest Hub, Echo or SmartThings hub, or Nuki's own cloud service, Nuki Web, reached through a Nuki Bridge or a built-in Wi-Fi module on models that have one.
That suits anyone who wants a lock that appears natively in Apple Home, Google Home, Alexa, SmartThings or Home Assistant, and people who like to script their own integrations: Nuki publishes a cloud Web API, a local Bridge HTTP API and MQTT support. Older locks without Matter rely on the Bridge or on Nuki Web, so the cloud and a separate accessory become part of the setup.

The main app for setup, sharing access, activity log, Auto Unlock, Auto Lock and Night Mode. It is also where Matter is activated. Published by Nuki Home Solutions; the iPhone listing mentions Apple Watch and the Android listing mentions Wear OS. Nuki Web, the company's cloud service, is a separate web-based service rather than an app, and we found no other official Nuki app listings.

| Platform | Status | What it means | Sources |
|---|---|---|---|
| Connection | |||
| Bluetooth | Yes | Nuki's Matter guide says the phone must be within Bluetooth range of the lock to activate Matter, and the Web API page describes a Nuki Bridge that forwards commands to the lock over Bluetooth. | Nuki Matter setup guide Nuki Web API |
| Wi-Fi | Yes | Nuki's Matter guide refers to remote access that works without a Bridge or built-in Wi-Fi module, and says Nuki does not plan to support Matter over Wi-Fi. A Nuki Bridge or built-in Wi-Fi connects the lock to Nuki Web. We did not find a Nuki page listing which models have built-in Wi-Fi. | Nuki Matter setup guide |
| Thread | Yes | Matter over Thread is supported on Smart Lock Ultra, Pro, Go and the 4th generation. A Thread border router is needed, such as an Apple TV 4K, HomePod, Nest Hub, certain Echo or eero devices or a SmartThings hub. | Nuki integrations help article Nuki Matter setup guide |
| Zigbee, Z-Wave | Not mentioned | Neither is mentioned in the Nuki pages we opened. | Nuki integrations help article |
| Matter | Official | Nuki says Matter over Thread works with Apple Home, Google Home, Alexa and SmartThings. Matter is switched on in the Nuki app, and the connection cannot be undone once deleted, so it must be set up again from scratch. Home Assistant lists Smart Lock Go, Pro (5th generation) and Ultra as its supported Nuki Matter models. | Nuki Matter setup guide Home Assistant: Nuki Matter |
| Voice assistants and ecosystems | |||
| Google Home | Official | Supported through Matter over Thread, and listed by Nuki under its Nuki Web integrations. Nuki's page describes voice control, status checks and routines. Not all Nest devices act as Thread border routers, and Nuki notes only Nest Wifi Pro supports remote access over Thread. | Nuki integrations help article Nuki integrations page Google Home compatible devices |
| Amazon Alexa | Official | Supported through Matter over Thread and through Nuki Web. Nuki's page says the lock must be connected via Nuki Web for the Alexa route, and mentions voice commands and Alexa routines. | Nuki integrations page Nuki integrations help article Alexa Skills store |
| Apple Home | Official | Smart Lock 2nd and 3rd generation connect to Apple Home using HomeKit over Bluetooth. Smart Lock Ultra, Pro, Go and the 4th generation use Matter over Thread. Nuki's page mentions Siri, Apple Watch and location or time based automations. | Nuki integrations help article Nuki integrations page Apple Home accessories list |
| Samsung SmartThings | Official | Nuki lists SmartThings under Matter over Thread, and its Matter guide names SmartThings Hub v3, SmartThings Station and Aeotec hubs as Thread-capable. A separate community Edge driver exists for locks used with a Nuki Bridge, written by an individual developer. | Nuki Matter setup guide SmartThings community Edge driver |
| IFTTT | Official | Nuki published an IFTTT integration. It needs Nuki Web activated in the Nuki app and the lock connected through a Nuki Bridge. The page gives example applets rather than a full trigger and action list, and carries no date. | Nuki IFTTT announcement |
| Philips Hue | Not mentioned | No direct integration found. Nuki's IFTTT announcement uses turning off Philips Hue lights when leaving as an example applet. | Nuki IFTTT announcement |
| Open platforms and developer access | |||
| Home Assistant | Official | Two routes. The Nuki Matter integration works locally over Thread, and Nuki is a Works with Home Assistant partner for Smart Lock Go, Pro and Ultra. The older Nuki Bridge integration, which Home Assistant contributors maintain rather than Nuki, talks to a Nuki Bridge over its local HTTP API (Local Polling). Nuki links to Home Assistant from its own integrations page. | Home Assistant: Nuki Matter Home Assistant: Nuki Bridge Works with Home Assistant announcement |
| Homey | Official | Athom publishes an app marked Official on homey.app. Its page lists Homey Cloud, Homey Pro, Homey Pro mini and Homey Self-Hosted Server, and states that every listed Nuki device (Opener, Smart Lock, Smart Lock Go, Pro 4th and 5th generation, Ultra and the MQTT Smart Lock) requires a Homey Bridge. Flows cover lock and unlock, and Keypad PIN management for the Smart Lock. | Homey Nuki app |
| openHAB | Yes | The Nuki binding is in openHAB's own add-on list and covers Smart Lock (1.0, 2.0, 3.0 Pro and Smart Door) and Opener. It needs a Nuki Bridge with its HTTP API enabled and talks to it over the local network. Nuki does not maintain it as far as the page shows. | openHAB Nuki binding |
| Node-RED | Unconfirmed | No dedicated Nuki node was found, but the search was combined with other platforms and was not exhaustive. The local Bridge HTTP API and MQTT support could in principle be used from Node-RED, which we have not confirmed. | Searched, no source |
| Hubitat | Community | A beta Hubitat app by an individual developer was posted on Nuki's developer forum in June 2020 for the Nuki Bridge, Smart Lock 2.0 and Opener. It is not an official Nuki release, and we could not confirm that it is still maintained. | Hubitat app forum post Hubitat compatible devices |
| Domoticz | Unconfirmed | No Domoticz plugin found when we searched for Nuki with several platform names together, which was not an exhaustive check. | Searched, no source |
| Control4 | Community | A paid Control4 driver by Domaudeo, sold through DriverCentral, supports Smart Lock Go, Pro and Ultra with built-in Wi-Fi via Nuki's cloud API and polls the status. The page does not say that Nuki makes or endorses it. | Control4 driver (DriverCentral) |
| MQTT | Official | Nuki lists MQTT for Smart Lock 3.0 and higher, naming Homebridge and Home Assistant as examples of systems that can use it. | Nuki integrations help article |
| Nuki Web API | Official | A cloud API for locks with Remote Access, or locks reached through a Nuki Bridge. It uses a Nuki Web authentication key, offers webhooks and a Swagger interface at api.nuki.io, and does not cover local control or offline devices. | Nuki Web API |
| Nuki Bridge HTTP API | Official | A local API served by the Nuki Bridge. The Bridge is found through a discovery call to api.nuki.io, and an /auth call plus a button press on the Bridge enables the API and returns a token. Calls then go to the Bridge's local address without internet access, though the Bridge still reports lock status to Nuki's servers. | Bridge discovery and HTTP API activation |
