Nuki APIs MQTT
1

Hello, after last Home Assistant updates Nuki integration don’t connect my lock trough Nuki Bridge. So I want to activate MQTT. I have mosquitto broker for MQTT and use it to connect zigbee devices with zigbee2mqtt.
When I open Nuki app and go to Settings>Smart Home> MQTT I want to click Activate button but nothing happen.

I have the same problem, I assume that you are not connected to the Thread network “correctly”. You need to enable NAT64, which is my case, is not possible with a Google Home Hub.

I don’t know I need thread network to use MQTT.

Now after Lock upgrade I can click Activate button but don’t know how to fill the fields.
I try:

  • mqtt://192.168.0.208:1883
  • 192.168.0.208
  • 192.168.0.208:1883
  • mqtt
  • mosquitto.
    Don’t have more ideas what I can use. I don’t have password for mosquitto. I use mqtt://192.168.0.208:1883 in zigbee2mqtt.
    Everytime I get 8E error.

Is there any guide?

I had some problems with connection too.
I just used my hosts broker ip (192.168.0.208, no mqtt:// or port)
And the username and password i set my broker with.

After 3 or 4 8E errors it finally connected.
The point is , your mqtt broker is probably not the issue.
I would check the logs in host to see if anything comes up (timeout of nuki or smth?)

Did you ever find a solution? I have the same setup and the same problem.

Just found the issue. My Nuki was connected to the guest Wifi which put it outside of the main network. Once changed, it connected fine.
