Ultion Niuki G5 pro not connecting to the mqtt server

Nuki APIs MQTT
1

Hi,

Earlier, I emailed the support who directed me here. I bought this product as mentioned in the subject here is my issue (copy/pasted from the email):

‘1. Update Smart Lock Firmware’ - My smart lock firmware is 5.7.9 which I believe is the latest.

‘2. Connect Smart Lock to Network’ - Wifi is enabled in the lock and I can see that it is getting an IP address

‘3. Check Protocol Versions:’ - My MQTT server supports 3.1.1 and v5; I dont think protocol is an issue
'4. Verify Client Identifier:

  • Ensure that the client identifier is unique and clearly assigned to each connected client.
  • Contact the Support Team if the app indicates an incorrect identifier causing MQTT connection issues.

’ - Well the lock doesnt even reach this far. Here is what I did.

  1. I sat near the lock with a laptop and my phone with the Nuki app connected to the lock through bluetooth - all connected to the same wifi.

1a - Lock Wifi enabled and I see the IP address of the lock in the Nuki app

  1. Tailing the logs of the MQTT server from my laptop
  2. In the phone Nuki app, Opened Settings → Features & Configuration → Smart Home → (OTHER INTEGRATIONS) → MQTT and pressed Activate - It takes me to a screen where I provide the ‘Host name’, ‘Password’, ‘Auto discovery’, ‘Allow locking’. There is no save/Ok button but a ‘<-’ at the top to the left of the ‘MQTT’ text. Once providing the IP address and the credentials, I dont see that the lock hits the MQTT server - no connection attempt captured in the logs. And when I press the ‘<-’ all the information I provided are gone the button stays ‘Activate’.

3a. At the same time, I tried hitting the MQTT server from my laptop with the command ‘mosquitto_sub -h -t test -V mqttv311 -u -P ’ and I can see a hit in the MQRTT server log. So no MQTT server issue.

Looks like the lock is not even attempting to connect to the MQTT server.

I tried closing and opening the app, locking and unlocking (and again closing and opening the app) with no success.

Hope I have covered things in detail. Please let me know if you need more information I may have missed above.

Thanks
