How in the H0LLY H3LL do I add Nuki SmartLock v4 to Smartthings w/Samsung S23!?!?

Devices & Integrations

So here is the hardware:

  • Nuki Smartlock v4 working fine with matter enabled
  • Smartthings Hub v3 “Connected” to the home network
  • Samsung S23 connected to the home network
  • Nuki App with the smartlock added and configured
  • Samsung S23 with the Smartthings app working and Hub working

HOW IN THE H0LLY H3LL DO I ADD THE LOCK TO SMARTTHINGS?

  • If I go to Nuki app - Lock - Settings - Setup - SmartHome - Matter - Add new system

and I choose smartthings

it does open smartthings awaiting me to scan a QR that DOES NOT EXIST but that I can type manually. ONCE I type it, it stays in a screen where it reads “Get your device ready”, no matter if I enable pairing mode in the Smartlock or not, I just can’t add it. It won’t go past that point!

If instead I go to

Google Home app
tap on the SmartLock (which works fine from there)
tap settings
tap Matter
tap Link app and services (0)
tap Smartthings

it goes straight to “Get your device ready” and the waiting starts again.

WTF?

What do you mean? Where does the code come from that you’re typing in manually?

The Nuki app puts the device into pairing mode and the QR code is the one on a card in the box. There’s also a tiny Matter QR code printed on the device itself.

Nuki Ultra, for example:

Just read your post again.

Google Home app
tap on the SmartLock (which works fine from there)

What do you mean? Is the lock already connected to a different Matter controller?

Yes, Google Home, but t thats not a limitation right? or is it?

I cant find the box, so my only reference is the smart lock. In the rear theres a tiny QR which is invalid when presented to the QR reader and a matter sticker with all the digits with manual input.

BEsides google home, which controls the whole house, i need to pair it with smartthings so I can use the new NFC pad with it, as the NFC only works with Smartthings hub, not with Google Home hub.

  • I’d strongly recommend to connect the Nuki lock directly to SmartThings and not via Matter Multi-admin - so delete it from GH and add it to ST.
  • Read this.
  • I’m not sure if Aliro/Digital Home Key works with the current versions of the SmartThings and Samsung Wallet apps.

Well, deleting it from GH and adding to ST later made the trick… geez.

Thanks!

You can safely add it back to Google, ST App, Lock, settings, share with other services, qr codes, copy code, open google home, +, device, scan qr code, setup with matter pairing code, enter matter pairing code, next, follow prompts.

Upon entering “Share with other services” I’m never presented with any QR code, just an invitation to open any other “matter” app… but anyhow,it worked too.
